Great app This app has saved me from getting into trouble more than once. Auto-correct is not your friend and so is sending a message to the wrong contact. This app gives you a do over. Download it now!

You Are Nosey

I love this app. Stops idiots from drunk texting and saves you from sending ugly texts. ☺

felisha crawford

It won't delete message I've looked at the instructed video and from what it says I just swipe right welp I've swiped rightand nothing is happening can you tell what I'm doing wrong.

Tony Antonides

Not receiving pics... Can't use it in landscape mode. Uninstalled. ?

Chris Burtt

Pretty good Does what it says. You can set how long the delay is. Works well for me. No customization settings, though, such as font size, bubble color, background. No app lock. But great idea, and a good start.

sevyhnn dsynthesizer

More yes than no but...... I love this APP (GO AUC!) But I have a few suggestions... If it was able to utilize more system functions (save numbers, ring tone assignment) and also another theme or 2 I'd give it 5 stars.... But i guess 4 out of 5 ain't bad. I just can't have this as my default messaging app without that control.

tanjela starr

Absolutely amazing one of the best apps ived downloaded a must have

Kennisha Frett

I love the app I love it but I some of my numbers have no name even though my contact info is saved and also updates

Jon Riley

A work in progress. Bad news: the app doesn't always accept group messages, so I can't use it as my default messaging app anymore. Neutral: the developers seem to only respond to feedback left in reviews. Good news: scrolling no longer lags, and it supports Google Keyboard emoji (by long pressing the teal-colored button in the bottom right corner). Decent effort.

Chad Billings

One suggestion to make this great If you could set different delays or curfews for individual contacts... I have an ex wife, and it would be great if it could say wait a few hours then double check that I still wanted to send those messages.... It would greatly improve my life and give me an even firmer upper hand and moral superiority, plus i would feel that i took the high road more often. Thanks for the app and hope to see these or similar features incorporated soon!

Dj Eslic

Won't auto rotate App is decent but it doesn't auto rotate when you turn your phone. Please fix. ...(Galaxy Note 4)

amina wintersom

Love it but... Love it but I miss my emoji power.. .

Jade Sisson

Pretty great I really enjoy the options of bringing the messages back to fix typos, just wish the notifications would be precise in pulling up the specific messages, and not keep other message threads pulled up instead

T.D. Walker

Very good app Would like it better if notifications were more customizable. I hate when my phone vibrates. Also, being able to lock specific texts so they don't get erased would be nice


Pretty good I like it a lot but like the last reviewer said the notifications. I can be texting and get another text in and pull down bar to try an go to next message that just came in and it stays on page and I'm like uhhhhh sooo am I texting next person or nah lol. But it's cool tho. Def my default messaging app. Also can you Save Drafts? That'll be great

Sam Kilgus

Good app, great idea, amazing potential. I really like the idea behind this app. A few things I'd suggest/things I don't like: The keyboard disappears after sending a message (don't like that), color change when a message is sending (don't like that), scrolling is really buggy/sometimes doesn't work (don't like that), come up with a cleaner animation for the sending delay (the current one is good, but I feel it could be improved), make the customizable color scheme for the whole app. Good job guys, can't wait for more updates!

Concetta Plovanich

NO GROUPS You can't use your preset groups with this app. This would be a great addition. I was looking forward to using it but not without groups

Veronica Green

Love app but how do u clear message history can't figure it out

S McKenzie

So good!!!! This app will save you from auto-"correct" demons and accidentally sending to the wrong person. It works perfectly. I like the curfew for those low-inhibition nights too. I would like to see a couple features, such as voice messages (like on WhatsApp) and smiley faces, but that would just be a bonus. Like I said, the app works perfectly.

David Acosta

Android wear Doesn't work with my LG G Watch R

Brandon Gilliam

Great app! The app is a life saver... Or at least it could be if you're texting multiple people! Still missing a few key features to give it a 5 star, but I'm sure they're coming. 2 things to fix is making the photo saving a 1 click action and save to a messaging folder And when you press the back button, it takes me to previous text messages, even if I've deleted them; it's enough time to take a screen shot. Back button perhaps should take you to the main screen look forward to the updates!

Andrel Thomas

Saving MMS Would get 5 stars if I could save pics and videos to the phone.

Ian Hayward

Mr RONALD KRAY DID GO IN BLIND BEGGERS PUB NOT FOR A DRINK !! Do you now how expencive sms messages are xxx

Shakim Allah

LOVE YOU SIS FOR THIS APP Created by a Black Woman

ramon henderson

Holliwood Great ap why didn't I think of that way to sisters

Scott L. Steward

Awesome I think this app is awesome. It solves a real problem for me.

Mary Jo Allen

Almost perfect. Would be perfect if we could save pics. My kids are in other states and I save all the pics they send. I did recommend it to all my kids.

Star Fisk

Just finding out about this app. And its a life saver!!!


Good concept I like the concept of the app and that you can change the amount of time you have to delete the message. BIG issue for me is that I get no notifications when I get text now.

George Kammerer

The idea is great but the app lacks many features that I use constantly (samsung messaging). I'd like notifications, abbreviated message along top of screen when it comes in, ability to add contacts, copy text message, & more. If the app updates with those I will reinstall.

Robert Bonner

On 2nd Thought No more mistake text messages

Tifany Harrell

Great App I really like this app. Great job. Just one question. Can or when will you be able to use emotions or pics within a text?

Ariyana Shines

Saw Saw it on wgn,installed,it's cool!

Eric Werner

Can't save photos to your Gallery Can't save photos to your Gallery from an SMS message... That sucks!!! Following up... The App doesn't save to my gallery there's not even an option for gallery.

Lorraine Diamond

Saved from the Oops.

Victoria Crawford

Great This app helps so much with typos and sending things to wrong ppl or even sending something you will regret... ❤

Evelyn Reed

Needs more features I would like to see number/text blocking. There is no option for that. And scrolling thru previous texts is really slow and delayed. And maybe more color schemes beside orange/gray. But my #1 would be a text block option

Carla Adagun

Loved it until it stopped working for me The features are a bit sparse but I still liked using the app. One day, it sent a message without the take away option. Then it would idle on send forever without sending. Had to switch back to what I was using. Also, please make the font more bold and user friendly to the eyes. Keep up the good work!

Gwen Benton

Cannot delete old messages I just installed the app. So far it is working well. I can attach pics. Only problem is i can't delete old messages. Also be aware this has to be the default messenger, but all your messages move to the app and your can always switch back without losing messages. Correct the delete issue and i would give it a 4

Cliff Hess

Great App. Exactly what I need, BUT it locks up/freezes constantly. In fact, sometimes it locks up my entire phone! I cannot use it. I have a new Droid Turbo with no other issues...

Tiffany Trammell

Need some bugs fixed I noticed that if I send a text with an attachment that the recipient may or may not receive it. When someone is sending me a text with an attachment, it can taken up to 12 hrs for it to deliver. I love the concept of this app, just need it to work right. I have a Droid phone, please address.

Patrick McGee

Group messages Group messages received only gives initial of first name of sender. When more than 1 person has same first initial in first name, can't decipher who's sending text in group message. Please add ability to look at details of text message to see actual name of sender. Other than that, great app.

A Google User

Not receiving pics... Can't use it in landscape mode. Uninstalled. ?

Mz Lady

Delete/swipe inoperable No authority to delete though swiping right. It only covers text sent on the apps existence. It can clear previous apps

Isis Simmons

Delayed messages The messages I send and receive sometimes take as much as a whole day to go through.

Danielle C. Jackson

? I love this app so much!!!

Clover Eckert

I love this app, except for the fact that my pictures never send. Is this a bug that can be fixed?

Nancy Valdez Chun

Can u add a function to change font size and colors? Love this app. Thank you and Aloha

Jacob Adams

Floating Chat I love this app, but the floating chat is really laggy (i do know its beta and things happen, but just sayin). I would give 5 stars, but letters keep getting cut off on the edges of a message

Gio Camacho

Its good but When my message is sent it sends it multiple times, well it shows it does but theyre only recieveing it once. I just dont like that it shows that

alma banks

I love this app I have told all my friends and relatives!!!

Lynnisa Ballard

MRS message I would give it more stars..but have updated app and still unable to get mms messages.....

Ayanna Tesfaye

APN My phone doesn't have an APN and OST will not leave me alone about it. A bubble appears that says 'No APN specified for this device. Fix this in On Second Thought settings.' It takes up the bottom of my screen and it's not see through. Would not recommend

Melissa Reyes

No mms I was going to rate a 5 but all of a sudden my picture texts l isn't downloading. I have to go to factory installed messaging and then go back to ost to be able to see my picture texts.


Lacking a few key improvements This app is really nice and useful. Its easy to use and customizability of choosing delay in sending text is convenient. However a few cons are that when the app is opened it takes a considerable amount of time for the conversations to be displayed. And than sometimes clicking a conversation doesnt open it which means waiting to see if it opens. Than when it doesnt, one has to click again for it to open. The other issue is I can't delete multiple conversations at once. Overall a good app but needs improving

Jon Foxe

Stupid app It's slow and the grace period is only a minute. What a waste of potential

john leslie

#Niceeeee app but need more options as far as SMS skins or adding a background to display it'll be 5 stars when that happens but definitely worth the download

Jynese Bostick

Need help Just got the app but my problem is that I already have a text that I'm wanting to delete before I downloaded this app, is it possible.

Barb D

Just downloaded your app. If all goes well, I will give a 5 star!. One thing I don't see is how to, if you can, *delete all messages at once? Instead of one by one. *Also, I miss not having Favorites for people. Maybe your "frequent contact' will have them. Cuz I hate scrolling all through my contact list. Time will tell :-)

Eric Sibcy

Good app! Great for those texts you accidentally sent to the wrong person!

Techna Elizabeth

Had to Delete Wasnt getting my multimedia messages till later and mutlimedia being sent wasnt going thru properly

Easter Crawford

Good app that has some kinks It's saved me from more than one faux pas. But I've been having some issues getting MMS pictures and occasionally group texts are delayed without letting me know. It'd be great if I could also schedule texts to be sent later.

Shay Anderson

Pic problem It take days for me she send pictures and receive them

Renee Mitchell

Love this app! Is there a block feature to the blacklist unwanted text messages?

Tisha Holmes

Excellent Created by a genius. Loving it....

Sarah Johnstone

It's excellent But would be nice to have diff colour/s to choose from apart from that have had it a couple of months and no complaints... ?

B schmitt

I really like this App. I gave it four stars because there's two things it doesn't do that I wish it did. Landscape mode and Text to Talk (it doesn't work with my Droid Turbo) Other than that I really love the fact there's a delay, which gives me plenty of time to retract if I need to.... I have problems hitting the send key by accident, so this helps ALOT!

Ammi White

Good Idea, Waiting for Great I love the idea of recalling a text BUT this app is infinitely slow to load, open, register that a message was sent or received. I've even not received a message at all in some cases. Looking forward to the upgrades and changes. Great concept though.

Symone Walker

Really liking the recall/edit feature. Wish this feature extended beyond 1 minute but 1 minute is way better than not having the option at all. Could use some more bells & whistles such as notification sounds or more obvious notification of messages, such as displaying # of new messages waiting. Also I can't figure out how to build in a signature for each message. Only gave it 4 stars because the app is new to me and I'm not quite used to it yet.

Dominique Dixon

Love it I seen the app designer on The Real and I thought it was a amazing idea. I mean who haven't worried about what the receiver thought when they received a crazy text. It works perfectly.

Danielle Lee

I like it but... Although there is a notification icon in the status bar there isn't an option for the message to pop up on my screen and/or a text own notification sound. My previous text message app would list on my screen "new text message" and show who its from. The other issue is I can't share external photos from Facebook and other platforms. When you select on second thought to share the photo it does not populate. Also, is there a way to delete multipe threads and multiple texts without deleting the whole thread?

Lauren Wint

It's great to have the chance to unsend a text within a time window, and the curfew option is very helpful.

Jaraina Moore

Awesome I love this app considering I'm known for fast texting with the most mistakes

Da'Shawn Verrett

Love the app. I saw the inventor on The Real and downloaded the app. So far so good!

Kristen Ferguson

Love this app and the idea. Saw this app on The Real and downloaded it immediately. The only thing about this app is that my ringtones don't work and neither does my flash when I get messages. Other than that it's perfect

Markia Felder

I really like this app. I saw you on the Real and I was bought before you finished talking about the app. I love the delay of the message. I have two phones so I had to test run a couple of times just to make sure. And it works

steven gil

More then great! Had a similar idea about an app like this and now don't even want to proceed with it since I ran into this app. Great app invention guys!

Shea Stylez

I just wish it allowed you to customize your tones and colors and stuff that make android as cool as it is.

Angela Villafranco

Will see how it worsk Saw in the Show The Real andinstall automatically. I tried it and liking so far, like the process of deleting if change mind. Will share

Pearl Torres

Pboop I saw this young lady on the Real who invent this app. I just wish that in the up coming updates you could add on some more things like charging fonts,colors, spelling checker, and so on. Thanks I love it..

Shelia Lanier

Great & Innovative Seen it on The Real also & downloaded..Great idea & good luck..Great application so far, hence the Rating...:)

Tara Young

Great App is great! However it doesn't default to my photo gallery when trying to attach a photo. ..Please fix

Michael Campbell

Love the app Love the app! Simple and not complicated but I cannot create a text and send it to anybody. I have to go to my phone SMS to send to another number besides selecting a contact that is already in my phone. I have HTC M8, been like this since launch. Please add this feature. Other than that, this app is perfect. Keep up the good work!

Tanya Lots

Need sound That's the only thing I don't like; it doesn't alert me when I receive a text. I need the alert sound. Other than that it's a great App.

max james

So so No delivery notification and will not allow me to dial contacts direct from app..keeps coming up with "invalid phone number". Duh, it's not cos I ring it all the time! Fix these and achieve higher rating.

Brandon Patterson

This app is great with the potential to be one of the best, but has some issues. The biggest issue I'm having is that when I send an image or an attachment to someone it disconnects my Wi-Fi. This uses my carrier data plan and isn't cool. Also, you have to enter in a recipient BEFORE you compose your message. The app should allow you to compose the message before choosing who it will go to. That in itself is another safeguard to not sending a message to someone it's not suppose to go to. The app also needs a "slide" feature that allows you to slide on a message that is in your message list, and have it either call or create a reply message back to that contact, depending on if you slide left or right. This is a very basic feature that is on almost all SMS apps today. Would also love to see some options to customize the look of the app (themes, etc...). Again, the biggest issue is the Wi-Fi disconnect issue. If that doesn't get fixed soon, then I'm going to have to look for a different app. Only 3 Stars for now...

Rachel McDuffie

I'm so happy I found this app!! My phones messaging system was starting to malfunction and this saved my life. Love it so much! When I get my new phone will definitely be downloading again! ?

ron Davis

Great app The best thing since kool aide

john brady

I have the solution to your MMS problems It's that simple, I own the engine.. I emailed this to the address below.

james hillyard

Great app but I have a problem. When I try text a contact from my contact list it won't load. It works fine if I am replying to a sent text.

Dmitry Aistoff

settings, design There is no settings and poor design. Good enough for alcoholics :)

Jason Dean

Very Impressed I don't really rate or promote apps I download, but I feel this one deserves it. Been looking for a simple SMS based app to replace the stock app, and even one better than the popular texting apps in the play store. This one takes the cake for me. The only thing I'm hoping to improve is better carrier ID for MMS service. But that's not going to stop me from rating 5 stars.

Multi Thinker

Finally This app can play hide and seek by simply keeps crashing YAY!

Laura Palmer

Liar It just delays the sending of the text. False advertisement.

Scott Sears

Galaxy S6 users! Please! Read this! So, i downloaded this app, because i had just before sent a message that i didnt want to send, and i really liked it! It was easy to use and very nice, but i have to uninstall. that evening, i went to work, i wasnt there for, and i see that my phone wont turn on. It turned out that my battery went from 74%, to 0% in less than 4 hours. I got home and charged it, and it worked. Dont get me wrong, this is a great app.

Christopher Brunner

So Much Potential Great concept. Having a grace period to review a sent message is awesome. WiFi is temporarily turned off when you send attachments, which is a BIG problem for me. Also, many attachments just fail to send at all. This would be a t Star app if these problems were addressed.


Cool but slow Good app idea but very slow in loading when I open a group text. There is a delay when the message is sent out when you decide not to recall or undo.

Sean Sweeney

I've been using this app on my S5 for at least a year and LOVED it!! But I just recently got an S7 Edge, and now it loads conversations SO slow that I've been forced to switch to a different app. I tried clearing the apps cache, and that made it load much faster, but after a few more texts sent back and forth it goes back to loading very slow. Also, I think most of us would really like to see some theme/look customization options, as we're not all fans of Orange :). Overall, great concept for an SMS app, but with these new devices there needs to be an update that fixes the long loading of each conversation thread.

Robert Terry

Its Works and it works perfectly! After trying many hopeless apps that either do not activate or do not do what they say they do this app does absolutely everything perfectly. Would happily pay for this.


Needs FIX It fails to send a photo every time. That makes this app too much of a hassle.

Dalin Luster

Love this App mann!!! Much needed. Bravo. How about coming up with a way that messages can expire on the recieving end

sequan lloyd

Nice Good but I have to switch apps when receiving/sending mms

Gregory Lueders

Works perfect ?. The creater of this app is brilliant. I changed my msg app to this 1 as my default app. I recommend this to everyone. I msged my friends to change their MSG app to this 1. To the company that created this app, I thank you. Sincerely- Greg.

Ram Manohar Oruganti

Started out well but messages fail to deliver and I need to resend many times

Christopher Brunner

So Much Potential Great concept. Having a grace period to review a sent message is awesome. WiFi is temporarily turned off when you send attachments, which is a BIG problem for me. Also, many attachments just fail to send at all. This would be a 5 star app if these problems were addressed.

Juanita Vance

Great app from the examples they gave me after downloading. Only problem was after selecting for mms or sms not sure my data went off had no internet service. That's no good had to remove app.


Having some troubles Love the concept of the app and totally works for me. Only trouble im having is that when i try to send photos everyone is telling me they are not receiving them so im unsure of how this can be fixed. Other wise i would have given a 5 star

Gregory Rich

Takes forever to load Great concept but it takes 7 seconds to load. It might sound like that's no big deal but when you're talking about "instant messaging" I guarantee that will be more than enough to persuade you to abandon the app. The suspicious part of me also wonders what info the app gathers in that span of time.

You Are Nosey

I love this app but... For a few weeks now I've noticed that when I send a photo the app sends it sideways whilst other apps send it just the way I have it saved on my phone. On second thought version Android version 6.0.1 Phone model SM-G930T on T-Mobile

Stan The Man

Best messaging app Easy to use, and helps keep you from looking dumb, by enabling the user to correct a mistake before sending

Anon Ymos

Crashes Crashes on my one+ phone, or loads slow. So sad. Pls fix.


Great messaging app but.. I really want to see my smses delivered. Add that feature(notification) but other than that, I love the app.?


What an app! This app is a game changer. Will never go back to the way I use to send text. AWE+SOME!

em ily gsell

Help!! How do I recall an already sent SMS?!?!?!
