Great app Tried it for a few days to make sure it did what I needed, then bought the full version.

march anjilo taguinod

Bunch of thanks! Really saved my day since it helped me a lot in resizing my font though my phone's not rooted. Thanks again!

Jennifer Clare Gill

Excellant... I am visually impaired this helps a lot!

Helen Todd

Big Font It was perfect untill you updated 2 or 3 times today, & now I cannot get it to work on facebook, and cannot select the inbetween buy the pro app. Deleting app!!

Christina McCrone

Awesome! Love this app to see better on my phone!

Jonathan Tyndall

Recommend to all android TV dongle users and older people with eye problems especially!!!

Brenda Bonfoey

I an legally blind. Thank you!!!!!!!

Druidess Midian

Great for shrinking font, but..... I'm long sighted, so need tiny fonts, which this app provides well - however, it causes system issues when trying to change the wall paper, especially if I try to change for one of my own pics, it causes the screen and pop up boxes to flash rapidly, forcing me to cancel back to menu. This needs fixing before I give full star rating. *EDIT* Thanks Sam, unfortunately I'm having to use an old "back up" phone while mine is repaired. The flashing issue has spread to other areas of this phone, so had to uninstal

G Hill

Nice! Still needs work though. . Dialogue boxes still 'squash' yes/no/accept buttons. . Still, this should be a stock item built right into the browser. Really helps those who are vision impaired - thanks.

Rolando Estrella

BigFont Nice font it can help my husband atleast now he can use his android phone now

Daniel Sreebny

Valuable app I've used Big Font for several months on my tablet, and it has been an excellent way to increase the size of fonts I on a variety of Web sites. Easy to use and very effective.

angelo lewis

Works like a charm All I can say it works great I had so many phone and As am getting up there in age my eyes don't work as good. most of the large fronts on phones is not that large....but this sets it to what ever size you it love it also works on my watch phone Es309...

Dale Hahn

Use it often Get a bit cross whne the font size changes by it itself and you have to keep altering it back

Cadie Pocket

It really works! But I got this major problem about flashing thingy whenever I change my wallpaper and everytime I open my bookmarks in the internet. Please help fix this problem. This app really helpful to me and what I've been looking for intead of downloading many fonts. Thanks!


Thanks to this app. Very useful when i forgot to carry spectacle

Ken Hiew

Does exactly what it should do... Would be a 5-Stars if font face changing is added in the apps.

Kerry Newnham

Good but Makes the nexus 7 font readable but unfortunately also stops ITV player from working. As you have to reboot to change font it's not necessarily a solution for newer android devices unfortunately

A Google User

Great app I am legally blind and by far this is the best app I have purchased. This app should be built into the system samsung galaxy s4

Prashanth Kashyap

Doesn't change font size throughout the system Please try to fix this

nicole fleenor

Loving it! I don't why the galaxy s2 doesn't have this feature built in but i love this app. Simply amazing.

Kosanta Lacoste

??cool This app is so awesome. ??i just ❤ it

Chris Kane

Does what I wanted. Sms larger. Thanks

wazed asif

good make it full free

JJBRules !

Good Helped with Stufg

Amalia Febeka

Didn't change I can't change my font size even though I deleted and only normal. I want to change to 45% but why it can't??? All they say to buy a pro.

Shahidur Rahman

Works well

Brook Risner

It sucks

Donald Rowley

New version I love this app. I use a Galaxy Mega because of near vision issues. The new color palette is better but I woild request that you use a black font instead of gray as it wotks for everyone including those of us with low vision issues. The other idea would be to give us a choice which Im sure would be more difficult and take up more memory. So please keep the people who use your app most in mind as you upgrade the platform. Thanks

Sharon Bell

Brilliant app;) I have bad eyesight and this app has changed the size of the text in messages, email, Facebook and loads more. So pleased I downloaded it. I couldn't recommend it enough especially if you struggle with small print like me.

Donald Rowley

New version Sam. Thank you! With my last review I gave you 4 stars and requested that you used higher contrast fonts in your set up routines. To my surprise you actually heard me. I can't tell you how much I appreciate it. for some of us with low vision Grey's are really hard to see even on a white background. Well you did it you made it right thanks for caring. 5 stars now. Awesome job!

Agnes Ong

I sucessfully installed bigger font to 250% for my mi 4i, now my contact list, message,whatsapp all big wording, I LOVED IT

Dawn Murtagh

Help Can't live without this app. But it won't work on Facebook and when I increase the font size I can't see the full words on my devise menu

Princess Prettie

And you know it Can't change the different font size for other apps that involve typing just the one.

David Kinlay

Another useful application... A necessary one that should be standard built in

Jen K

??Great~? First thought it was just gonna be okay. But its great~Suits me very well

A Google User

Amazing Absolutely a fantastic app, thanks with all my heart to the developer

Dianna K. Green

Love it! Love AND need it. Not needing to root my phone makes this my favorite screen enlargement app. Thanks so much to the Developer(s)!

Cade Esterhuizen

Wow Wow I finaoly foun what im looking a 5 star font app, im trully impressed with the developers achievement

A Google User

Great app I am legally blind and by far this is the best app I have purchased. This app should be built into the system. samsung galaxy s4 and galaxy s6.

Sly Ostinato

Clipped off words Whats the use of being able to increase text to 300% if the titles of apps are clipped off in the apps menu and you cant see them?

PS4 House VNP

BEWARE! The latest update has broken my tablet. It freezes right after the desktop is shown. Nothing to do except hardware reset.

Oleg GG

Doesn't override system setup. Doesn't work for xiaomi

Briant G

It's good in general. BUT many things are cut and not proportionately displayed. Could you advise me how to fix this? I am partially sighted but I want it to proportional thanks

Lynne Stewart

I rely on this app since I have visual issues that require a pretty large font. It seems to handle most apps quite well but (as an example) can't handle the Amazon Alexa app at all. I'd love an option to say don't include Alexa when changing fonts.

Andrew T

Don't change font size for specific apps? Please add this!

Melinda Rice

Nothing New they always want to charge you for other font sizes...uninstalling and going with another app


Great work. Awesome. Keep it up.

A Google User

Excellent Very useful for someone with bad eyes like me

hussam nooh

Seriously the best one ever. Thanks for the greatest team who make this app. Regards

خيرالاكمل ب. ازاني

Superb..thanks alottttttt

Dagoberto Ruiz

Works... ... But it seems to use a lot of memory, don't know why. And it gets my device hot. Uninstalled. Don't trust it.

LT Hong

Good app for varying font size, however it doesn't work on the Asus phonepad & Xiaomi phone. I have to uninstall it ???

Wida Mozart

Great but I need font weight changer feature, so i can have bolder fonts on my phone please i will then get you 5 stars

Sahir Siddiqui

Doesn't help me. Unfortunately, this app doesn't help me. Apps such as Feedly aren't affected. Other apps are blown out of proportion - system menus etc take half the screen, but the contents remain exactly the same microscopic size.

Nivi Morales

Good app for visually impaired Installed this app to make the font larger on my Sony Xperia compact Z3 and I found it to be very helpful. It allows enlarging system and apps font which made using my phone a lot easier. It needs restarting after setting up the new font size but so do most of these apps. I have updated to the full version. Really recommend it.

Nacole Galloway

Big Font It's a cool app needs more options to change size and maybe style n color. Also a possible widget to change other things like Facebook chat size or web pages bigger or smaller....

Mm De Borja

??? Does not work on messages.. That's the only app i want it to work..

Komal Khatri

UNINSTALLED it only changed my font in some applications and not at all on the basic applications

C. Ivan Mothershead, III

Do NOT USE Totally crashed my Sony z2 tablet. Had to do factory reset. CRAP

sunil shah

No support for pro version buyers The font size is stuck 140% and wouldn't change. Even after paying for the pro version the app is stuck. Using on redmi note 4g. Very disappointed


How can I make it work ! ? I can't find out how ! Help ?

Patti Casterline

Makes using my HTC so much easier. I have had this app installed for a very long time. So happy that I found it. No problems ever. Works like a charm. Thanks.

Mustafa Sarikaya

Finally found an app for this I'm so happy I found this app because I really got annoyed by how big the smallest system font was. Thank you guys!

Maly Nut

wtf it is not support my facebook.

Dirkie Hamelink

Great It works like a dream thanks

SuperStrawberry STARBUCKS

Not very stable app this ... My edge 6+has no problem with it, but my S2 will always revert to mini small fonts each time i turn phone back on after i shut phone off at night. I WILL RECOMMEND IFONT, CHOOSE HUGE SETTING, IT WILL STAy HUGE 4-EVER EVEN FOR S2. Trust me.

Piyush Maurya

Its working Wow m amazed

Dave Patterson

I'm serverly visually impaired and this app helps alot

Prakash Jain

Working a bit Good one

Dare J. Onadele

Magnified Fonts I was sick of my phablet having small fonts despite setting my default font at extra large. But upon downloading this app, the phablet now displays fonts to my satisfaction. The only challenge is that few other app fonts still don't get enlarged. Believe me, it worked for majority of the apps.

chandrakant joshi

Jakash Good for chasmish

Dianne hodel

HOW THE HELL ??DOSE IT WORK I was reading books? þut the font size of it went small?dont work either.? no why so thought I'd download this but make a difference ????

Loo Yake Kee

Suggestion If possible hope to have 220 percent enlargemen for small phone THANK YOU

Reeva Webb

First install on any android device i get. This app is one of the first apps i immediately install and setup on any android device i get. I'm a legally blind android user and this app is great if you need ginormous font on your device. Buy the pro license. Totally worth it.

Kehlee James

It works!! Wish I could get pass 50% for free tho ?


I love It!!! It's The Best... Because It Makes It Better; For Me, To See Everything On My Phone...

Satish kumar Vasamsetti

Lack of functionality All it does just increase or decrease the font size. Please bring the update to change the font style.

Nick Kalu

Easy to use Very simple and does what you want it to do. LG G4

Nilanko Halder

It works and just does its job well.

A Google User

LG Mach, ICS 4.0.4. Works as promised... Default font was too big. Could not read whole paragraphs without scrolling or losing content to the screen. Downsizing to fit solved the problem. Works better with new handset. ICS vs GB? Better hardware? Who knows??? Would be nice to have a separate settings for homescreen, lockscreen and menus, similar to my old desktop PC.

Olivier Laviolette

As another user said : Too bad it doesn't work for the ''main pages'', also if I change the font size in the cell settings, I have to restart my cell each time to enlarge the font back the way it was (with Big Font)

Gud job I like this apps coz u can use slider to adjust your fonts.

Dave Brown

Very good but I wish it would work on menus.

Bismarck Hesse

Good but can we have the option to change the actual font as well, as supposed to just the size ?

Brando Maria Rizzo

It does its job, 5 stars for you

But you want permission to take pics & video?

All of sudden,I have come across this app.Now I feel,i am fully satisfied......At last,I must congratulate developer who has invented such a beautiful app....???

Estelle Weiner

not quite what I had hoped for it's ok, but didn't work on a survey which was the reason I'd installed it. Some of the survey was ok, but most was not. I also would like to set a custom size font but can't seem to do this. Perhaps I'm not techie enough. Was hoping to install it on my husband's mobile but think it may confuse him.

Lisette Rivera

LR Love this app. Just one thing why I can't I use the font size 118. It goes from 117 to 119 always no matter how I try to input it
