Could be way better +the only Lua interpreter for Android that really works —no Android API hooks —incomplete IO —horrible interface —a few bugs —after ~100 function calls the interpreter terribly slows down performing ~2 steps (function call, loop enter/exit etc.) per 1 second

Brilliant I use Lua for short programs so this is ideal. OK you don't get the interactive console but what you do get is a good editor, code snippets, android specific functions and decent error checking on running. I have run an android Lua console binary under a shell but this is far better to use.

Emmanuel Ramos

Epic When I'm bored, I use this app. This helps me practice solving out the problems I need, like arithmetic sequence, tables, and more! I mainly use ROBLOX to script Lua, it requires Lua 5.1, so it helps me understand more.

Leon Belmont

Great If this app bundles with some network(e.g. http support) libraries would be even better.

GL Zeng

Thanks That's what I'm looking for. Better than the sl4a'lua support.

Wade Rauschenbach

I've only messed around with it a little, but from what I've seen it is a great app for writing simple lua programs.

Darren Jones

Great app Works well, however coroutine.resume doesnt return correctly

Martin Judyski

Great Lua notepad, by far the best Android app of the sort. Snippets and samples are awesome for beginners as well as the overall layout. Well done!

david fli

Love it Works like a charm, if you could let us edit the layout or colors it would be 5 stars

A Google User

Very Recommended: I love it more than it was before. Keep up the great work.

Michael Morash

Nice and Simple Provides a simple way to program in Lua.


Awesome !!! another addition to my lovely arsenal

Billy Potatobag

I greet you good Sir! The best if not only (lua) coding app on the market. Plus no ad's or any payment whatsoever! This app was made too make people happy, and for that I'm greatful.

Hao Zhang

The one and only! Thank goodness a lot of thought was put into this beautiful app; usually when you're given only one choice it's absolutely appalling.

Dev Miner

Thank you! I'm very grateful that someone took an initiative to make development app for Lua only. Now I can code anywhere. Even when in the toilet! Thanks a lot developer!

Jakob Smith

Awesome! Works great on my tablet and phone and its great for passing the time,passing around or making little scripts! Its exactly what I'd been looking for! Thanks for a great app!

Pim Ouwehand

It works... Okay, it's a good app, but it has lagg, print doesn't work correctly with variable's , and local doesn't work. It sees clear() as sleep(), and you can't use But I can still use it for simple programs, except those longer than ±30 layers, or it will lagg, and sleep() (or clear()) will last 26 times the normal time.

Aleksa Haker

Great 10! No ads, no access to not needed things in phone good job i would like if you make for java or c#

sheldon cascarino

Pretty good I love LUA myself it's my favorite language :)

Arakatski Sudoiske

Time killer Really kills time when you have nothing to do

Alan Musselman

Good job Love the ease of use with Lua, simple and clean user interface.

Sinister MotE

Love it. It'd be nice if you could have the code auto run when you start up your device or sign into it.

JxMonster x

Love it! Enough said.

Gabriel Canto

Default APP Couldn't find a way to make it default app to open .lua files, 4/5 for that

Andre Arpin

Great app Works really well. The editor is good and the app is very stable. No adds.

István Donkó

Too awesome to be true!!!! Unbelievably perfect! Awesome interface. Syntax highlight, good file management. No separate output window to switch back and forth. Totally free.

Mitch Hudson

Cool I've always wanted an app to program with

Kade Farbo

GREAT I love this app. Helped me brush up on my lua. I use it more than sl4a lua because this is less buggy and all around better. I love the new syntax highlighting.. I'd love more samples though.. maybe one for calling functions from other files?

dakotakim z

Brilliant must for lua lovers Thus with their constant updates and new highlighting makes programming lua on your phne so much easier. This great app!!! Keep updating


Perfect They fixed the bug, so now it is an awesome app. I'd x definitely recommend this one

Manolis Vrondakis

Very good! I've always wanted to have a tool like this so I could muck around in public places. Lua is also a very easy language to grasp and is easy for beginners to learn so having it on your phone makes you compelled to learn and to show your friends cool stuff :P I'm satisfied. while ImSatisfied () print("I'm satisfied.") end I'm satisfied. I'm satisfied. I'm satisfied. I'm satisfied. I'm satisfied.

Kenji Kamio

Its good I also use this in my computercraft mod i just like programming im a cs student so it wasnt so hard :)

Benjamin Fischer

Almost perfect :) Everything about it works great. The only thing I ask for is an IDE. While unnecessary for some, it's vital for new to Droid users. Other than this the app is perfect!

A Google User

Uzwol bartaula Plz do also make a c-programing software it would be of great help 4 me thanku in advance

Gwillym Pitt

SD card It says it installs to the SD card. It doesn't. As small as it is it keeps telling me "insufficient storage space" after downloading and trying to install. So yeah. Don't like apps that say they install to SD memory and then they don't. Hope this gets fixed. Then I'll slap 5 stars on my review

Keith Banter

Horrible interface, incorrect programming The interface is horrid, and it gives me false errors apparently () is not real...

Scott Ivie

Very nice program. I'm a beginner so it would be great if there were more samples. But I can't complain too much.

A Google User

Nick This is a really good app, much better than any other I've seen for other labguages. Too bad it crashes on

Мартин Гончаров

Useless Output doesn't even work sometimes. Print lags, no wait()works

Alex Tuzov

Great Great thanks to developpers

Пользователь Google

print Printing tables and functions not working: print({ ["a"] = 123 }) Should print something like table: 0x000e6e80 Will be Debugger (Step-by-Step Execution, Watch Window) implemented?

Jeremy List

Very useful This app is very useful when I know an algorithm for something I need to calculate but I haven't carried my laptop. I would give it 5 stars if I could copy text from the output box.

Samuel Hunter

Great mobile ide, Can't use SD Card Barely any data used and the EULA is not invasive. The only thing I could say it needs is a more visible menu bar. Perhaps put it to the right of the quick options, instead of above it. *Edit:* Another thing to mention is don't bother trying to save to your sd card.

Peter Laloli

Really nice app for creating and testing Lua programs

Caleb Goldsby

Helps with my lua addiction Now I can code at anytime during the day to help with my lua addiction. However, I would like to see plugins for modified versions of lua. Specifically, I'd like to see a Garry's Mod lua plugin.

Philip Mowrey

Looks nice and as easy to use as could be expected. Iv been using it to test formulas for my game and it does a great job for the most part.

Oyon Ganee

Good app I use this app for teaching algoritm

Richard Barr

Somewhat useless Nice editor. There is no separate output page or access to the android api. You are limited to text output on the editor page. This is only a toy.

hasan baabad

nice liked it

TheBlue Diamond

Wow. Amazing. But can't to some commands. I tried wait() and don't work.
