Reviews From google play store

UPDATE: I can't buy the key due to lucky patcher install, but I legitimately want to buy the pro key. I could just uninstall and reinstall it I guess. See what I don't get is I could just compile my own version through GitHub. Can you add a feature to search files for text? And a feature to ignore decompiled files that failed more than twice? because it just fails and doesnt show files that were already decompiled. Also i can't buy the pro key.

Great app. With the latest version however, you cannot see decompiled code as the viewer just continues too load.

A surprisingly useful decompiler - didn't think an app would be the right form factor but this one is great. selection of decompilers with a usable gui and zoomable code view. Wish that failed decompilations (which are naturally unavoidable in some circumstance) still provided an AndroidManifest, but as is this is an easy way to check what apps are up to on your device and debug simple problems. Thanks!

Bro you have done it nicely ,its very useful for me,but there is slit PROBLEM, now after a few updates, old decompilers are not available for me, I really need jadx decompiler but now i am only left with cfr. If you can give a option for choosing old version of jadx, it will be very useful for me (ANDROID 4.4.2, SDK - 19)

can't open, app force close. logcat say "Unable to open connection to debuggerd: Connection refused"

very nice decompiler




awesome app

great app.....👌👌

exactly what I was looking for in an app for just as X when my browser doesn't want to let me have Java for the things I needed for. this is nothing new that's going to try the app and see what happens to be helpful. So far so good. the ads are a little less interesting than usual but I'm sure that will change in the future. thank you

I saw some review bad that it can't copy but I still download it and I was able to copy. Best app I have even seen. Thanks Alot. Referred from a YouTube channel

The latest version is not able to decompile many applications. I am using Android P. Please fix issues and update the application

The new version is great, the last update introduce many improvements. I am very excited about what is to come for the future of this app

After decompilation an app, I am not able to share that decompiled file or neither can't copy them. So then why there's a share button created in the application? I want to transfer those files into my computer but unfortunately i can't. Annoying!

can't open any java app even an java book! but to dozens ad in this garbage!

App keep on crashing everytime.. app closes immediatly if i open. fix the issue. android P Nokia 6.1

now, new versions is bad, can't decompile with jadx. Im very sad. OMG!!!!!!!!

How do i extract files to my computer sharing feature is not working tell me i will give 5 stars then
