Ratings and reviews

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!

I cNno praise this app enough. I spent months working on an app for my wife to surprise her with on our 5th anniversary. My pc crashed and I was forced to factory reset. I thought my files backed up but they didn't. Thankfully I had the most updated apk still and used this app to extract my code!!!! Love it!

This tool no longer works, I have tried it on 5 different apk files that I would like to know how they work and it fails to decompile any of them. Update 4/5/2021: still does not work anymore, it is like the developers just abandoned it, everytime you try to decompile an app it crashes or stops responding.
