Even the free version brings quite a bit to the table. It could use some improvement with some of it's given features, like updated intents to specific setting locations instead of taking me to some easily openable place under my regular settings. More of a "hidden" settings kind of intent. Maybe also add launching in app activities that can't be launched normally.

I mainly bought this app as a Decompiling tool. The decompiler crashes the app on a pixel. Please look into this. The rest of the app seems solid so far. *Edit: this is just one of its many features. I still think this is a solid app. The work around to my issue is to keep the phone screen on with the 30 minute screen timeout setting turned on while decompiling.

Sorry, This is a known problem, we are still optimizing, but the problem is more complicated and it will take some time. We'd really appreciate if you could rate us more stars on Google Play for other features. Rating is very important to us in establishing trust with our user base. Thank you.

Life saver for an inexperienced phone fixer like myself. I don't know how many apps I've been through but this is perfect in my opinion it works for me couldn't be happier. I got hacked and it's been really bad the past few months. I'm content now.
