The app API scanner is good simple concept, I would suggest removing the other programming into separate apps. I would not launch into the the first thing. It would be better to have an explanation page as to what the app does. And how it can be used to diagnose issues.

What is this app supposed to do? It scans the apps on my phone and tells me what version of android is needed to run them. I could not successfully edit any icons or pics. Hide pics works not at all. Maybe its just me but it seems like it really does nothing useful. What does it actually do? Developers? Edit: I apologize for my harsh review. I changed my rating as well. The api does work great.

I'm sorry that Boundo failed your expectation. I'm committed to making Boundo better yet bugs keep coming out of nowhere. I have done all I could. I'm just a student majoring software engineering, don't expect Boundo to be as of high quality as other apps. App API is the primary function of Boundo. It does do something, something you find useless.

I wonder how rating apps pretending to be some clever wise guy feels. Silly to say an app should be free or not even attempted if it's not the best. Hey, clever guy, where's yours? I'm impressed when anyone steps up to create helpful apps and it's cool to watch them grow and learn as they go. Nice work Dev, keep climbing, reach higher. You're on a good path and I look forward to other helpful tools and apps.
