Android App Testers Needed

I'm in need of individuals to test my Android fitness app.

Need to test all features and provide "detailed" feedback, including positive and negative points.
Also, tester will need to do various workouts/exercises as per app to test auto-tracking feature of the app.
Need to provide marketing / promotional feedback along with functional feedback, like how app can become appealing to more users and why users may not like to use the app.
