I'm a pro user now  i recommend you do the same HOW TO USE THE PLAY STORE - 1. browse or search for an app you might - need  want or enjoy. 2. look at permissions & verify all an apps permissions are in check with the apps needs. 3. read reviews. 4. if everything is good so far  install the app. 5. if you use the app for 2 to 3 weeks and you plan on continuing to use it then PAY the developers for their work by upgrading to the pay version of their app. do this regardless of any extra functions. do this to promote further development.
