The only time I buy anything on my android phone is after I've downloaded the free version first, found it was actually useful, and then upgrade and get the pro features. Apps are so cheap I have no problem spending the money, but testing the app out first is crucial because there is so much crapware on the app store! I literally do not trust buy-only apps anymore because of it. For example I wanted to log my gym progress in an app, and I had to go through at least 10 different apps before I finally found one that had the functionality I wanted (fitframe devs thank you!).
