Sorry, but if you expect people to pay for your app the second they install it and don’t even give them a 10-minute free trial, you’re going to lose a lot of potential customers.

Hi, thank you for your review. We have a free and a paid version of the App. Our Premium (paid) version opens up more opportunities. You can try it out during the free trial. You may also wish to choose the free version with fewer features available. But we are sure you will enjoy the Premium version, it is definitely worth the money!

Simple. Simple is good. Note that the app does not use the phone's accelerometer to measure angles - it's just a protractor.
