Unusable app now? – RPM - Turntable Speed Accuracy Review

When I first downloaded this app location I was able to use it with voiceover but apparently some changes have made it completely unusable. There are settings that may fix that issue but they require payment, and I will not pay for an app until I can verify that it will work with voiceover. What needs to happen is extra features need to be in abled for a certain number of days or tests or something similar so everything can be evaluated for blind accessibility before I am asked to pay for an application that I may not even be able to use. Having these extra features require payment when they benefit the makers of the application more than a benefit the users of the application also seems suspect.
