Disappointed
Bought the full version and its a 50/50 chance the video will actually turn out. App crashes when the video renders. Compression greatly decreases the quality to the point of pixelation. When a video actually renders the audio just doesnt work. Running newest iOS on iPhone 6S+ should not be an issue.
