Only worked once
I downloaded the free version and was impressed so I purchased the full version. The free version only worked once and the full version never worked at all. There was no sound. Deleting and re-downloading didn’t help. Great concept, poor result.
Response from developer
Tone playback requires the "silent" switch to be "off". Sorry to hear you are having trouble with getting sound from the app. Please let us know if you still cannot hear sounds after turning the "silent" switch to "off"
