The instant I paid for it I realized I shouldnt have. I didnt even try it first but really needed a drop c tuning real quick so went for the in app purchase. It wont even pick up the sound of my strings except maybe 1 out of 25 times. The only thing it picks up on every time is its own volume when it gives you the sound of what the string should sound like. Maybe for the standard tuning you can use it when youre in no hurry and can pick strings for 10 minutes, but other than that, go elsewhere. They would have an amazing app if they would fix this issue.
