Initially I was happy with the app and had rated it at 5. However, as I progressed I've noticed a lot of bugs that's really irritating. 1. The app at times doesn't take the count accurately. 2. It hung and didn't take count at all. 3. It doesn't take the 3rd string count while playing Em. 4. It jumps to the next chord even before I strum. I am looking for a good accurate app, if the trial version has so many faults with what confidence should I pay for a subscription. Disappointed to the core.
