There are two reasons this became the best guitar tabs app out there. #1 Everything about this app works amazingly. Flawless set up & maintained. So many good songs. Real time playback. #2 its afforsable price made is extremely accessable. Unfortunately, after this app atained fame, the price was raised to a subscription, which I find very sad. If this app was super affordable as it was in the begginning, 10/10. Since its much more pricey now, 8/10. Still the best app to learn guitar regardless of price though.
