Great 'official' tabs on the subscription and worth the money but just not a very good app. Loading new songs so often just plays the last one you selected and Tonebridge (although amazing) is poorly integrated. Also fails to update to your current song and needs to be able to tell if you're playing a bass, lead or rhythm part on a given song. Also really wish it was easier to zoom in on tabs as I play on my TV and can't 'pinch' zoom. Frustrating as you can see how amazing this could be.
