It seems like the only two options to get tabs nowadays are gtabs and songsterr. I prefer songsterr out of the two, but constantly get harassed to buy the premium version and certain important features are paywalled.
Basically my question is is there a way to bypass the premium subscription to get all the full features or a better alternative out there with a database of tabs as large as the two have. I want to be able to hear the playback of the tab and control the speed at which it goes.
An app called Lamucal can make them for you, lyrics and all.
An older app (now defunct), can be found on archive.org, called Riffstation, can do the chords.
Once you have a version of your song you can put it in an app called JustChords. This app will store, display, and transpose your songs. It also has a search feature to pull tabs from other sources.
