What happened? – GuitarToolkit - tuner, metronome, chords & scales Review

I bought this app years ago, for 9.99 and now all the features have disappeared including the custom tuning feature where you can select and save odd tunings. My tunings have disappeared in an update and now you want me to pay twice a premium price for being one of your early adopters. So let me get this straight, app gets less appealing; you wipe out my personal data and i have to pay double for that privilege? Lame
