What's New in GTK

1.7.6

October 29, 2026

• Position Finder now follows your selected tuning — the mode and key lookup uses the lowest string of the current tuning instead of assuming standard E, and refreshes when you change tuning. • Position Finder fret picker now reaches fret 24 (previously it stopped at 12). • Position Finder shows the correct spelling for flat keys, e.g. {bold:Key of Eb} rather than D#. • Refreshed app icon (with dark and tinted variants) and splash screen, with a larger splash image on iPad.

Updated app

Problem with tuner fixed so app now works very well

Response from developer

Please try this again with version 1.7.5, which I updated yesterday based on previous feedback. Let me know if it's resolved your issue. I'd rather you had a 5 star experience.

Tuner isn’t even trying to work

I didn’t get to the rest of the app because I didn’t get my guitar my guitar tuned before I got really frustrated. This app is too expensive to be this problematic.

Response from developer

I'm really sorry to hear about your experience. The tuner is very accurate, and was tested against guitars and frequency generators. Based on your feedback, we isolated the problem to the UX, where tuning was being picked up correctly, but not shown stably. This has now been rectified. Please try again using the updated version 1.7.5.

Brilliant app

Worth every penny

Very useful app for beginners to music theory.

Would love to see harmonic and other keys added to the position finder.

Response from developer

Great idea. This has been added to version 1.4.1 (among other improvements)
