Free tuner that maps chord charts to alternate tunings — looking for feedback

[ravivyatom]

Hi everyone,

I’m Raviv, and I built Stay Open Tuner as a free tool for musicians who like exploring alternate tunings.

The feature I’m most excited about is that the chord charts follow the selected tuning. Switch from Standard to DADGAD, Open D/G, Drop D, bouzouki or another supported setup (or enter a custom string map), and the tuner targets, chord charts, scales and riffs follow that map. I built it because working out familiar chord shapes again after retuning can take time, and I wanted an easier way to explore the sound.

The app is free, with no ads or account. It’s available on iPhone/iPad now. Android is in Google Play closed testing while I gather musician feedback. For Android, both steps are needed, using the same Google account: first join the tester group, then opt in on Google Play.

If you try it, I’d especially value feedback on whether the chord charts make sense after changing tuning, and anything confusing or inaccurate. This is my own app, so please let me know if this announcement isn’t appropriate for this section.
