Made me purchase the full version and now doesn’t work

This app was working great this weekend but when I logged in today, it said it was only a trial and I needed to purchase the full version. I did and now the app doesn’t even work! I’m going to try to get a refund.

Update: I deleted the app and reinstalled and now it is working perfectly. Must have just been a glitch. I changed my rating to 5 stars.

Love this tuner and have tried many.

Bought a few others like Tonal Energy which is good but I wanted easy custom tunings where adjusted by semitones & this app comes with tons & so easy to enter your own QUICKLY. Big full screen tuner is easy to see from across the stage.

Best tuner

This is probably my first review I’ve ever done for app. This is easy and as complex as you chose. Seeing hz. And being able to change temperament is exactly what I was looking for. It’s apps like these that make your phone one of your most valuable tools.
