The worst tuning app I’ve ever had the displeasure of downloading
You can’t even open the app without being faced with an ad that takes up half the screen. You can’t play any tones without paying $2.99. You can’t customize your settings without paying an additional $2.99. You can’t tune your instrument to pitched other than standard concert and baroque without paying yet another $2.99. Why make an app be “free” if it’s inaccessible without having to pay almost $10 just to use it?
