Great (except for constant freeze?) – TonalEnergy Tuner & Metronome Review

I use this app every single day for practicing, teaching, etc. I love it! But recently after updating to iOS 13 maybe a month or so ago, the app seems to basically freeze, causing me to have to constantly restart it, multiple times a day. Anyway this could be fixed? Otherwise I would rate it five stars.
