Crashes every time I try to access the microphone.
Update to above review.

The developer has contacted me and assured me he is working on a fix for the iOS 13.x.x issue with the microphone.

I can’t ask for more than that. As soon as it is fixed I’ll make it 5 stars!

Developer Response ,

my sincere apologies for the crash when tapping the microphone button.
It’s a known issue - since iOS 13, my legacy sound processing engines does no longer work, and the app crashes.
In the meantime, I’ve bee looking for a new framework in order to make my app work again. Fortunately, I did find one today!
Please be patient, it will take 1-2 weeks until I get published a new release of my app.
Sorry for the inconvenience!

Not sure why theres bad ratings, I love it

I’ve been using this app for as long as i remember. its a great app, esp if you’re starting out and dont know a lot. the tuner is very simple and i even invested in paying the small price for all the different tunings of ukulele. i forget how much it was but its not bad its truly an investment. i hope they keep this app on here forever its my go-to tuner app :)
