Other iOS devices which have microphones

Note: some users have reported that the microphone is not working in the latest release immediately after updating the app (especially users of iOS 9). If this is the case, reboot your phone (holding power & sleep button down for 20 or so seconds). The software should work as expected thereafter. If this does not resolve your problem, contact support (support@mauvilasoftware.com) with your OmniTuner version as well as the type of device and your iOS version.

My first & still my favorite.

When the App Store opened I downloaded this app. I like that it shows me a fret board for so many string instruments & shows me with simple lights & string colors that the string is flat or sharp. Other display choices, e.g., analog needle. I always restart it so it calibrates nicely. Started with iPhone Original all the way to iPhone 6 Plus, iOS 9.2


Ditto a watch app!!

I've been using this app for several years and it works perfectly for me. It would be wonderful to have it on my watch.
