insTuner - Chromatic Tuner with Tone Generator

I constantly use this app when gigging or teaching. It’s on all my mobile devices, along with the metronome by the same developer.

I have used the paid version of this app for my voice, guitar my wife’s students. We both have helped sell many of these to our students. The strobe setting is the best for voice. Both of our apps quit doing the strobe but instead do the simple read m out on the free app the app quits when we got to settings. I went in and downloaded a second one for 3.99 but that doesn’t work either. I am using an iphone at 17.4.1. I’m sure I can fine something else but my students and i rely on this app. Can you help and maybe refund my 3.99 too. Thanks Peter Thomsen

Very good

I recently deleted an older InsTuner App and replaced with a new purchased version because the old version crashed as I selected the settings icon. The new version works to begin with , but eventually crashes much like the previous app.

Crashes constantly

So far it was free and helpful.

I purchased the pro version of this app several years ago and was initially very satisfied with it. However, the app no longer works and crashes every time I try to use it. I have attempted every possible solution and even reached out to Apple Support. They provided general advice, such as performing a hard reset of my phone and reinstalling the app. Ultimately, they informed me that they don't have control over developers and did not share any contact information for the developers. The developer's website is inactive, and I could not find any contact details. I recommend not wasting your money on this app.

Paid for the upgrade cause free quit opening. One day later, paid doesn’t open either.
