Great tuner app

Please keep updating this and adding new features. If I see you are still making this wonderful app I'd love to buy the full version. The oscillator is a nice feature for learning how the tuning sounds. Please keep working what you have done so far is great. I'd suggest an option to have the oscillator automatically turn off and a button to reset the graphs that isn't in settings. Thank you so much :)

Developer Response ,

Thank you so much. Great ideas!
I Will make some easy accessible buttons,
-to clear the graph,
-Set the sounding interval of the oscillator
-Turn Sound on/ OFF
-set transposition,
-set A=436 -450 hz
-Set accepted detuning in cent

I am currently testing.

Then I’ll be working on the oscillator, My idea is to have the tone fade in When there is input and fade out When there is no input.
After that I’d Love to have other sounds .
