Absolutely useless, waste of money. Has 0 settings, inaccurate.
Absolutely mind blowing and accurate visualizations. Helps with so many things. Thank you!! The people who reviewed this less than 5 stars do not understand its value.
I’m surprised to see so little reviews on this. And the ones who did obviously do not appreciate what it is this app is. It would cost you a lot of money and resources and time to duplicate these results on sand with a chadali plate. To be able to see the exact frequency (I will test more)of real time sound is a HUGE SUCCESS and I appreciate your work. May I make a suggestion and I already know you know what I’m going to ask lol. Can you make the tuner more accessible if possible. At least the solfeggio frequencies perhaps 👀 I know that is a lot of work but it would absolutely make this app ELITE. I APPRECIATE YOUR HARD WORK even if others do not realize what it is you’ve achieved here. Congrats
i thought i was missing something, but the other reviewer said it just right so.. what in the world what a waste of money bummed
Charging 12 dollars to basically see a different picture linked to notes on the piano. Can’t believe I bought this.
