Baffling to use
Ridiculously overpriced
Response from developer
There are many apps that can detect pitch or tune. But most apps don't declare their detection accuracy. In fact, their accuracies are all above several cents. Instrument performers can recognize the pitch deviation of 3 cents. Our app's Normal Accuracy is 0.36 cents, and it is 49$. The High Accuracy Function is 399$, which is for professional researchers.
Horrible
Response from developer
We’ve made improvements. Now the app can detect all notes and intervals for free within 7 days, and users can fully experience the features of this app.
Avoid
Way too expensive
Response from developer
It’s not recognizing several notes, it can detect several notes if no in-app purchase. 10 or 20$ is a good idea.
