Frequently asked questions

What makes One Click Tuner unique?: The two most common methods of tuner visualization are a needle or a scrolling line, both of which represent the distance in cents between the note being played and your target note.
Non-digital instruments create sound with enough frequency variability that tuners need to "smooth" the frequency so that the needle/line doesn't jump around too much. One Click Tuner is unique in that it displays the entire distribution of frequencies.
What instruments can One Click Tuner tune?: All of them! Most of our users are guitar players, but One Click Tuner also works for basses, banjos, mandolins, etc.
Are there ads?: No. Never.
Do you collect any personal information from me?: No. Never.
Will anything pop up at me (in-app purchase, etc.)?: No, we don't like that stuff either.

If you’re a minimalist, and you want the most stripped down and effective tuner app available, this is it.

I'd like to take the opportunity to again express my appreciation for the One Click app. Its simple answer to a common real-world request is uncommonly elegant amongst the noisy offerings of the current digital climate. Well done.

It costs a less than most cups of coffee, and the clean, intuitive, no-nonsense, ad-free experience makes it immediately apparent that it was money well-spent.
