About this app

The tuner for stringed musical instruments.

Absolutely free, no annoying ads! Fully autonomous and does not require access to the Internet, nor any other additional permits.

This tuner allows to tune a variety of musical instruments: six- and seven-string guitar, bass guitar, gusli, balalaika, domra, lute, ukulele, koto, shamisen, violin, viola, cello, double-bass, kalimba, oud, banjo, guzheng, gayageum.

Lightweight application with a highly efficient detection algorithm. Less memory and CPU usage, which
makes battery life longer, Even on devices with weak CPU response still very smooth and fast, that allows for the tuning process to be precise and quick. This is not like a slideshow with a long delay, as in many other guitar tuner applications.

Minimalist and informative design does not distract, making the tuning process easy and comfortable.

High pitch detection accuracy (up to 3 cents). Works with wide range, allows to tune whole piano.

The tuner's memory has preset of more than 90 kinds of tunings for instruments listed above, including, but not limited to:
- Standard tune, as well as Drop D, Open C, Open D for a six-string guitar;
- "Russian" and "Gypsy" tune for a seven-string guitar;
- Academic diatonic tune for 15- and 17-string resonant gusli (Russian psaltery), as well as several kinds of "folk" tunes for the wing- and helmet-shaped psaltery, from 5 to 22 strings, including famous "Music Maker"/"Melody Lap Harp" ("Perepelochka").
- Academic and "folk" tunes for a balalaika;

It allows you to set a pitch frequency for A4, other than 440 Hz.

Tuner mode:
- Auto (default) - The tuner will try to determine which string is tuned at the moment, changing the color of already tuned strings.
- Fixed - quickly double-tap the button for the desired string, and the tuner will not automatically switch to another string. To return to automatic mode, press the button once again.
- Chromatic - displays piano pad to select any note to tune. It can be used to tune up any instrument, even a piano. Chromatic mode is accessible from the drop-down list with the tunes names.

Additional features:
- Playing sound tone of selected string with a single tap;
- The tone generator for tuning "by ear" (tap and hold. To switch off – short tap the same button again);
- Beep when the tuning of the selected string reaches a predetermined frequency.

Great app for violin, but I wish the notes would reorganize themselves according to instrument and strings. They are currently E, A, D, G but all violins are G, D, A, E. So it makes for a back and forth and even hit or miss experience which results in end user frustration. I would give 5 stars in a minute if this one feature / design issue was fixed!

Very very very nice!!!! Super surprised at all the settings even 432.. Wow.. Installed easily no problems on my 4 year old android phone. Works great, I love the alternative tuneing's built in such as 8,7, string guitars, mandolin, drop d etc etc etc etc. It has worked Flawlessly.. I love it!! I've used 5 others. This is the best Deleted the others this is great!! And it's free. The others came back and needed money to continue after a while. I hate that So far this is the best one I've found.

Has been my go to for violin for at least couple years now. Its accuracy has retired my old school Korg, two pitch pipes, and a turning fork. I get identical results on every phone, a Kindle Fire, and a Samsung tablet. Has always worked flawlessly, and is easy to use. Tried some others but this one won me over immediately. Free, no ads. I would pay with no hesitation for this one's quality and convenience. Highly recommended.
