Features

The note you play is heard through the microphone and analysed on this device in real time; the sound is never recorded and never sent anywhere. From guitar to bağlama, with built-in and custom tunings.

Key features

Instruments and tunings
Guitar (standard, Drop D, half step down, whole step down, DADGAD, Open G, Open D, Drop C), bass guitar (4 and 5 strings), ukulele (standard, low G, baritone, D tuning), violin, viola, cello and bağlama (bağlama düzeni, bozuk düzen).
Chromatic mode
Recognises any note without choosing an instrument.
String detection
The string being played is found automatically; a string can also be locked. The app shows whether it is flat or sharp and whether to tighten or loosen it; strings that are in tune are marked.
Custom tunings
The number of strings and the note of each string are chosen by the user.
Reference
The A4 frequency is changed in 1 Hz steps (e.g. 432 or 442 Hz). Tapping a string plays its reference tone, so tuning by ear works without a microphone.
Display
Note names and sharps or flats are chosen; the tolerance is adjustable.

Devices and browsers

  • The microphone is only on when the user turns it on, and it turns off when the app goes to the background.
  • On phones the gauge and strings share one screen with settings in a bottom panel; on wide screens the settings are at the side.
