Akort+ needs the microphone to measure pitch. On iPhone, enable it under Settings → Akort+ → Microphone. On Android, under Settings → Apps → Akort+ → Permissions → Microphone. On Mac, check Akort+ under System Settings → Privacy & Security → Microphone. In the browser version, grant the microphone from the lock icon in the address bar. If another app is holding the microphone exclusively, quit it and try again.
You do not. Akort+ hears what you play and finds the nearest pitch itself. That is also why non-standard tunings work.
It measures against the 53-comma Arel-Ezgi-Uzdilek system of Turkish makam music, naming the pitches that fall between the Western semitones directly — the ones used on the bağlama, oud, kanun, ney and tanbur. Chromatic mode is standard twelve-tone equal temperament.
In makam mode every pitch is named against the nearest natural. The same sound can be spelled differently in traditional notation; the measured pitch is identical, only the spelling differs.
If you have retuned your instrument but still think in your usual positions, open Settings → Transposition and pick the note you play and the pitch it now sounds as. If your D string now sounds B, set "D = B"; hearing B, the app shows D. Only the names change — the cents reading still measures the pitch you are actually sounding.
Adjust the A4 reference between 415 and 466 Hz under Settings → Reference pitch.
Set the in-tune range to ±3, ±5 or ±10 cents under Settings → In-tune range.
