Needle and True Strobe
A zero-lag arc meter for quick tuning, and a strobe band that freezes only when the string is exactly in tune. A gentle tap tells you the moment it locks.
String Ladder and intonation
Tunora follows each string, moves to the next one and sums up the whole set. The Intonation Check compares the 12th-fret harmonic with the fretted note and shows which way to move the saddle.
Listens, never records
Pitch is measured in memory on your phone and the audio is discarded at once. Nothing is recorded, stored or uploaded.
