TUNE WITHOUT PICKING A STRING Play any course. OudTuner identifies it, then shows the detected note, the target note, the frequency in hertz, and how many cents you are away. Most tuners guess the wrong string. OudTuner picks the course you actually played. When you play the right note in the wrong octave it tells you, instead of silently pointing at the wrong target. A noise gate and a confidence threshold keep the reading still while people are talking in the room. KNOW EXACTLY HOW FAR OFF YOU ARE See the note, the target, both frequencies in hertz, and a live cents readout. Flat, sharp, and in-tune are obvious. When a course settles, a haptic confirmation lets you watch the peg instead of the screen. Course progress shows what is left to tune. ARABIC AND TURKISH OUD - Arabic oud: C-C, F-F, and D-G - Turkish oud: Bolahenk and Targan - Automatic course detection across the whole preset - Optional course focus for one course at a time, for this session only - A4 calibration as shown in the app MAQAM LESSONS ON THE SCORE Open a maqam family, choose a tonic, and follow the interactive score. LISTEN, THEN PLAY Guided exercises built from maqam patterns, with a bundled oud preview at a steady tempo. Tap the score to jump to any measure. RECORD AND HEAR YOURSELF Record a practice session or a full performance. Play it back with a real waveform, 5-second skip, and rename.
