Custom Tuner vs Rig Tuner

Custom Tuner helps you tune wind instruments, strings and your voice. Beyond showing your current pitch deviation, it records which notes tend to be sharp or flat so you can review your practice. ■ Tuner • Note name, frequency and deviation in cents in real time • A ±50-cent meter with Flat, Sharp and In tune guidance • The current note on a staff, with automatic treble/bass clef switching • Written pitch for transposing instruments in B-flat, E-flat, F and more • A4 reference pitch from 410–480 Hz, with 415/432/440/442 Hz presets • Choose C D E, Do Re Mi or German note names (B/H) ■ Trace • A graph of the last 15 seconds of pitch movement: deviation from the note or pitch height ■ Tone • Sustain reference tones across all 12 notes in octaves 1–7 to tune by ear ■ Intonation tendencies (Records) • Hold a note for at least one second to automatically log its pitch deviation • A keyboard-shaped chart shows which notes tend to be sharp or flat, with written-pitch display for transposing instruments too ■ Pro (one-time in-app purchase, supports Family Sharing) • Review intonation tendencies over 7 days, 30 days or all time, with graphs of daily changes • Chord drones: sustain a fifth, major triad, minor triad or octave to tune within a chord • Switch between just intonation and equal temperament while the drone plays to compare beats by ear • An organ-like tone rich in harmonics makes tuning differences easier to hear as beats • Connect headphones to measure your pitch while the drone plays. For the third of a chord, the meter centers on the just-intonation target of −14 cents • Long-tone practice: 4-, 8- and 12-second exercises score pitch deviation and fluctuation. Set personal bests for each note • Explore harmonics: spectrum, levels of harmonics 1–10, spectral centroid, odd/even harmonic ratio and harmonics-to-noise ratio • Record practice and listen back alongside the pitch graph, up to 5 minutes per recording • Before purchasing, preview the rich harmonic tone and compare just intonation with equal temperament ■ Privacy Microphone audio is analyzed on your device.
