SIX WAYS TO MAKE IT YOURS • Studio: a calm, clear interface in warm ivory and forest green, included free. • Morning Garden: impressionist brushstrokes and soft morning light. • Mountain Stillness: ink-wash mountains, rice-paper texture and a touch of vermilion. • Little Studio: hand-drawn instruments and a warm wooden dial. • Sakura Practice: an original anime character, cherry blossoms and a soft window-lit practice space. • Kitten Afternoon: a cozy cat by a sunlit window, cream panels and sage-green details. MAKE YOUR COLLECTION YOURS Choose an individual theme, or get the All Themes Pack to unlock every current and future theme with one non-consumable purchase. No subscription. Existing individual purchases stay valid. Restore purchases with your Apple Account. Previewing every theme and all tuning features remain free. ONE TUNER, MANY INSTRUMENTS Choose guitar, ukulele, bass, violin, viola, cello, double bass, mandolin or banjo. A chromatic mode identifies notes for other instruments too. Search the instrument library and return quickly to recent instruments. TUNE WITH A CLEAR VIEW See the detected note, octave, frequency and pitch deviation in cents. Tune one note at a time with automatic detection, or tap a string to lock the target. Presets include guitar standard and Drop D, plus high-G and low-G ukulele. Adjust the A4 reference from 430 to 450 Hz. Optional haptic feedback confirms a stable, in-tune note. PRACTICE WITH A FREE METRONOME Switch from tuning to rhythm practice right on the home screen. Set 30–240 BPM with the slider or step buttons, or tap your own tempo. Choose 2/4, 3/4, 4/4, 5/4, 6/8, 7/8, 9/8 or 12/8; use one to four clicks per beat, optional first-beat accents and adjustable volume. A moving pendulum and beat indicators follow the rhythm in your current theme. Settings are remembered. In /8 meters, BPM counts eighth notes. The metronome does not require microphone access, and stops when you leave the screen or put the app in the background. YOUR SOUND STAYS WITH YOU Audio is processed on your device. Recordings are not saved or uploaded. Microphone access is required for live tuning; no account is needed. AVAILABLE IN 10 LANGUAGES English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, French, German, Brazilian Portuguese and Italian.
