Tonagi: Tuner Practice Studio
Intonation, drone, metronome
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Tonagi is a precision tuner that becomes a practice partner: it plays the reference beside you, like a piano playing along, and shows you in numbers how you improve.
HEAR WHERE EVERY NOTE LANDS
• A chromatic tuner precise to a fraction of a cent, in 15 temperaments — equal, just, Pythagorean, Werckmeister and more — with reference pitch from 400 to 470 Hz
• Play against a drone: one note or a whole chord, in the tuning you choose
• See at a glance which notes drift, and which way
PRACTICE WITH A PARTNER, HANDS-FREE
• Turn any scale, arpeggio or passage into a sequence — the app plays each step beside you
• Advance with a Bluetooth pedal and keep your hands on the instrument
• Build routines that chain tuner, drone, sequences and metronome into one session
• A steady metronome — and, in Premium, compound and mixed meters, rhythmic figures, acceleration and polyrhythms
WATCH YOURSELF IMPROVE — PREMIUM
• Record your practice and get a 0–100 score for how close each note lands
• Group recordings by piece or passage and watch them get better over the weeks
• Share a PDF report with your teacher
PRIVATE BY DESIGN
• Your sound is analyzed on your device — nothing is sent to us
• No accounts, no ads, no analytics; works offline; optional sync through your own iCloud
FOR EVERY INSTRUMENT WHERE PITCH IS IN YOUR HANDS
Strings, woodwinds, brass and voice. Available in 15 languages.
Tonagi is free to use as a precise chromatic tuner with a basic metronome — and sequences and routines open on the free plan too, up to three of each, so you can really try them. Premium opens everything: the remaining 14 temperaments, unlimited sequences and routines, the advanced metronome, Progress and PDF/iCloud — subscribe monthly or yearly with 7 days free, or make a single lifetime purchase.

• More reliable iCloud: once a day each device checks that its sequences are in iCloud and sends whatever is missing. Settings ▸ Sync shows how many are there.
• Organizing folders on one device no longer messes up the others.
• Repeated copies of the same sequence merge into one.
• The tone orbit moves more smoothly.
• Routines: the stage shows next time’s tempo.
• Refreshed tips and small fixes.
