Tonagi is the tuner that becomes a practice partner: it plays the reference beside you like an accompanying piano, follows your practice step by step, and shows you whether you are actually improving.
Made by a musician, for musicians. Launch: autumn 2026, on the App Store; in beta with musicians now.

Fast facts
- iPhone and iPad. 15 interface languages.
- 15 tuning systems built in, plus custom temperaments. Concert pitch from 400 to 470 Hz.
- Two free views of the tuner: the tone thread (every note in time) and the tone orbit (twelve notes around a ring, one octave per circle). Four tolerance levels — Wide, Medium, Fine and Minimal (±15, ±10, ±5 and ±2 cents).
- Recordings scored 0–100 note by note (the attack is left out), with credit that grows the closer each note settles — and a per-note profile of what settles and what drifts.
- Sequences hold a reference chord under your playing — advanced with the arrows or a Bluetooth pedal, or by the metronome in Guided and Accompaniment — in Loop or Mirror.
- Routines chain the tuner, the metronome, the tone generator and a sequence in phases — each ends after minutes, passes or bars, or when you move on — and can start from any phase. The metronome adds Inner pulse, Acceleration and Polyrhythm.
- Free tuner in equal temperament, everyday metronome, and three sequences of up to eight steps and three routines of three phases; Premium at €2.99/month or €14.99/year — both with a 7‑day free trial — or €34.99 once, for life.
- Audio stays on the player's device and in their personal iCloud backup — nothing is sent to us. No accounts in the app, no ads, no analytics.
- Made in Lisbon, Portugal.
Name and marks
Tonagi joins Tone (the pitch), Tonari (Japanese, "by your side") and Nagi (凪 — the sea falling still as the wind stops). Please write it with a capital T only: "Tonagi". The wordmark sets "To" in light neutral and "nagi" in green; the symbol may be used on its own. Typography is the system font — SF on Apple platforms — light for body text, semibold for emphasis; no webfont.
