Tonic - Tuner and Music Theory

Tuner Metronome & Chords

$4.99 · Designed for iPad. Not verified for macOS.

A multi-instrument tuner, metronome, and a full band to play with — plus lessons, drills, scales, chords, and music theory. One purchase, everything unlocked. No ads. Tonic is an ad-free instrument tuner that is also a pretty darn good music practice companion. It is priced once and yours to keep. No subscriptions, no ads, no account, no data collection. Everything runs on your device and works fully offline. I think that's the way it should be. So if you just want a good tuner, with all of the tunings, and a practice reference/chord finder/music theory companion without creating an account, paying for a subscription, paying for upgrades, trying to close out pesky ads, or connecting your social media, this is for you. I wanted it myself, so I built it for myself, and maybe you want it as well. What's included: TUNER Chromatic tuner Guitar (7 tunings, plus 7-, 8-, and 12-string), Bass (5 tunings), Ukulele, Mandolin, Violin, Banjo, and a dedicated Vocals mode. Every tuning unlocked, nothing gated behind a paywall Create and save your own custom guitar tunings All-strings view to check every string at a glance, or single-note focus Reference tone (drone) to tune by ear Adjustable reference pitch (A4, for orchestral players who tune away from 440Hz) Adjustable mic sensitivity for noisy rooms or quiet instruments Optional haptic feedback the moment you're in tune METRONOME Sample-accurate timing, scheduled through the audio engine. KEY/CHORD FINDER (Beta) Listens live and identifies the key and chord you're playing Start/stop control with a scrollable chart of every chord played, so you can plot out a song and play along Works best on clean, single-instrument audio, like any chroma-based chord recognizer RECORDER/LOOPER Record practice takes or song ideas, with a metronome guide click while you record History with folders and search Loop a specific section of a recording to drill a tricky passage Run offline chord/key analysis on any saved recording SONGS Build a chord progression by key and tempo, then save it with lyrics or notes - a real sketchpad for songwriting, not just a scratch pad EAR TRAINING Interval and chord-quality recognition drills; a practice tool to help with learning music by ear. RESOURCES a full music theory & reference library Interactive scales, chords, and note maps for every instrument in the app, plus Piano Guitar Triad Finder: every close-position triad inversion across any three adjacent strings, for any tuning Open Chords and CAGED chart, Capo chart Piano chord inversion finder Position View: see a scale one hand-position at a time instead of the whole neck at once Interval-label overlay: see scale degrees (R, b3, 5...) instead of note names An interactive Circle of Fifths: tap any key to see its signature and diatonic chords Diatonic chords, all-key chord tables, an interactive chord formula explorer, and common progressions that transpose live into any key, plus a progression builder Reading sheet music: clefs, accidentals, note durations, intervals, time and key signatures, dynamics and articulation; all drawn accurately, not just described PRIVACY No accounts, no analytics, no ads, no network connection. The microphone is processed in real time and never saved unless you explicitly record. And even then, it stays on your device unless you choose to share the file you saved yourself outside of the app.

A steadier tuner • The needle glides and settles on the note instead of jumping with every reading — on guitar and everything else • Bright, quick-fading strings like a banjo's no longer swing between high and low • "In tune" holds steady right at the edge instead of flickering Banjo • Drills show your picking-hand finger — T, I or M — the way banjo tab is written • New: Clawhammer & Old-Time lessons — the bum-ditty, drop thumb, and Double C and Sawmill tunings — with a Clawhammer drill to practice them Backing Band • A much better electric guitar: played through real recorded speaker cabinets and double-tracked the way records are, for a fuller, warmer sound — and no two strums alike
