A coach beside you, between lessons.
Real-time intonation, rhythm, and tone feedback for school band wind players — running entirely on your iPhone, with no recordings leaving the device.
Coming soon to the App StoreYIN-based pitch detection on-device: see exactly how many cents above or below the target you are, and whether you're rushing or dragging the beat.
The timer only counts while you are actually playing. Take a break and it pauses on its own. Streaks and weekly progress build automatically.
One tap exports a clean weekly summary — minutes per day, average intonation, week-over-week improvement — to share with your band director.
The coach reads your week and proposes a specific next session. Powered by Apple's on-device Foundation Models on iOS 26, with a rule-based fallback elsewhere.
Flute, Bb Clarinet, Alto Saxophone, Bb Trumpet, and Trombone — each with its own transposition, comfortable range, and starter exercises.
No login required. No analytics SDKs. No tracking. Free use includes one instrument and one session per day; FirstChair Plus unlocks everything.
FirstChair was designed for middle-school and high-school students who already take lessons or play in band — and for the parents who want to know that practice is actually happening. The exercises are in the keys your band director actually assigns, and the report is ready to send on Sunday night.
