PracticeBell

PracticeBell is a local-first music practice lab for musicians who want more than a basic timer. Plan what to practice, keep the metronome moving, tune by ear or microphone, track repertoire, review progress, and leave each session with a clear next step. PLAN EACH SESSION - Plan Lab builds a time-boxed practice plan from your pieces, recent sessions, BPM targets, goals, and deadlines - Session blocks cover arrival, warmup, focused isolation, tempo ladder work, and review - Watchlist cards flag overdue pieces, wide tempo gaps, recent struggle sessions, and deadline pressure - Share or copy the plan when you want a simple lesson or rehearsal note PRACTICE WITH MUSICAL TOOLS - Metronome with time signatures, subdivisions, accents, tap tempo, and multiple click voices - Tempo Ramp trainer for gradual speed work - Gap Trainer for internal time and rhythmic recovery - Drone Reference for sustained pitch and intonation practice - Chromatic Tuner with on-device microphone analysis - Tempo Programs for section-by-section tempo maps TRACK REAL PROGRESS - Piece library with composer, instrument, key, target BPM, status, notes, and session history - BPM progress charts for repertoire work - Daily minutes, streaks, heatmap, top pieces, instrument breakdown, and session quality charts - Goals for daily minutes, weekly minutes, session count, deadline pieces, and BPM targets - Session history with search, filters, sorting, CSV export, and per-piece PDF logs REFERENCE BUILT IN - Offline scale and key reference with major, natural minor, harmonic minor, melodic minor, and circle-of-fifths tools - Interval reference for ear-training vocabulary - Tempo term reference from largo to prestissimo - Tuning reference and A4 calibration support - Offline reference pack with ten high-resolution practice sheets for deliberate practice, tempo ladders, rhythm grids, key-circle warmups, session review, recital readiness, sight-reading, technique rotation, ensemble prep, and goals PRIVATE BY DESIGN PracticeBell stores practice records locally. It does not require an account, does not use analytics SDKs, does not include advertising SDKs, and does not send practice logs or microphone audio to a developer server. Microphone access is used only when you open the chromatic tuner, and audio is analyzed live on device. PracticeBell is built for daily players, teachers, ensemble musicians, self-guided learners, and anyone who wants practice time to turn into visible progress.
