Built for how people actually train
Most fitness apps count seconds. RhythmFit counts beats — across execution, learning, and lifestyle.
Rhythm Execution
Lock HIIT intervals, tempo strength, jump rope, cycling, and running into a precision metronome (40–220 BPM). High/low alternating tones train left/right symmetry.
HIIT · Tabata · Tempo Strength · Running · Jump Rope
Movement Learning
Block-level safety notes and technique cues are spoken before each phase, then a Got-It confirmation hands you off to the rhythm engine. Works for squats, deadlifts, tai chi, yoga, and rehab.
Squat · Deadlift · Bench · Tai Chi · Yoga · Rehab
Life Rhythm
Box breathing, coherent 5.5, belly breathing, scenario meditations, and office stretches — all paced by the same beat engine that drives your training sessions.
Box · Belly · 5.5 · Meditation · Office Stretch
Everything you need to train on the beat
Built for runners, lifters, breath-workers, and anyone tired of workouts that ignore rhythm.
Precision Metronome
40–220 BPM with alternating high/low tones. Embedded countdowns in the final seconds of each block — no break in flow.
AI Workout Coach
Tell Claude what you want — "30 minutes upper body, no equipment, intermediate" — and get a custom workout in seconds. Import from photos, PDFs, text, or video links.
Voice Coach + Siri
Pre-block safety + technique notes, in-block reminders, and next-phase previews. "Hey Siri, pause RhythmFit." Ten Siri commands work hands-free — pause, skip, tempo, live status — with AirPods supported.
Apple Watch on Your Wrist
Live phase, time, BPM, and color. Haptic metronome turns your watch into the beat. Pro adds live heart rate, automatic rep counting, and technique cues.
Your Music, Mixed Right
Play your Apple Music library during any workout. It dips when the coach speaks, goes quiet for countdowns, and pauses and resumes with the session.
50+ Built-in Templates
Cardio HIIT, running, cycling, strength circuits, tempo strength (3-1-3 cadence), shadow boxing, mobility, breathing, scenario meditations, office stretches, plyometrics.
Zero-Friction Tools
Standalone Timer and Metronome — open and use in seconds. Tap tempo, presets, torch sync, sound + flash + vibrate alerts.
Share Workouts, Not Audio
Send a rhythmfit.me/w/… link to anyone. Recipients get a full preview on the web and can import in one tap. Static share cards never contain licensed audio.
Free forever. Pro when you want more.
New users get a 7-day welcome trial with everything unlocked. After that, Free stays generous and Pro removes every limit.
