REPJOY
Feel Every Squat Rep
Only for iPhone
Free
iPhone
Turn every squat into tactile play. Feel depth, control, and holds through sound and haptics, then challenge your weekly Local League.
YOUR BODY IS THE CONTROLLER.
REPJOY turns every squat into tactile, audible play. Put your iPhone securely in a front or side thigh pocket—or a stable thigh band—and start moving. The app tunes itself from your first reps and responds with sound, haptics, and short coaching cues.
FEEL EVERY PHASE
• Feedback builds as you descend.
• A clear cue marks the bottom and your change of direction.
• Guided hold reps tell you when to hold and when to rise with control.
• A crisp hit confirms each completed rep.
COUNT REPS. UNDERSTAND MOVEMENT.
REPJOY shows completed reps beside Q, a personal movement score shaped by depth, control, and hold time. Q helps you compare your own sessions; it is not a medical posture assessment.
BUILT FOR QUICK ROUTINES
Choose 7, 14, or 21 reps per set. Automatic tuning happens inside the workout, so there is no separate calibration ritual. Your completed sessions become simple trends for reps, Q, active days, and streaks.
YOUR LOCAL LEAGUE
Optionally sign in with Apple, choose a nickname and a broad region, and compare weekly Q Scores with real participants. REP GHOST targets are clearly labeled practice benchmarks, not people. REPJOY never asks for precise GPS location.
PRIVATE BY DESIGN
• No account required for workouts
• No camera or wearable required
• Raw motion signals are processed on your iPhone
• Workout history stays on your device
• Only signed-in Local League users sync limited workout summaries
• No advertising, in-app purchase, or subscription in version 1.2
Exercise within your ability and stop if you feel pain, dizziness, or unusual discomfort. REPJOY is a fitness companion and does not provide medical diagnosis or treatment.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
REPJOY now starts with a clearer countdown and smarter automatic tuning. Guided holds add short, well-timed coaching cues, while the new Local League lets you compare weekly Q Scores in a broad region you choose. We also refined haptics, workout summaries, and account deletion.
