AI Rep Counter

YOUR PHONE IS A
REP COUNTER.

Kore's real-time pose detection engine tracks every joint, every rep, every angle using your phone's camera. Sub-par form? Doesn't count. Didn't go low enough on that squat challenge? Doesn't count. Reps that meet the app's movement criteria can count toward your challenge score. Camera angle, lighting, movement visibility and device performance can affect results.

Everything you need to know about the Kore fitness challenge app.

Kore is a competitive fitness challenge app that uses your phone's camera and AI to count and verify every rep you do. You join or create a squad with friends, complete daily bodyweight challenges, earn points for verified reps, and compete on a live leaderboard. No cheating — the camera sees everything.
Kore uses MediaPipe real-time pose detection via your phone's camera to track every joint and movement. Each rep is validated against strict form criteria — if your squat isn't deep enough, it doesn't count. Only full, verified reps earn you points on the leaderboard.
Kore supports 6 camera-verified exercises: squats (2 pts/rep), push-ups (3 pts/rep), lunges (2 pts/rep), jumping jacks (1 pt/rep), high knees (1 pt/rep), and plank holds (1 pt/second). Each is tracked with real-time form feedback.
Yes, Kore is completely free to download on iOS and Android. All core features — camera verification, squads, leaderboards, daily challenges, and streak tracking — are free. Kore Pro unlocks the AI body fat scanner, advanced analytics, and streak protection for rest days.
Create a squad and share your unique 6-character invite code with friends. Once everyone joins, you share a real-time leaderboard, receive the same daily fitness challenges, and can send each other dare challenges. Squad captains can set a 7-day weekly challenge schedule.
Missing a training day resets your streak to zero. Your streak is your most valuable asset — it multiplies your rank progression. Kore Pro members can activate streak protection to cover rest days without losing their streak.
