RightRep is your AI training companion: it watches you exercise through the camera, checks your form joint by joint in real time, counts your reps, and scores every single one — all with on-device pose analysis. No wearables, no guessing. REAL-TIME FORM VALIDATION A color-coded skeleton overlay flags every monitored joint while you train: green means good, red means out of position. Priority coaching cues tell you exactly what to fix ("Chest up", "Keep elbows pinned"), and tempo checks catch rushed reps. REP COUNTING & SCORING Only complete repetitions count, and each one gets a 0–100 quality score. Watch your average form score build from session to session. BUILT FOR THE BIG LIFTS Bundled exercise profiles: squat, deadlift, bench press, bicep curl and shoulder press — plus machine scan: photograph a gym machine and AI builds a position profile for your library. MORE THAN LIFTING • GPS run tracking — distance, pace and route, works with the screen locked • Walking gait analysis — cadence, stride symmetry, foot strike, knee valgus • AI calorie tracking — photograph a meal and log the estimate • Water intake with a daily hydration goal • Meal reminders so you never miss a log SHARE YOUR WORK Record skeleton-annotated videos of your sets and share them anywhere, or post sessions to the optional community feed. YOUR DATA STAYS YOURS Pose analysis runs entirely on-device — the camera feed never leaves your phone. Media is only uploaded when you explicitly publish it. RIGHTREP PRO The free tier includes a 7-day trial of Pro features with daily quotas. RightRep Pro — monthly or yearly — lifts the daily limits, makes runs unlimited and removes ads. Subscriptions renew automatically and can be managed or cancelled anytime in Settings.

Verdict
The clearest difference is update cadence: RightRep at daily against NFP Charting's every 4 months. NFP Charting's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.
