Repsight
Read full descriptionHide full description
Build a personal circuit and log actual completed sets without opening the camera. Saved progress keeps your place across app launches. HOW IT WORKS 1. Open Circuits, name your plan, add up to six exercises and choose one to eight rounds. Targets are your own planning values. 2. Start the circuit log. Enter actual reps, or seconds for a plank hold, then record the set. Skip remains distinct from a recorded zero. 3. Resume saved circuits, review and share the manual record, repeat the plan as a new circuit, or delete a log after confirmation. Existing camera rep counting, exercise modes, multi-set sessions, coaching, workout history, insights and settings remain available. WHAT TO KNOW Manual records do not measure form, calories, tempo or fitness. Camera-counted history remains separate and unchanged. Targets are not prescriptions; choose activity appropriate for you and rest as needed. Repeating a circuit starts a fresh unrecorded log. iPhone and iPad.

Don't fall for the fake-out. 20+ experiments, each one designed to trick your attention. YOUR CAMERA BECOMES THE GAME No controller. Just your hands. Reach the green zone and stay out of the red in Color Call. Switch sides as fast as you can in Side Switch. Freeze your hand dead still in Move & Hold. Memorize a pattern and reach it back in Sequence Reach. TRAIN YOUR EYES Go / No-Go: tap on green, hold on red, and don't bite. Peripheral Flash: catch what blinks at the edge without moving your eyes. Plus Reaction Arena, Number Grid, Precision Tracking and Stroop Focus. CHALLENGE YOUR FRIENDS Every run gets a challenge code. Send it, and your friend plays the exact same round. Same experiment, same difficulty, no excuses. THE IMPOSSIBLE ROUND A new near-impossible challenge every week. Almost nobody clears it. FEELS DIFFERENT EVERY DAY New Today, Hard Mode, Mystery Experiments and a daily Community Challenge everyone plays together. YOU VS.
