CoreLoop is a movement investigation app.

That thing that keeps coming back — the wrist that aches at the bottom of a push-up, the knee that gives out on stairs, the shoulder that jams at the top of a pull-up. Everything you've tried was aimed at where it hurts. CoreLoop investigates what's driving it.

CoreLoop is not an answer bot. It doesn't hand you a stretch and wish you luck. You talk to an AI investigator — out loud or by text — about what your body does under load, at the exact moment it fails. Together you form a hypothesis about the movement or structure behind it. Then you test one adjustment, and only one. You come back and report what happened. The loop tightens. Over time, the pattern shows.

HOW IT WORKS
Signal — describe what happens and exactly when.
Hypothesis — your investigator forms one, in plain language, and tells you what would confirm or rule it out.
Adjustment — one change to test in your next session.
Outcome — you report back. The investigation updates, holds, or closes.

FOUR INVESTIGATORS
Ethan, Marcus, Sofia and Aria. Each has a voice. Pick the one you want to think with. Interrupt any time.

YOUR PORTFOLIO
Every investigation is kept with its current hypothesis, what's being tested, and every signal linked to it. Pull a full read on demand.

BUILT FOR ATHLETES AND MOVERS
Lifting, pickleball, tennis, racquetball, Pilates, cycling, running, the gym. If your body does it repeatedly and something is off, it's an investigation.

CoreLoop asks questions. It works with what you can feel and report. It is not a medical service and does not diagnose or treat any condition. If something is injured, see a professional.

Come in curious. Tighten the loop. Reveal the pattern.

Free during beta. Microphone access is used only when you start a voice session.
