A wearable sensor and app that learns what correct exercise form looks like — then tells patients, in real time, whether they're doing it right. Physios finally see what happens after the patient leaves the room.
Typical adherence to prescribed rehab exercises — patients are largely unsupervised and unsure if they're doing it right.
Added annual cost per patient when recovery is delayed by poor exercise adherence.
A significant, recurring source of lost income for physiotherapists — patients who don't recover on schedule mean fewer sessions, referrals and outcomes to point to.
The physio sets the standard once. The patient gets feedback every rep, at home. Nobody has to guess anymore.
During a supervised session, the physio prescribes an exercise while the patient wears the sensor. ExerWatch's AI learns what "correct" looks like — personalised to that patient.
The patient wears the strap and opens the app unsupervised. No camera, no clinic visit required.
Green means correct, amber means partial, coral means the exercise wasn't done correctly or the range of motion wasn't complete — every single rep, in real time.
Objective adherence and technique reports land in the physio's app between visits — a feedback loop that doesn't exist today.
Prescribe once, then see exactly how patients are doing between visits — without relying on self-reported diaries.
Know you're doing it right, without a clinician in the room. No camera pointed at your living room.
Video tools like Kemtai and Sword Health need a clear line of sight and raise privacy concerns at home. Consumer wearables like Apple Watch or Whoop track movement — but none of them can learn a prescribed exercise and grade its form.
| Approach | Judges exercise form | Works unsupervised at home | No camera in the room |
|---|---|---|---|
| ExerWatch | Yes | Yes | Yes |
| Self-reported diaries / apps | — no verification | Yes | Yes |
| Video-based coaching (e.g. Kemtai, Sword Health) | Yes, angle-dependent | Needs clear sightline | Camera required |
| Consumer wearables (Apple Watch, Garmin, Whoop) | Not built for this | Yes | Yes |
ExerWatch is pre-launch — currently piloting with real physios and real patients ahead of a 2026 launch.
Piloting exercise adherence and form monitoring for patients recovering from knee surgery in the rehabilitation ward.
Physios comparing ExerWatch's detection and UI against their current technology, in daily practice.
