4DEYE DTx
The prescription continues at home
Rehab stops at the hospital door, leaving only “it feels a bit better.” 4DEYE DTx fills that gap with data.

Not an exercise app
Exercise should come with a prescription
Like a drug with a set dose, exercise is prescribed within a trial-validated range. That is how we could prove the effect in numbers — the results on this page.
Exercise app vs. therapeutic
- A typical exercise app
- A fixed programme. You pick the target and judge results by feel.
- 4DEYE DTx
- Prescribed for the compensation measured in each patient, within a range proven in a confirmatory trial.
Prescription to rehab
One patient, one unbroken record
Prescribe
Exercise comes straight from the measurement
It picks the right mix for that joint from hundreds of exercises, within the range validated in the confirmatory trial.
Deliver
Sent to the patient’s phone
The approved prescription goes straight to the patient app. No paper handouts.
Perform
The camera scores each movement
At home, the phone camera scores posture accuracy. Patients also log pain, medication and more daily.
Track
The patient sees their own data
Patients see weekly progress and therapist comments.
Manage
The dashboard shows who has fallen behind
Adherence, pain and missed sessions at a glance. Low adherence triggers a messenger reminder; an AI summary preps each consultation.
