Interval Health Companion

A private, low-friction recovery companion that turns clinical plans into a manageable rhythm at home.

Interval recovery companion displaying a daily rehabilitation plan

Interval helps patients follow rehabilitation plans, notice meaningful changes, and share concise progress with clinicians.

Between appointments

Recovery plans often arrive as dense printouts at a moment when attention is already stretched. Patients needed a simple answer to “what should I do today?” without turning rehabilitation into another performance metric.

We built the daily experience around a short plan, clear demonstrations, and a check-in that takes less than a minute. The product distinguishes between expected discomfort and signals that require clinical attention.

Progress without pressure

Instead of streaks, Interval shows patterns over time and makes missed days ordinary. Patients control what is shared, and clinicians receive a concise view built around change—not a stream of notifications.

Safety in the interaction

  • Every exercise preserves the clinician’s written guidance.
  • Escalation language is direct and reviewed by clinical staff.
  • Motion can be reduced without losing instructional meaning.
  • Sensitive notes remain local until the patient chooses to share.

Outcome

Pilot participants completed more of their prescribed plan and arrived at follow-ups with clearer questions. Clinicians spent less appointment time reconstructing the weeks between visits.
