PT Exercise App

A React Native app for patients to manage and run their own physical therapy exercise routines. Fully offline, no accounts, no backend.

Scope

• Users: patients only, self-guided (no clinician-facing side)
• Content: illustrated steps + timers/reps counters (no video, no camera-based rep tracking)
• Scale: small — single clinic, hundreds of patients
• Data: informal/wellness-tier, not HIPAA — no special compliance handling required
• Connectivity: fully offline, no accounts or backend
• Team: solo dev / small team, ship fast

Structure

docs/
  SYSTEM_DESIGN.md   — full architecture, schema, and key design decisions
db/
  schema.sql         — SQLite schema (exercises, routines, routine_steps, session_logs)

See docs/SYSTEM_DESIGN.md for the full design writeup, including the two approaches considered for session timer/cue reliability (the riskiest piece) and the reasoning behind the schema and storage choices.

Status

Design phase — architecture and schema defined, not yet implemented.
