ADR 0001 — v1 foundations

Status: Accepted (2026-10-28)

Decisions

1. Platform: Flutter, Android only.
2. Modes: A global Stretching / Workout switch that changes design, content and everything else.
3. Content: A large bundled Exercise Library; users create all Plans themselves (no built-in Plans).
4. Data: Offline only, local on-device storage, no accounts.
5. Sessions: Guided Player (timers, rest countdown, cues) rather than a checklist.
6. History: Simple log (date, Plan, duration) + Streak.
7. Visuals: Simple animations are desired, but may be deferred past v1.
8. Scheduling / reminders: Not in v1.

Consequences

• No backend; all persistence is a local database on the device.
• The Exercise Library must be bundled in the APK, so its size (incl. images) matters.
