site-rotation injection symptom-correlation
PRD v2.0 defines site rotation as a pillar, not a side feature.
Why? Because users need two outcomes at the same time:
- avoid repeating the same location,
- find a pattern that minimizes discomfort and side effects.
Steadiva supports this with:
- clear site history in timeline,
- recommended next site hint on Home,
- report-level summaries for follow-ups.
The app does not claim a universal “best site.” It helps each user find their own stable pattern.
