Smarter injection site tracking

A holistic improvement to how injection sites are logged, suggested, and viewed.

Planned:

• Visual body map to tap-to-log injection sites

• Custom sites for spots not on the default list (e.g. lats for IM)

• Per-compound preferences for which sites are allowed (your peptides and testosterone shouldn't share the same rotation pool)

• Per-compound injection history shown right when you're picking a site (no more drilling into the compound to check)

• Last injection site visible on upcoming dose cards on Today (see where you went last time BEFORE you log)

• Show/hide specific sites if you never use them (e.g. arms, thighs)

• Reserve a site for a specific compound

• Exclude a site from the rotation

Comment with anything else that would help you log faster and rotate smarter.
