Injection management, done properly. PinTrax is a private tracker for insulin, GLP-1s, and the compounds you reconstitute: site rotation on a body map, dose schedules, vial math, and a reconstitution calculator, all on your phone. This list gets exactly two emails before launch: one when the Android beta opens, one when the app ships. After that, occasional deep dives on reconstitution math, reading CoAs, and rotation done right.
