A small mobile app I built for friends and family on GLP-1 medication. It keeps their shots, weigh-ins and workouts in one place, suggests the next injection site, and turns the whole journey into trends they can actually read.

Why it exists
People I care about started tirzepatide and asked the same questions every week: when is the next shot, where did the last one go, and is any of this working? The notes app wasn’t cutting it, and the medical apps felt like homework.
Everything in one log
Every entry is a shot, a weigh-in, a workout, a measurement, a photo or a note, each with its own colour. A shot records the dose and the injection site, and the app suggests the next site so they rotate properly. A workout records the type and the length, and nudges toward whatever is up next. It all lands on one calendar.
Trends you can read
The trends screen says it in a sentence: how long they’ve been at it, how much is gone, the pace, and when they’ll reach the goal at that pace. Charts for weight and workouts sit beneath, and every shot is listed with its dose, site and how it felt.
Made to feel good
Losing weight on medication is a long, unglamorous routine, so the app is deliberately playful: a sticker-book look with chunky type, pastel paper, black outlines and little surprises along the way. A countdown to the next shot is the hero of the home screen, because that is the question people open it to answer.
