Everything in one place
Five things, done properly — so tracking takes seconds and the useful part is what you learn from it.
Set your schedule once. Holt reminds you on dose day, shows a Live Activity when it’s time, and keeps a clean history of every shot, pill and injection site.

Photograph your plate or scan a food to estimate calories and protein — because on a GLP-1, eating enough of the right things matters as much as eating less.

Note nausea, fatigue or appetite changes in a tap. Holt lines them up against your dose days so patterns are easy to spot — and easy to talk about with your doctor.

Set a weight goal and watch the trend, not the daily noise. Weight history and milestones in one calm view.

Quick-add water from a home-screen widget and keep the small daily habits that make a GLP-1 week go smoothly.
Also: Apple Health sync, a doctor-visit report and home-screen widgets.
Our approach
GLP-1 medications quiet your appetite. That’s the point — but it also makes it easy to under-eat protein, fiber and water. Holt keeps those front and center, gently, without calorie shaming.
