Lithe: GLP-1 Weight Tracker

Lithe is a GLP-1 tracker for weight-loss shots and pills. Log every dose, weigh-in, and side effect, and see your whole journey in one calm, simple place.

Made for people on semaglutide or tirzepatide medications — injections and oral doses alike.

SHOTS & PILLS, ONE TRACKER Log a weekly injection or a daily pill in a couple of taps. Oral doses get a simple check-in grid, so one glance shows your streak.

ROTATE INJECTION SITES Pick from a body map and let Lithe suggest the next site — spread your doses out and keep a clear record of where each one went.

SEE YOUR MEDICATION LEVEL An estimated medication-level curve shows how each dose builds and tapers between shots, based on published half-life data.

WEIGHT TREND & GOAL Chart every weigh-in, set a goal and pace, and follow a projection line toward it.

SIDE EFFECTS & DAILY HABITS Log nausea, fatigue and more by severity, and keep up protein, fiber, water and activity alongside your medication.

REMINDERS SO YOU DON'T MISS A DOSE Set shot or pill reminders and a dose time, and Lithe keeps a countdown to your next dose.
