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. Lithe works with GLP-1 medications from any manufacturer and is not affiliated with, endorsed by, or sponsored by Novo Nordisk, Eli Lilly, or any drug maker. Lithe is for tracking and education only. It does not provide medical advice, diagnose conditions, treat side effects, or recommend dose changes, and it is not a substitute for your healthcare provider. Always talk with your provider about medication decisions, side effects, or health concerns.
