Lighter is the dead-simple GLP-1 tracker. Log every shot in two taps, see your estimated medication level, and make every dose count — without the overwhelm. You're spending a fortune on the most important thing you've done for your body. Lighter makes sure none of it slips through the cracks. Log your dose, your injection site, and how you felt in seconds — and finally see the rhythm of your GLP-1 journey on one calm timeline. Works with every major GLP-1 and peptide — semaglutide, tirzepatide, retatrutide, dulaglutide, liraglutide, orforglipron, compounded, weekly or daily. TRACK EVERY SHOT IN TWO TAPS • Log injections or pills in seconds — dose, injection site, and how you felt • Rotate injection sites on a simple body map • Set shot-day reminders and a next-dose countdown, so you never wonder "did I take it?" SEE YOUR MEDICATION LEVEL • Watch your estimated medication level rise and fall between doses • Modeled per medication, so you can see where you are in your dosing window • An informational estimate — not medical advice KNOW YOUR SIDE EFFECTS • Log nausea, fatigue, food noise, and more — on a panel you customize • Track severity and spot your own patterns by dose and site • Keep clear notes to talk through with your healthcare provider SEE YOUR PROGRESS • Simple weight tracking and trends • A clean daily view of your doses, weight, and side effects — all in one place BUILT TO STAY LIGHT • Start instantly — no account required • Private by default. We never sell your data. • Fast, calm, and clear — the essentials done well, not twenty features you'll never open WHY LIGHTER Most GLP-1 apps bury you in food scanners, macros, and dashboards until tracking feels like another job. Lighter does the opposite. It keeps you to what actually matters — your dose, your patterns, and your progress — so staying consistent feels effortless.
