Your titration schedule deserves better than a reminder app.
Track doses, weight, and levels — together.
Doseline tracks your GLP-1 medication with real pharmacokinetic modeling, weight correlation charts, and titration schedule awareness. Built for semaglutide, tirzepatide, and every GLP-1 on the market.
The problem
Most apps track one medication. Your doctor just added a second.
You started with Wegovy and a simple reminder app. Then came metformin. Now you're logging weight in one app, doses in another, and your titration schedule is a screenshot from your clinic's portal. None of these tools talk to each other, and none of them show you what's actually happening between injections.
What GLP-1 users get
Built around your protocol.
Weight tracking with dose context
See your weight trend alongside your dose history. Know whether a plateau is a dose issue or a timing one — not just a number on a scale.
Daily weight · 7/14/30-day trends · Dose overlay · Goal tracking
Medication level charts
Real pharmacokinetic modeling shows your estimated serum concentration between injections. See your peaks, troughs, and steady-state accumulation.
Semaglutide · Tirzepatide · Liraglutide · Dulaglutide · 10+ more
Multi-medication protocols
GLP-1 plus metformin. Or a GLP-1/GIP dual agonist with a B12 supplement. Track your full protocol, not just one drug.
Each compound gets its own PK curve · schedule · reminders
Smart reminders with titration awareness
Doseline knows your titration schedule. Reminders adjust as your dose changes — no manual updates every 4 weeks.
Wegovy 16-week · Mounjaro 28-week · Custom schedules
Injection site rotation
Visual body map with rotation history. Log where you injected, track reactions, see which sites are overdue.
Abdomen · Thigh · Upper arm · Reaction logging
