Track your GLP-1 weight loss journey simply and visually.
DosePen is the most intuitive tracker for people taking medications like semaglutide, tirzepatide, or liraglutide for weight loss. Log doses, track your weight, and monitor side effects. All in one place, all on your phone, no account or internet needed.
INJECTION SITE BODY MAP
Tap the exact injection site on a visual body map. See where your last dose was, when each site was last used, and get automatic rotation suggestions to avoid lipodystrophy. 10 injection points with full history.
QUICK DOSE LOGGING
Log a dose in under 15 seconds. Select your medication, tap the dose, choose the site on the body map, and done. No long forms, no unnecessary fields. The app remembers your usual dose and suggests the next site.
PROGRESS CHARTS
Visualize your weight loss with clear, intuitive charts. See weekly trends, track your progress over time, and compare against your goal. Beautiful charts built with Swift Charts.
SIDE EFFECTS
Log nausea, fatigue, headache, dizziness, constipation, and other common GLP-1 symptoms with severity levels (mild, moderate, severe). See correlations between dose changes and side effect onset over time.
PROGRESS PHOTOS
Capture progress photos and compare your transformation side by side. Visual timeline gallery showing your journey alongside weight data.
SMART DASHBOARD
Your dashboard adapts to your day. Shows when it's dose day, whether you've logged, if you missed a dose, and how long until the next one. Clear information without confusion.
