PenTrack: GLP-1 Tracker

Try it free for 7 days. Logging injections, reminders and supply tracking stay free forever after that.

Everything about your weight-loss shot in one place: injections, dose, weight and side effects.

No sign-up. No account. Your health data never leaves your iPhone.

STAY ON TOP OF IT • Next injection with a countdown and a reminder • Dose history across every titration step • Rotate injection sites, with a nudge when you repeat one • Log side effects per injection • Pen supply: how many doses are left and when to reorder

YOUR PROGRESS • Weight chart with a 7-day average instead of daily noise • Plan line: are you ahead of or behind your target? • Body measurements — when the scale stalls, the tape often still moves • BMI, milestones and average loss per week • Apple Health sync

FOR YOUR APPOINTMENT • Save the date, get reminded the day before • Report as PDF or CSV: adherence, dose history, side effects

SUPPORTED TREATMENTS Weekly and daily medications with active ingredients such as tirzepatide, semaglutide, liraglutide and dulaglutide. Dose steps, interval and titration window adjust themselves to match.

PENTRACK PRO Charts, detailed analytics, effect-per-dose comparison, plateau detection, PDF and CSV export, and custom reminders. Free for 7 days, then by subscription. Logging injections, the injection reminder and supply tracking stay free forever.

IMPORTANT PenTrack is not a medical device and does not replace medical advice. Always discuss dose changes with your doctor.
