Penline
Every dose, kept
Penline keeps the run on semaglutide or tirzepatide in one place on your phone: each shot and the site it went in, each dose step, each weigh-in, drawn as one line, with a one-page report for your doctor.
- Shot and pill log
- Site rotation
- Doctor report
Four questions, and your run is on one chart.
Answer four questions and Penline draws your run so far. From then on, one tap a week keeps it.
Your whole run on one chart
Your weight line drawn over your dose steps, from the first dose to today, with each shot marked along the bottom.
The next site, picked for you
A body map with the site that has rested longest already chosen. The dose is the current one and the time is now, so logging is one tap on Save.
Ten seconds a day
Side effects as chips you tap once or twice for stronger, protein and water on steppers, and a view of the days since your last dose.
More in the app
The pill, too
The daily pill is a first-class answer, logged in one tap, and compounded vials take units with your vial's strength.
A report for your doctor
One page with the dose steps, the weight change and the side effects, as a PDF, and the full log as a CSV.
Reminders that say where
Dose day with the dose and the next site, a widget counting down, and an evening check-in if you want one.
A log, not advice
Penline records what you take. It never suggests a dose or a schedule.
