A GLP-1 tracker that stays out of your way.
Log your weekly shot in two taps, keep a simple injection site log, and see your weight with every dose change marked. No account. Nothing leaves your phone.
Log a shot in 2 taps
Today shows your next dose. Tap Log shot and the dose is prefilled from last time. Pens, vials, and pills all work, with doses in mg, mcg, or syringe units.
A simple injection site log
See where you injected and when. VialBook suggests the site you used least recently so you can rotate. It is a suggestion drawn from your own history, never a prescription.
Weight and dose steps on one chart
Weight belongs to a date, not to a dose. When your dose changes, the change is marked on the chart so the story reads at a glance, and it is easy to show your doctor.
Missed a shot? Amber, not guilt
A dose you did not log shows in amber with a Resolve button. Mark it taken or skipped. There are no streaks, no percentages, and no red guilt screens.
Private by design
No account, no server, no analytics. Hide names swaps the medicine name for a neutral label in the app, on reminders, and on the Lock Screen.
VialBook is a tracking tool, not medical advice. It never suggests a dose. Talk to your doctor about your treatment.
Is there a free GLP-1 tracker?
Yes. VialBook is free to start and covers one medicine and the last 30 days of history. Backup and export are always free.
Does VialBook tell me my GLP-1 dose?
No. It never suggests a dose. It shows the numbers you typed and what you logged. Your doctor decides your dose.
Do I need an account?
No. There is no account and nothing leaves your phone.
Can I track more than one medicine?
Yes, with Pro. You can add as many medicines as you take, each with its own schedule and color.
