Doseline

A private logbook for your GLP-1 journey: shots, sites, weight, side effects and reminders.

Doseline helps people on GLP-1 medication (such as semaglutide or tirzepatide pens) keep an honest, simple record: when you took your shot and where, how your weight is moving, which side effects showed up, and when the next dose is due. It is a logbook you control, stored only on your phone. It does not give medical advice; your prescriber does.

Log

  • One-tap shot log with dose, time and an injection-site picker on a body diagram.
  • Site rotation suggests the spot you used least recently.
  • Weight, side effects and water quick-logs on the Today screen, with a streak for on-time shots.

See progress

  • Weight chart with goal line, 7-day average, total and weekly change, % to goal and BMI.
  • Side-effect frequency and a dose timeline that shows each step-up.
  • Pen supply counter so you know when to refill.

Reminders and export

  • Shot reminder with lead time, weigh-in day, missed-shot nudge and refill reminder.
  • Export CSV or JSON, import a JSON backup, and build a PDF report to bring to your appointment.

Private by design

No account, no ads, no analytics, no upload. Your data never leaves your phone.
