Questions about tracking
Which medications can I track?
Any injection you add. Pick one from the quick-start list or type a name, choose its unit, and enter its schedule as your prescriber set it. Each medication gets its own supply and shot reminder.
Is Tirzing free?
Yes. The free plan has no time limit and needs no card, and it covers the day-to-day logging: shots, supply, weight and how you feel. Some extra insights are on paid plans.
Does it work with pens and vials?
Both. A single-dose pen is marked used by the shot that uses it, a multi-dose pen counts down its doses, and a vial counts down by what you log, using the details printed on its label.
Can I track two medications at once?
Yes. Each one you add has its own schedule, supply and reminder. Your plan shows how many you can track at a time.
Does Tirzing tell me what to take or how much?
No. Tirzing records what your prescriber has set and what you logged. It never suggests a medication, a dose or a change. For anything about your treatment, follow your prescriber and the official prescribing information.
Is Tirzing made by Novo Nordisk or Eli Lilly?
No. Tirzing is an independent tracking app. It is not affiliated with or endorsed by either company, and it does not sell, prescribe or recommend any medication.
