Always know when your next dose is due
Weekly, daily, every 10 days or every 14 days: enter the schedule your prescriber gave you and Doser counts down to the next dose without guessing for you.

Weekly doses are easy to lose track of, and 10 or 14-day gaps are harder still. Doser shows the next one on the first screen.

Frequently asked questions
Which schedules are supported?
Weekly, daily, every 10 days or every 14 days.
Does Doser decide my schedule?
No. You set your own schedule, as your prescriber gave it to you, and Doser counts down from it.
Can I check a date without the app?
Yes. The free next dose date tool on this site works in your browser and stores nothing.
