Why I built it
I'm a parent and a software engineer. In September 2026 my toddler was diagnosed with SVT, a heart rhythm condition, and started on a medication given every 8 hours, with each dose needing to be within a 30 minute window. Fitting three doses around her naps, daycare, her bedtime and ours turned out to be a surprisingly annoying puzzle, so I built a small tool to work it out. DoseSchedule is that tool, cleaned up so anyone can use it.
How the planner works
Every few hours (q4h, q6h, q8h): doses are evenly spaced around the full 24 hours. You can slide the whole schedule earlier or later, and any dose that lands between your bedtime and wake-up time is marked as asleep. A dose right at bedtime counts as taken before you sleep.
A number of times a day (TID, QID): doses are spread evenly from your wake-up time to your bedtime, rounded to the nearest 15 minutes.
Reminders: Add to calendar creates a calendar file on your device with one daily repeating event per dose, which works with Apple Calendar, Google Calendar and Outlook.
What it isn't
DoseSchedule is a planning aid, not medical advice. It doesn't know anything about your medication, and it can't tell you whether a dose can be moved, skipped or taken late. Your doctor or pharmacist can.
Privacy
There's no account. Your schedule is saved only in your own browser so it's there when you come back, the calendar file is created on your device, and the medication name you type isn't saved or sent anywhere. The site uses Google Analytics to understand how people use it, such as which interval they pick. That doesn't include your dose times, sleep hours or medication name.
