Re:Fill
Re:Fill reminds you when it is time to take your medication or supplements, writes what you took onto a calendar, counts down what is left in the bottle, and tells you to restock before you run out. Dose history exports to PDF or Excel for appointments, and your data backs up to your own Google or Apple account.

- Dose remindersSet morning, lunch, evening, or any time you like. Mark a dose taken straight from the notification.
- Stock countdownEnter the quantity once. Every recorded dose subtracts from it, so you can see how many days each item has left.
- Refill alertsDecide how many days' supply should trigger the warning, and hear about it before the bottle is empty.
- Calendar and exportTaken, skipped, and missed doses organized by date. Export any date range to PDF or Excel.
Re:Fill is not a medical device. It does not diagnose, treat, or prescribe. Talk to a doctor or pharmacist before making any decision about your medication.
