PureDose helps you take the right dose at the right time—and miss fewer doses. TODAY CHECK-IN See what’s due today and mark doses Taken or Skipped. If you miss the check-in window, you can still make up a dose during the makeup period. You can also confirm from a dose notification, or check in quickly with the Home Screen widget. FLEXIBLE SCHEDULING Start from common templates (once daily, twice daily, three times daily, and more), or schedule around wake-up, meals, bedtime, or a custom clock. Support weekdays, every other day, every N hours, and as-needed (PRN) dosing, plus long-term meds and short courses with an end date. Optional quiet hours help reduce interruptions. RELIABLE REMINDERS Get system notifications when it’s time. On supported OS versions, you can also use system alarms. Same-minute doses can be grouped, and optional follow-up nudges help if you haven’t checked in yet. Travel mode can pause dose alarms while you’re away; schedules resync when your time zone changes. You can also hide medication names on lock-screen alerts. INVENTORY & REFILLS Optionally track remaining quantity—deducted when you mark Taken. Get alerts when you’re running low or a refill date is near. ADHERENCE & EXPORT History includes an adherence heatmap and completion overview.
