DoseCalendar

Read full description

DoseCalendar turns your medications into a clear daily schedule — so you always know what's due, taken, or missed at a glance. WHAT IT DOES • Add your medications: enter each medicine, the times you take it, and whether it's every day or every other day. • A schedule built for today: every dose lined up by time, with one-tap Take or Skip. • Reminders that fire on time: get a notification at each dose time you set. • Adherence at a glance: a 7-day adherence percentage and a running streak of days you took every dose. • Interaction flags: DoseCalendar checks your list against a small reference set of well-known drug-pair combinations and flags the ones worth discussing with your pharmacist or doctor. PRIVATE BY DESIGN Your medication list lives on your device. No account to create, nothing to hand over. HONEST BY DESIGN Core tracking is free — schedule, reminders, adherence, and interaction flags for up to 3 medications. DoseCalendar Plus is an optional auto-renewing subscription that unlocks unlimited medications. Clearly priced, cancel anytime. The interaction flags are a limited reference list of common drug-pair combinations — not a complete, clinical, or licensed drug-interaction database. Always confirm with your pharmacist or doctor. Subscription: auto-renews unless canceled ≥24h before the period ends; payment charged to your Apple ID at confirmation; manage/cancel in App Store settings.
