Do I need a backend for a medication reminder app?

Not for a single user — local storage plus locally scheduled notifications works entirely offline, which is also better for privacy. You need a backend only when you add caregiver sharing or multi-device sync.

Are there legal considerations?

Yes. Keep the app to reminders and logging, avoid dosage advice or interaction warnings, and both stores expect a clear disclaimer that it is not a medical device. Handling health data also raises your privacy-policy obligations — write a real one before you submit.

How to Build a Medication Reminder App with AI (2026)

What a medication reminder app needs

Medications with dose, form, and schedule
Per-dose reminder notifications
Mark taken, skipped, or taken late
Adherence history and streaks
Refill countdown from remaining pill count

The screens

Screen	What it does
Today	Doses due today, grouped by time, with one-tap taken
Add Medication	Name, dose, form, schedule, reminder times, pill count
Medication Detail	Schedule, adherence history, refill countdown
History	Calendar of taken/skipped doses with an adherence percentage
Settings	Notification permissions, caregiver sharing, time zone

The data model

Medication: name, dose, form, schedule, remainingCount, refillThreshold
DoseTime: medicationId, timeOfDay, daysOfWeek
DoseLog: medicationId, scheduledAt, status, takenAt

The build prompt (copy this)

Paste this into ShipNative and it becomes a working React Native app with these screens, navigable in a live preview, in about two minutes:

“A medication reminder app. Users add medications with a dose, form, and schedule (daily, specific weekdays, or every N hours) and get a notification per dose. Each dose can be marked taken, skipped, or taken late. Screens: Today (doses due, grouped by time, one-tap taken), Add Medication, Medication Detail (schedule + adherence history + refill countdown from remaining pill count), History (calendar with adherence percentage), Settings. Works offline; notifications are scheduled locally.”

Then iterate with small, screen-specific prompts (“make the primary button bigger”, “add an empty state”), preview on your own phone, and export the full Expo project whenever you want. The full method: how to build an app with AI.

How it makes money

Subscription ($3–5/mo) gated on caregiver sharing, adherence export for a doctor visit, and unlimited medications — free tier covers two. Do not gate the reminders themselves; a reminder app that silently stops reminding is how you earn one-star reviews.
