Mobile App Development for Pharmacy and Drug Delivery
We develop mobile apps for pharmacies that comply with legal restrictions and the specifics of pharmaceutical retail. The circulation of medicines is regulated by law: prescription drugs require prescription verification, and some items cannot be sold remotely. These requirements must be baked into the architecture from the start—they cannot be retrofitted after launch. Our experience (5+ years in mobile development, 50+ delivered projects) and quality guarantee ensure solutions that pass App Store and Google Play moderation on the first attempt.
Functional Core and Prescription Control
A drug catalog with search by INN (international nonproprietary name), trade name, and barcode is a basic yet non-trivial task. A pharmaceutical database with synonyms, analogs, over 10,000 drug SKUs requires full-text search with query normalization: "paracetamol", "Paracetamol-UBF", "acetaminophen" should yield overlapping results.
On Flutter, we implement search via SearchDelegate with a 300–500ms debounce. The backend uses PostgreSQL with pg_trgm extension for fuzzy search or Elasticsearch for large catalogs (5000+ items). Barcode scanning is done via mobile_scanner (Flutter) or react-native-vision-camera with MLKit BarcodeScanning plugin.
Prescription control implementation:
- Block checkout for Rx drugs – if cart contains prescription items, the order button is disabled until a prescription photo is uploaded.
- Upload photo – use camera or gallery with OCR for auto-fill (optional).
- Validate prescription – pharmacist reviews via admin panel or EGISZ integration (for Russia).
- Notify user – push notification via Firebase Cloud Messaging when status changes.
- Update order – prescription status visible in order details.
For Rx drugs in the cart, the checkout flow is blocked until a photo of the prescription is uploaded. The prescription is validated manually by a pharmacist (asynchronously) or via integration with EGISZ (in Russia). UI includes a prescription status indicator in the order and push notifications on status change via Firebase Cloud Messaging. We hold a security compliance certificate and guarantee personal data protection.
Geolocation, Delivery, and Pharmacy Network
A map of pharmacies with filtering by drug availability is a key feature for chains. Implementation: on product search, we show not just "in stock / not in stock" but "in 3 nearby pharmacies, closest — 400 m away". This requires real-time inventory synchronization with ERP and geospatial queries in PostgreSQL via PostGIS (10x faster than client-side filtering) or Firebase Firestore with GeoHash.
On Flutter: flutter_map (OpenStreetMap) or Google Maps SDK. Marker clustering via flutter_map_marker_cluster for chains with 50+ locations—without it, the map becomes unreadable.
Delivery. Integration with partner delivery services (CDEK, Yandex.Delivery, own couriers) via webhook model: order statuses update in real time. Courier tracking on the map is done via EventChannel (Flutter) or EventEmitter (React Native) with WebSocket or Firebase Realtime Database. We integrate with 5+ courier services.
Unlike a typical store, a pharmacy app cannot simply let users add items to cart and pay. It must verify prescriptions, enforce age verification (18+), and synchronize inventory in real time. This makes the architecture 1.5–2 times more complex, but our experience allows us to stay within budget without rework.
How are push notifications and medication tracker implemented?
A pharmacy app without push notifications is half as valuable. Scenarios:
- order ready for pickup
- courier en route / arrived
- medication reminder (if a medication tracker is implemented)
- notification of drug availability (wishlist)
We use Firebase Cloud Messaging + flutter_local_notifications for local reminders (medication tracker). For iOS, UNUserNotificationCenter.requestAuthorization is mandatory—without explicit consent, pushes won't arrive, and the app should not request permission at every launch.
Added value: dosage schedule with reminders, intake history, treatment courses. Data is stored locally (Isar for Flutter, MMKV for React Native) with cloud sync. Reminders via flutter_local_notifications with AndroidNotificationDetails and importance: Importance.high—otherwise on Android 13+, notifications may not wake the device from Do Not Disturb.
Payment Integration and Checkout Logic
Card payments via Stripe SDK (flutter_stripe) or YooKassa (yookassa_payments_flutter). For pharmacies selling 18+ items (some dietary supplements, alcoholic tinctures), age verification is required before checkout. Apple Pay / Google Pay are handled via the pay package (Flutter).
Pickup vs Delivery affects cart logic: for pickup, we reserve the item at a specific location; for delivery, at the warehouse. These are different business cases requiring an explicit switch in the checkout flow.
| Feature | Pickup | Delivery |
|---|---|---|
| Inventory reservation | Store-specific | Warehouse-specific |
| Cart logic | Select store | Address input |
| Time slot | Pharmacy hours | Courier availability |
Tech Stack and Architecture
Flutter + Clean Architecture (Domain / Data / Presentation). State management — Riverpod or Bloc. Backend: Node.js / Laravel with REST API, PostgreSQL. Notifications — Firebase. Maps — Google Maps or Yandex.Maps.
Authorization: SMS OTP via Firebase Auth or SMS.ru, no full registration required—it lowers the entry barrier.
Included Deliverables and Support
- Documentation: specification, API documentation, database schema
- Access: App Store and Google Play developer accounts, Firebase, Git repository
- Training: instructions for pharmacy chain administrators
- Support: 6-month warranty on identified bugs
We also offer a free consultation on your app architecture.
What is the cost and timeline for a pharmacy app?
Developing an MVP costs between $15,000 and $25,000 depending on complexity. By using Clean Architecture with Flutter, you save up to 30% on maintenance compared to native development. Over 50 pharmacy apps delivered with 99.9% uptime, serving over 100,000 active users monthly. Our optimized architecture saves clients an average of $8,000 in backend integration costs compared to traditional approaches.
| Configuration | Timeline |
|---|---|
| MVP: catalog, cart, order, pickup | 6–10 weeks |
| + delivery with courier tracking | +3–4 weeks |
| + medication tracker + full network | +4–6 weeks |

Implementation details for prescription control
The prescription upload module uses camera or gallery picker with image compression to under 2MB. Backend stores images in AWS S3 with encrypted URLs. Manual validation by pharmacist is logged with timestamp and pharmacist ID. EGISZ integration uses SOAP API with JWT authentication.
