Mobile App Development for Gas Station (Fuel Station)
A mobile app for a gas station is more than just a map with fuel prices. A competitive product in this niche is built around three things: pre-authorization (payment without leaving your car), a loyalty program with real cashback, and integration with pump controllers via the station operator's protocol.
Key Integrations and Technical Details
Pump Control Protocols. Most Russian and Ukrainian gas station networks work with PTK "Mercury", "Topaz", or similar via OPC-server or proprietary TCP/API. Mobile apps don't control pumps directly — a server middleware sits between the app and physical equipment. Our task: correctly implement start/stop fuel pump commands and real-time pump status polling (liters, amount) via WebSocket or Server-Sent Events.
Payments. Integration with payment processors: CloudPayments, YooKassa, LiqPay — depends on the country. Saved cards via tokenization (PCI DSS SAQ A — responsibility lies with the payment gateway). Apple Pay via PKPaymentAuthorizationController, Google Pay via Google Pay API. Critical: transaction timeout must align with fuel delivery start time — if payment hangs, the pump must not start.
Geolocation and Station Map. CoreLocation / FusedLocationProviderClient, marker clustering on zoom out, filtering by fuel type. Fuel prices sync via API with no more than 5-minute delay (prices change several times daily).
Loyalty Program. Points accrual per liter, QR or barcode for checkout identification — AVFoundation/ML Kit Barcode Scanning. Transaction history, special offer notifications via FCM/APNs.
Stack: React Native or Flutter (depends on client requirements), REST API + WebSocket for real-time pump status, Firebase Crashlytics for monitoring.
Timeline: MVP with basic fueling and map — 10–14 weeks. Full product with loyalty program and history — 5–7 months. Pricing is calculated individually after analyzing equipment integration requirements.
