Mobile App Development for Gas Stations (Fueling)
A mobile app for a gas station isn't just a price map. Three core features define a competitive product: pre-pump payment (pay without leaving your car), a loyalty program with real cashback, and integration with fuel pumps. One chain of 50 stations reduced service time by 30% after implementing pre-pump payment, and the average check increased by 15%. Customers save up to $2–3 per fill-up, and the network's additional revenue reaches $1.4k–1.9k per month from loyalty.
How to Integrate with Fuel Pumps?
Protocols for pump control. Most gas station networks work with PTK Mercury, Topaz via OPC server or proprietary TCP/API. The app does not control the pump directly — a server-side middleware sits between the app and the equipment. Our task: correctly implement start/stop fueling commands, real-time pump status polling (liters, amount) via WebSocket or SSE.
Why Is Contactless Payment Critical for Gas Stations?
Payments. Integration with payment gateways: CloudPayments, YooKassa, LiqPay. Saved cards via tokenization (PCI DSS SAQ A). Apple Pay via PKPaymentAuthorizationController, Google Pay via Google Pay API. Critical: the transaction timeout must be aligned with the start of fuel delivery — if payment hangs, the pump won't start. According to one project, proper synchronization reduced failed payments from 8% to 1.5%.
Geolocation and Station Map
CoreLocation / FusedLocationProviderClient, marker clustering when zoomed out, fuel type filter. Prices sync via API with a delay of no more than 5 minutes (prices change several times a day).
Loyalty Program
Accrue points per liter, QR code for identification at the cash desk — AVFoundation / ML Kit Barcode Scanning. Transaction history, notifications about promotions via FCM/APNs. Typical scheme: 1 point per liter, 100 points = $1–1 discount.
Technical Stack and Platform Comparison
| Component | iOS | Android | Cross-platform |
|---|---|---|---|
| Language/Framework | Swift 5.9+ | Kotlin + Jetpack Compose | Flutter 3.x / React Native |
| Payments | StoreKit 2 (in-app), Apple Pay | Billing 6, Google Pay | Plugins (flutter_stripe, react-native-google-pay) |
| Geolocation | CoreLocation | FusedLocationProviderClient | geolocator / react-native-geolocation |
| Push | APNs | FCM | Firebase Cloud Messaging |
Native apps work 1.5–2 times faster than cross-platform ones, but cross-platform reduces the budget by 35–40%. Platform choice affects timelines: cross-platform (Flutter/React Native) cuts development time in half compared to separate native projects, but may require additional work for specific gas station equipment integration.
Comparison of Pump Integration Methods
| Method | Complexity | Implementation time | Reliability |
|---|---|---|---|
| OPC server (Mercury, Topaz) | medium | 2–4 weeks | high |
| Proprietary TCP/API | low–medium | 1–3 weeks | medium |
| Custom protocol modification | high | 4–6 weeks | high after testing |
What Is Included in the Work
- Server middleware for pump communication (documentation, configuration)
- Payment gateway setup and card tokenization
- Integration with Federal Tax Service for receipts (if required)
- Publishing to App Store and Google Play (code signing setup, provisioning profile)
- Training gas station staff on using the app
- Technical support for 3 months after launch
Development Process
- Analytics: gather requirements for gas station equipment integration, choose stack.
- Design: architecture (Clean Architecture for iOS / MVVM for Android), UX/UI design.
- Implementation: iterative development with CI/CD (GitHub Actions, TestFlight, Firebase App Distribution).
- Testing: unit tests, UI tests (XCUITest/Espresso), load testing of payments.
- Deployment: publish to App Store and Google Play, configure Code Signing and Provisioning Profile.
Timelines and Cost
MVP (basic map + pre-pump payment) — from 10 to 14 weeks. Full product with loyalty program — from 5 to 7 months. Cost is determined individually after analyzing integration requirements for gas station equipment. Get a consultation — we will assess the complexity of your project. Contact us to discuss.
Common Mistakes in Gas Station Apps
- Lack of synchronization between payment timeout and pump start (fraud risk)
- Too infrequent price updates (customers see outdated data)
- Ignoring App Store Review Guidelines (section 4.2 — minimal functionality)
