Mobile App Development for Car Wash
A car wash is a high-frequency service with a short decision cycle. Customers don't plan a visit a week in advance — they drive by or take a detour if they see no queue. An app for a car wash must answer one question quickly: "When can I come in?"
Online Queue and Pre-Booking
The key feature is real-time wash status: "Available", "Small Queue (10 min)", "Busy (30+ min)". Status updates automatically from POS system data or manually by an operator.
Pre-booking for a specific time — for those who want to arrive without waiting. Time slots of 30–45 minutes (depending on wash program). Online booking offers a bonus (10% discount or additional service). This motivates users to book instead of arriving during peak hours.
"Your time in 15 minutes" notification via FCM reminds customers they have a booking.
Wash Program Cards
Visualize wash programs with photos, included services, price, and estimated duration. Not just a list — cards with Container + BoxDecoration + BoxShadow or custom InkWell with selection animation.
A comparison table of programs is a useful UI element for choosing:
| Program | Body | Wheels | Drying | Time |
|---|---|---|---|---|
| Express | + | — | — | 15 min |
| Standard | + | + | + | 30 min |
| Premium | + | + | + polish | 50 min |
Loyalty Card and Subscriptions
"10 Washes" subscription is popular. In the app: digital card showing progress, QR code for scanning at checkout. Generate QR via qr_flutter package; scanning at the POS terminal.
Cashback points with each wash motivate repeat visits. Point balance always visible on the home screen.
Geolocation and Multi-Location Networks
For networks: map showing all locations with current load status. Use flutter_map + custom markers with color indicators (green / yellow / red). When opening the app, automatically sort locations by distance via geolocator.
Tech Stack and Timeline
Flutter + Provider/Riverpod, Firebase Auth (SMS), FCM, REST API. Backend — Node.js or Laravel for MVP.
MVP (wash status, programs, booking, subscription): 6–8 weeks. With network map and owner analytics — add 3–4 weeks. Pricing is calculated individually.
