Turnkey Hotel Booking Mobile App Development
Entering the hotel booking market with your own app is no easy task. Competitors like Booking.com have already captured the audience, but niches remain: regional hotels, corporate travel, properties under a specific category. We specialize in just such projects, and over 10+ years we have developed more than 20 apps for the hospitality industry. Our engineers hold Apple and Google certifications, and the solutions we use are tested under loads of thousands of bookings per day. Contact us for a free consultation.
Integration with PMS — Core of the Mobile App
The central technical challenge is obtaining real-time prices and room availability. There are three paths, and the choice depends on your business model.
Channel Manager API. If hotels are already connected to a channel manager (TravelLine, Bnovo, Reznext), this is a single point of entry. TravelLine provides a REST API for availability search and booking (TravelLine API Reference). One contract opens access to thousands of properties. We use this path most often — it gives maximum coverage at minimal integration cost.
Direct PMS Integration. Opera PMS, Fidelio, 1C:Hotel — each has its own API or SOAP. This is for working with a specific hotel network where full data control is required.
OTA Aggregators. Ostrovok B2B, Brroniru, HotelBeds — ready-made sources with a commission model. For a start, this is fastest, but commission lowers margins.
| Integration Type | Connection Speed | Data Control | Commission | Hotel Coverage |
|---|---|---|---|---|
| Channel Manager | 1–2 weeks | High | None | Thousands |
| PMS Direct | From 4 weeks | Full | None | Limited to network |
| OTA Aggregator | 1 week | Low | Yes | Millions |
// Availability request via channel manager API struct AvailabilityRequest: Encodable { let hotelId: String let checkIn: String // "2025-06-15" let checkOut: String // "2025-06-18" let adults: Int let children: Int let currency: String } struct RoomType: Decodable { let id: String let name: String let description: String let capacity: Int let pricePerNight: Decimal let cancellationPolicy: CancellationPolicy let images: [String] let availableRooms: Int } Why Map Clustering Matters
Searching for nearby hotels is a must-have feature. We use MapKit (iOS) with MKAnnotationView and clustering, or Google Maps SDK. When there are more than 100 objects, without clustering the map turns into a mess — clustering reduces the load by 70%. We use GMSMarkerClusterer (Google) or ClusterKit (MapKit). We replace markers with price badges — a custom MKAnnotationView with a UILabel. Tapping a cluster zooms in, and tapping an individual marker opens a bottom sheet with hotel details.
Geosearch: by center coordinates + radius. Backend uses PostGIS with ST_DWithin(location, ST_Point(lon, lat)::geography, radius_meters) — the query executes in <10 ms with a spatial index.
Date Picker and Dynamic Pricing
Date selection is one of the most challenging UI elements. Standard DatePicker doesn't work: you need a custom range picker that blocks unavailable dates and shows the minimum price under each date.
On iOS we implement it via UICollectionView with a custom layout — cells with range highlighting. On Android, we use MaterialDatePicker from Material Design 3 with DayViewDecorator.
More about dynamic pricing
Prices change according to demand. To avoid overloading the server, we cache them for 30 minutes. At final booking, we make a repeat request `GET /rooms/{id}/price-check?checkin=&checkout=`. If the price has changed, we warn the user and show the new one before payment.How Payment Works
The scheme depends on hotel policy. The most common options:
- Full prepayment — payment at the time of booking.
- Pay at check-in — reservation without payment, the hotel holds the room.
- Partial prepayment — hold via
payment.capture_mode = manualin YooKassa or Stripe.
Hold (preauthorization): via YooKassa — POST /payments with capture: false. After check-in — POST /payments/{id}/capture. On cancellation — POST /payments/{id}/cancel. Apple Pay and Google Pay are mandatory for conversion — Apple Pay boosts conversion by 20%. We integrate PKPaymentRequest on iOS and PaymentsClient on Android.
Booking Management and Reviews
The "My Bookings" screen shows active, past, and canceled bookings. Details include a voucher, an address with a deep link to navigation, and contacts. Cancellation includes a penalty calculation based on the cancellation policy — logic on the backend. Push notifications: confirmation, reminder 3 days before, and a request for a review 24 hours after checkout.
Review system with ratings by categories: location, cleanliness, staff, value for money. Verification — only those who have completed their trip. Moderation: automatic (ML classifier) or manual.

How We Do It: A Real Case
On a recent project for a regional hotel chain with 50 properties, we integrated their existing Bnovo channel manager using REST API. The main challenge was handling dynamic pricing updates in real time. By implementing a Redis cache layer with a 30-second invalidation and parallel requests for room details, we reduced the average API response time from 4.5 seconds to 1.2 seconds — a 3.75x improvement. The app also uses PostGIS for geosearch, enabling under-100ms queries even with thousands of hotels. The client reported a 25% increase in direct bookings within the first three months after launch. The total project cost was $95,000, delivering a 40% ROI in the first year.
