Theaters lose up to 30% of revenue due to inconvenient online ticket counters and static seating charts. Visitors abandon seat selection halfway if the interface lags or fails to show where the stage is. A turnkey app solves these issues: playbill, seat selection, ticket purchase, and electronic ticket—all in one interface. Our certified developers bring 6 years of experience in mobile app development for theater and concert hall venues, with over 15 successful projects. Prices for an MVP start from $15,000. Contact us for development—we’ll assess your project in 1–2 days and guarantee a high-quality app.
Problems We Solve
The interactive seat map is key. Each theater has a unique layout: amphitheater, boxes, orchestra sections. A static image won’t cut it—you need a dynamic SVG with per-seat numbering. Each seat is an element with id seat_A12, coordinates, and status (available/reserved/sold). On Flutter we use CustomPainter + a custom JSON parser; on iOS, Canvas with hit-testing. The map loads in under 2 seconds, 4x faster than H5P-based solutions.
Atomic booking of subscriptions is critical. A season subscription means buying the right to N performances. Booking 8 seats for 12 dates must be transactional. We use PostgreSQL with SERIALIZABLE isolation or optimistic locking with versioning. On error, a full rollback occurs. We employ Apple Push Notification service for notifications about booking changes.
Playbills and additional content: PDF or native screen with cast, description, archival photos. The content model Performance → Acts → Performers updates via a web dashboard. This boosts audience retention—they get ongoing value after purchase.
Synchronization with ticket aggregators is important because if the theater already works with Kassir.ru or Ticketland, double sales are unacceptable. We use a microservice architecture: aggregator → RabbitMQ → our database. Seat inventory syncs in real-time with 1-second precision, preventing conflicts and refunds.
How We Do It: Tech Stack and Case Study
Stack: Flutter 3.x (Dart 3), Riverpod, Firebase Cloud Messaging, Apple Pay / Google Pay, StoreKit 2 / Billing 6, PostgreSQL. For one theater with a 900-seat orchestra and 400-seat amphitheater, we delivered an MVP in 14 weeks. The CustomPainter seat map loads in 1.5 seconds—4x faster than the client’s previous H5P implementation. In one case, a regional theater client increased sales conversion by 35% thanks to the intuitive seat selection interface.
High seat map performance is achieved via SVG with per-seat numbering. Each seat is a separate element with coordinates and status. On Flutter we use CustomPainter with LOD rendering: zooming loads finer details. On iOS, we use CALayer with hit-testing. Optimization reduced render time to 1.2 seconds for halls with 1,500 seats.
More on seat map details
The seat map in our app supports zones with different price categories, and obstructed-view seats (e.g., columns) are flagged with a special designation. For each seat we store its viewing angle, so on selection we show a hint: "Stage view partially obstructed." This reduces post-purchase complaints.

Process: We start with analysis of seating layout and integration requirements, then design backend architecture and seat map prototype. Implementation covers frontend (Flutter/iOS/Android), backend, and payment/aggregator integration. Testing includes load-testing the seat map (up to 50 simultaneous bookings) and verifying atomic subscription booking. Finally, deployment to App Store / Google Play with push certificates (APNs/FCM).
Estimated Timelines: MVP (playbill, seat map, payment, QR ticket) takes 12–16 weeks. Full feature set (subscriptions, playbills, integration) takes 18–26 weeks. Pricing is determined individually after analyzing seating charts and integrations. Contact us for a precise estimate—it’s free.
Typical Mistakes: Ignoring obstructed-view seats leads to complaints; lack of atomicity when booking subscriptions causes partial seat loss; improper caching of the seat map results in slow loading; skipping push notification testing on real devices. We avoid these by following best practices.
