Your local app agency with 10 years of experience – from concept to market.
Constance is the largest city on Lake Constance and unique due to its direct border with Switzerland (Kreuzlingen). The city combines vibrant tourism, university research, and cross-border trade. Companies need mobile solutions for guest management, multilingual services, booking systems, and international e-commerce applications with currency handling (EUR/CHF).
As an app agency, we understand the particularities of the Lake Constance region. From tourism apps for hotels and leisure providers to student services for the university to cross-border trading platforms – we develop mobile applications for the international requirements of the region.
Typical challenges: Multilingualism (DE/EN/FR/IT), seasonal traffic peaks in tourism, integration with Swiss systems, currency conversion, and cross-border payment processing.
Tourism & Hospitality: Hotel and restaurant apps: mobile check-in/check-out, digital guest folders, concierge services, and review management. Booking systems with availability calendars, payment integration, and interfaces to Booking.com, HRS, and regional platforms.
Lake Constance Experiences: Interactive guides for attractions, boat tours, and events. Multilingual audio guides, AR features for historical sites, and offline maps for hiking and cycling. Event apps for festivals and concerts by the lake.
Cross-Border Commerce: E-commerce apps for cross-border trade with currency selection (EUR/CHF), tax calculation for different countries, and integration with Swiss and German payment systems (Twint, PostFinance, Giropay).
University & Campus: Apps for students: lecture schedules, cafeteria menus, campus navigation, library access, and messaging. Integration with university systems and digital student IDs.
Water Sports & Leisure: Booking systems for sailing schools, surf courses, and boat rentals. Weather and wind forecasts, water levels, and safety information for water sports enthusiasts.
Flutter with Internationalization: Flutter's internationalization (i18n) enables easy multilingualism – essential for the international Lake Constance region. Support for localized date formats, currencies, and cultural particularities.
Payment Integration: Connection of various payment systems: Stripe, PayPal, Swiss Twint, PostFinance, and German Giropay. Currency conversion and tax calculation for cross-border transactions.
Scalable Backend Systems: Cloud infrastructures that handle peak loads in summer (Lake Constance high season). Auto-scaling for increased traffic and performant APIs for fast response times.
Offline Functionality: Important for tourism apps: offline access to maps, guides, and saved information – even without data connection on shore or on the lake.
