Booking apps, guest apps and itinerary tools
Travel and Booking App Design and Development Services
Devoq Design designs and builds travel apps people keep on their phones: flight, hotel and package booking apps, hotel guest apps with mobile check-in and keys, itinerary managers, tour operator apps and loyalty programs. Mobile-first, accessible to WCAG 2.2 AA and connected to your PMS, CRM and GDS, with senior designers reviewing every screen.
Travel app development designed for the moments when travelers need it most
A travel app is judged in hard conditions. A passenger at a gate at 5am gets a change notification but the app needs a fresh login and a network call before it shows the new gate; we cache the itinerary and keep the session alive through the trip. A guest in a hotel lift with no signal taps a digital key that spins; we store keys and confirmations on the device and show plainly what is current. A traveler at a tour meeting point in an unfamiliar city cannot tell which of three saved bookings is today's; we design the home screen around the next event, not the account. A loyalty member books a room and only learns after paying that a member rate existed; we show status and member pricing at the point of booking. We design travel and booking apps around those moments, then build them with your engineers or ours. Whether you are an airline, a hotel group, an online travel agency or a tour operator, you get an app your guests open on the next trip too.
Our Services
Travel app design and development services by product type:
Flight and Hotel Booking Apps
Search, fare and room comparison, flexible dates, guest details and payment designed as one short path, with saved travelers and price alerts. Fare rules and change costs sit on the fare card so a traveler knows what they are buying before checkout.
Hotel Guest Apps
Mobile check-in and digital keys, room service and requests, messaging with the front desk and loyalty balances tied to your PMS. Keys and reservations are cached on the device so the lift and the corridor work without signal.
Itinerary and Trip Management Apps
Trips assembled from bookings and emails, live flight and transfer updates, documents stored offline and sharing with travel companions. The home screen leads with the next event, so the right booking is one tap away at the gate.
Tour Operator and Activity Apps
Departure schedules, meeting points, guide communication, waivers and in-app upgrades for day tours, cruises and multi-day adventures. Maps and meeting instructions work offline in places where roaming data is unreliable.
Loyalty and Membership Apps
Tier status, points earning and redemption, member rates and partner offers designed so loyalty is visible at the moment of booking. Earning and burning are explained in plain terms, with the next tier shown as a reachable step.
Features/Why Choose Us
- Works offline and under stress
Boarding passes, keys, confirmations and itineraries cached for use without a network, with large touch targets and clear states for travelers in a hurry. We design every critical screen for the worst connection on the trip and show plainly what is current and what is waiting to sync, because an app that spins at a gate is deleted before the return flight.
- Connected to your systems
App flows scoped against your PMS, CRM, GDS and payment provider so availability, rates, profiles and loyalty balances on screen are real and current. We document each integration before design, including how fresh each feed is, and draw fallback states for slow or failed calls. Screens designed ahead of the data are the usual cause of late releases, so we settle that first.
- Secure payments and privacy
Stored cards and wallets handled through tokenized, PCI DSS 4.0.1 aligned flows, with GDPR and UK GDPR consent, location permissions and data retention explained plainly. Permissions are requested in context: location when the airport map opens, notifications when a flight is saved. Each request states the reason, and declining never blocks the booking or the stay.
- AI assistance with human backup
Agentic trip planners and support assistants designed with visible sources and a one-tap route to a person, informed by how Booking Holdings reported agentic tools cut cost per booking by about 10% in 2025 (Morgan Stanley TMT, Mar 2026). The assistant confirms before it changes a booking and hands the full conversation to an agent, so a traveler never repeats the problem.

Our Approach to Travel App Development
Discovery and Research
01
Interviews with guests, agents and operations staff, review of app analytics and support tickets, and a map of the systems the app must talk to. App store reviews and uninstall timing show us which moment on the trip the current app fails.
Flow Mapping
02
Booking, pre-trip, in-trip and post-trip journeys mapped per traveler type, including offline moments and plan changes. Each step records the device state, signal, battery, one hand or two, and the data it depends on, so the flow is designed for the gate, not the desk.
Prototype and Test
03
Clickable interactive prototypes tested with real travelers on their own devices, including airport, hotel and low-signal scenarios. Participants complete a booking and a day-of-travel task under time pressure before any visual design is applied.
UI and Design System
04
Native iOS and Android patterns, accessible color and type, and a component library your engineers build directly from. Fare cards, itinerary rows, key and pass screens and loyalty badges are documented with every state, including offline, pending and expired.
Build and Release
05
Development with your team or ours, app store preparation, and analytics-led improvements after each release. We instrument the booking funnel and day-of-travel screens so the next release targets the step travelers actually struggle with.
Why Devoq Design?
The best travel apps disappear into the trip; that is the standard we design to.
Travel App Experience
Booking, guest, itinerary and loyalty apps designed with conversion, operations and compliance treated as a single brief. The Travelcall booking app shows how we handle search, pricing and payment on a small screen.
Design and Build Together
One team takes the product from research through UI into native or cross-platform code, so nothing is lost at handoff. Our mobile app development team works from the same design system as the designers.
Integration First
PMS, CRM, GDS and payment capabilities documented before design, so every screen shows data your systems can deliver. Fallback and error states are drawn for the days a connection is slow.
Accessible to WCAG 2.2 AA
Screen reader labels, dynamic type, contrast and focus order checked on every screen, not only the booking flow. Seat maps and calendars, the usual failures, get keyboard and VoiceOver paths from the first wireframe.
Ready for Many Markets
Currencies, time zones, languages, consent and wallet habits for US, UK, European, Australian and New Zealand travelers. One app serves every market with the right payment methods and date formats.
AI Speed, Senior Review
AI drafts screens, copy and research summaries about 5x faster; senior designers decide every screen that ships. The time saved goes into more rounds of testing with travelers on real devices.

Frequently Asked Questions
What does travel app development include?
Traveler research, journey mapping, wireframes and clickable prototypes, visual design, a design system, accessibility checks, native or cross-platform development, app store preparation and post-release optimization for booking, guest, itinerary, tour operator and loyalty apps. Every engagement also includes an integration map of your PMS, CRM, GDS and payment provider, offline and permission design for the day-of-travel screens, and a record of the payment and consent decisions for your compliance review.
Can you redesign our existing travel or hotel app?
Yes. We start with an app audit, analytics and store reviews to find where travelers abandon or uninstall, then redesign those flows first while preserving your PMS, booking and payment integrations. On most apps the first targets are login, the booking checkout and the day-of-travel home screen. Releases are staged so existing users are not disrupted, and each release is measured against the flow it replaced before the next one starts.
Do you build the app or only design it?
Both. Our designers and developers work as one team, so the app can be designed and built by Devoq Design, or designed by us and built by your engineers from our developer-ready files, tokens and documentation. If your team builds, we stay available during development to answer questions about states and edge cases, and we review the build against the design system before release so what ships matches what was tested.
How do you connect the app to our PMS, CRM or GDS?
We document what each system can expose: rates, availability, guest profiles, loyalty tiers, keys and messaging, and how often each refreshes. The app is designed to those capabilities and built against your existing APIs, so integration work is planned rather than discovered late. Where a feed is slow or unavailable, such as a partner tour inventory, the design shows an honest on-request state instead of a spinner.
Can the app include AI trip planning or support features?
Yes. 61% of travel executives are experimenting with or scaling agentic AI (Phocuswright via ITB, Mar 2026). We design assistants and agent flows with visible sources, live pricing and a human escalation path, so AI speeds the traveler without trapping them. The assistant confirms before it books or changes anything, shows which fares and policies it used, and passes the conversation to an agent with the context intact when it cannot help.
How much does travel app development cost?
Cost depends on platforms, the number of flows, integrations, offline requirements and whether we also build the app. A guest app for one hotel group with a single PMS is a smaller scope than a booking app with flights, hotels and packages across several markets. After a short discovery call we quote a fixed price for a defined first release or a monthly retainer for ongoing product work, where the roadmap keeps adding features each season.
How do you handle payments, location data and privacy?
Payments run through tokenized, PCI DSS 4.0.1 aligned flows with your provider, so the app never stores raw card data. Location, notification and data permissions are requested in context with plain explanations, and declining never blocks a booking. Consent and retention follow GDPR, UK GDPR and the Australian and New Zealand Privacy Acts where you operate. We document the decisions for your compliance review rather than offering legal advice.
Will the app work offline and in poor signal?
Yes. Boarding passes, digital keys, confirmations, itineraries and documents are designed to be cached on the device, with clear states showing what is current and what will sync when the connection returns. We test prototypes in airplane mode and on throttled connections, because the screens a traveler needs most are usually opened where signal is worst: aircraft doors, hotel lifts, basements and remote tour meeting points. Files and code are yours from the first week.
