iSite.lk - Tourism Booking App

iSite.lk tourism booking mobile app for Sri Lanka built by W3S Solutions with tour catalogue and secure card payments

Tourism Booking & Payment App

Book a Sri Lankan tour and pay by card - all from your phone

iSite.lk is a tourism booking platform for travellers exploring Sri Lanka. W3S Solutions designed and built the iSite native mobile app - a fast, on-the-go companion that lets visitors browse day tours, food tours, hotels and activities, check real-time availability for a chosen date, complete a full booking and pay securely by card without ever leaving the app.

Built as a cross-platform app for Android and iOS on the Ionic and Angular framework with a REST API back end, Firebase push notifications and offline support, iSite turns a traditional, agent-led tour-booking process into a self-service experience a traveller can finish in minutes from a beach, a hotel lobby or a tuk-tuk.

The Challenge: tour booking that didn't fit the modern traveller

Sri Lanka's tourism is mobile-first - visitors plan and decide on the move. But the conventional way of booking tours and experiences kept getting in their way, and it cost operators bookings they should have won:

  • pain point Booking meant emails, phone calls or walking into a travel desk
  • pain point Travellers couldn't see what was actually available on their date
  • pain point Paying often meant carrying cash or sharing card details over email
  • pain point Slow back-and-forth confirmations lost impulse and last-minute bookings
  • pain point Tours, hotels and activities were scattered across different channels
  • pain point No direct line to re-engage past visitors with new offers

iSite didn't need "a brochure app." It needed to be a complete pocket booking office - discover, reserve and pay in one flow. That's what we built.

How booking works

Four simple steps take a traveller from inspiration to a confirmed, paid-for tour - without a single phone call or email.

1

Discover Tours

Browse a live catalogue of day tours, food tours, hotels and activities across Sri Lanka.

2

Check Availability & Price

Pick your dates and party size and see real-time availability with the live price calculated instantly.

3

Pay Securely In-App

Pay with Visa or Mastercard right inside the app, with live card-type detection and validation.

4

Get Instant Confirmation

Your booking is confirmed on the spot and a push notification lands straight on your phone.

The Solution: discover, book and pay in one tap-through flow

iSite gives travellers a guided path from inspiration to confirmation. They browse a live catalogue of tours and experiences, pick a date and the number of adults and children, and the app checks availability and prices the trip in real time.

From there it's a smooth, step-by-step flow - review the package, enter billing details, and confirm - with everything pulled from a central system so prices, availability and confirmations are always accurate and instant.

Built for travellers on the move

Push Notifications

Firebase Cloud Messaging keeps a direct line to travellers - booking updates, reminders and new tour offers delivered straight to their phone.

icon
Works Offline & On the Go

Smart image caching, offline detection and one-tap call-to-book keep the app usable on patchy connections while travelling around the island.

icon
One App, Android & iOS

A single Ionic and Angular codebase delivers a fast, consistent native experience to every traveller, on both Android and iOS.

Pay by card, confirmed before you finish your coffee

The payment step is where most tourism apps fall down - iSite makes it the easy part. Travellers enter their Visa or Mastercard, the app validates the card type live, processes the payment through a secure gateway and returns an instant transaction confirmation, all inside the same booking flow.

Built on Ionic and Angular as a single codebase for Android and iOS, talking to a dedicated REST API, the app delivers a native experience that's fast, secure and consistent on every device.
