The client
TRVL.gr, in your pocket
TRVL.gr is a Greek online travel agency for hotels, apartments and villas across Greece. The website already sold stays; the app had to do the same on a phone, where most trips are now planned — and keep the guest after the booking, not only before it.
TRVL Air is the result: one app for iPhone and Android, built on the same platform as the website, so every hotel, price and booking is the same wherever the guest opens it.
01
Finding a place to stay
- By destination or on the map
- Search a place or a hotel by name, or move around the map; filter by price and amenities, set dates and guests, and see what is actually available at the price that will be charged.
- Hotel pages made for a phone
- Photographs and the property's own video in one gallery, rooms and cancellation terms spelled out, and a heart to save it for later.
02
Paying
- Card, Apple Pay or Klarna
- Checkout in a few taps, with the option to pay for the stay in three instalments with Klarna — the same way TRVL.gr offers it on the web.
- Signing in without a password
- Sign in with Apple, with Google, or with a six-digit code sent by email. Nothing to remember, nothing to reset.
03
After the booking
- Everything in one place
- Bookings kept in the app, a review once the stay is over, and a support chat with the TRVL team in Greek or English.
- A reason to come back
- Saved hotels are watched: when the price of one drops, the guest hears about it by notification and by email.
04
Built to keep moving
- One codebase, two stores
- Written once in React Native and released to the App Store and Google Play, so both platforms get every change on the same day.
- Fixes without the wait
- Most changes reach phones over the air, without waiting for another store review — a wrong date or a broken screen is fixed in hours, not days.
