The client was already offering iOS and Android mobile applications to travelers who were planning their family holidays, business trips or getaways with friends. The apps offered a personalized experience that guided users through the booking process and secure and transparent payment options.

But there’s always room for improvement, so the client decided to enhance the existing applications to allow users to get through the flight booking processes within one minute. The larger goal was to build a scalable, maintainable and reusable travel solution.



Lemapp was chosen through a multi-tier tender process. The client paid careful attention to the previous experience and successful mobile projects we delivered for the Travel industry. The ability to start working just a few days after signing the contract was also critical.

For each new team member, the client organized:

  • personal meetings with a team of developers and managers to share experience and introduce the development process
  • technical interviews that involved solving algorithmic tasks
  • interviews with the product owners
  • 2-3 day-long coding tasks.

On average, it took 1-2 weeks to fully interview one candidate.

Lemapp’s team did everything, from setting up the applications’ fundamental structure to publishing thoroughly tested and integrated apps to marketplaces. Our tasks also involved:

  • splitting the functionality into logical blocks
  • supporting existing features
  • building new features
  • migrating to new APIs
  • redesigning the apps
  • improving performance
  • collaborating with the product team and different development sub-teams
  • support during peak loads.


Together with the client’s team, Lemapp developed new mobile application and enhanced tools for planning and booking trips. Thanks to the work we’ve done, the iOS and Android app users could:

Browse and filter over 1.5 million hotels and thousands of flights at the best prices

Access a personal account management system and track bookings

Address 24/7 customer support

Enjoy instant and secure payment methods: full payment, partial payment, the “Pay Later” function and via the bonus program

Easily book flight tickets and avoid paying high prices

Access exclusive deals thanks to various loyalty programs


As a result of integration the following numbers were gained

- 12% Costs of sales

-17% Number of ‘poor’ deals

+9% Increase in revenue

It was a pleasure to work with the development team provided for our project by Lemapp. All of the team members appeared to be qualified, highly responsible, dedicated specialists who know how to do their job good. Also, there was no problem with communication: we found the common ground quickly. In one word, we really liked Lemapp’s development services.
