Development of the Train Tickets mobile app for Tutu.ru

Tutu.ru is a travel service, which is number one in Russia (according to GfK Rus)*. The customer highly appreciated our approach to work and we won the tender Cooperation process consisted of the stage before the redesign and the final one. Firstly, we designed the interface, then we made the UI design of the app and developed an Android application. After the Tutu.ru redesign, we redesigned the application and adapted the new design for Android.

There are complicated business logic and numerous nuances behind the ticket selection process. It was important to take into account product features to make the purchase of train tickets easy and enjoyable. The code also should be easily maintained for a client.

We worked closely with the Tutu.ru product team to find out all the details and possible scenarios. The team projected, showed, and modified screens taking into account the customer’s product expertise. As a result, they presented a high-volume product in simple «packaging» for the customer and the user.

During the design phase all the functionality was divided into blocks corresponding to the buying process: route choice, search output, carriage, and seat selection, passenger data entry, payment process, and auxiliary screen. We have continuously worked on each block in order to simplify work on such a large-scale product.

An option with one type of carriage, an option with five types of the train carriage, and an option with «passing trains». Each state was organized and saved in the prototype. We analyzed most of the user scenarios during the projection stage of the basic screens and offered a well-thought-out interface concept.

It is hard to maintain an app when it consists of 120 interrelated screens. To add a new screen, you have to edit all the previous ones and write a lot of code. It is easy to get confused.

Our Android developer Konstantin Tshovrebov came up with a solution that allowed us to separate all the logic from the interface. Now you just need to turn to the logic instead of rewriting its parts to add a new screen. The ready-made solution is framed in the library. We wrote about it on Habr.
