Mobile product

Loter

The mobile app extends the Loter platform by providing users with a convenient way to track flight deals on the go. Users can define detailed travel preferences, including destinations, departure locations and budget ranges, directly within the app. These preferences are synchronized with backend processing systems that continuously scan for matching offers. When relevant deals appear, users receive push notifications in real time. The app also allows full management of saved preferences, including activation, deactivation and removal. This creates a seamless connection between user input, backend logic and real-time delivery.

Problem

The mobile app needed to deliver flight deals in real time based on user preferences, without requiring users to actively check the platform. This required synchronizing user-defined preferences from the app with backend data processing, while also giving users full control over their alerts (activation, deactivation and deletion). Ensuring reliable delivery and consistency between app state and backend logic was a key challenge.

Solution

We implemented a mobile-first notification flow where users define and manage their flight preferences directly in the app. These preferences are stored and processed on the backend, which continuously scans for matching deals. When a relevant offer appears, the system triggers push notifications to the user’s device. The app also provides full control over active alerts, allowing users to enable, disable or remove them at any time. This creates a seamless loop between user input, backend processing and real-time delivery.
