Travel tracking and day counting iOS app for expats and frequent international travelers


We were asked to create a travel tracking app with a unique geolocation solution that would be energy-optimized and able to locate users even in the offline mode. Moreover, the app had to take up as little device memory as possible and at the same time, integrate specific day counting algorithms.

What were we responsible for?

  • developing a native iOS app
  • developing a native Android app from scratch (work in progress)
  • UI/UX adjustments
  • manual tests.

Our users needed to have the ability to track their travels constantly, even when there is no Internet connection. So, we had to provide a stable tracking system that remains on even in the offline mode.

As a result, battery optimization became a key factor that we had to take care of. We also had to rewrite and improve the geolocation system that doesn’t need mobile data to work. It was created before we joined the project. With such a technology, the app can be used anywhere in the world where there is a cell phone signal.

Building and managing a complex database was also a challenge we were faced with.

Last but not least, we had to develop features that make it possible to export and import data from the app to different usable formats.
