A geolocation app for discounts and bonuses

  • Android
  • iOS
  • Service

The app for discounts and bonuses informs about discounts in the nearby locations and shows the path to the destination point. A user creates the path in two modes: by car or on foot. It is possible to include several locations to the list and all the locations will be shown along the path. Most locations have links to feedback on Yelp.

The app was created for users from the USA. It helps to save money and get discounts and coupons in hotels, restaurants, gas stations and so on.

Project in figures

  • 31 day of development of basic functionality
  • 2 developers, 1 QA, 1 project manage
  • 12 participants in usability testing

What we did:

  • Developed a location-based app;
  • The map always takes cue from the way for the convenience of users;
  • The speed of travelling by car and on foot differs that is why we applied Kalman filter for smoothing the movement irregularities.
