TOGETHER APP – Mobile App Development Case Study


Smartphone app to trace contacts and help to fight the coronavirus pandemic. Discover mobile app development case study.

Overview: The coronavirus outbreak has spread global panic, with people searching for sure-fire ways to protect themselves. While being in the lockdown, we decided to immediately respond to this need and provide a technology solution that increases our safety. After many brainstorming sessions, our team came up with Together – a mobile application designed to help protect our community from the virus. In only 3 weeks time we were able to produce a fully functional app with necessary features and an intuitive interface. We are proud to say that Together was a pioneering app of this type in Poland (and also Europe), and all success goes to an incredibly hard-working and committed team in Inspeerity.

The solution: The app was released free of charge, and could be used by anyone without a registration. It allowed the users to inform other members of the community about a confirmed infection. Thanks to the anonymously obtained location data, the user received a notification in case of contact with other users who have been confirmed with coronavirus infection within the previous two weeks. A very important feature of the Together application was the ability to quickly and easily check the history of your movement over the previous 14 days.
