RosFound is a mobile application created for a 3-week specialization course at DTU as a part of the Master’s studies. It was done in collaboration with the organization “Roskilde Festival - Powered by DTU Students”.

The objective behind “Roskilde Festival - Powered by DTU Students” and its specialization course, is that students, in collaboration with a supervisor at DTU, create a project that relates to one of the many technical challenges found at the festival, and use the festival week to both carry out the research and present the project to the festival guests and other interested parties.

RosFound was created by 3 Computer Sciences students and aims to provide a more streamlined process for the typical early Lost & Found booth, such that finders and owners can directly coordinate the handover of the belongings. It acts similarly to the Facebook marketplace, DBA, and other related apps, although meant for lost and found items. It is the intention that a user would either use the app if they have found an item and would like it to be listed and claimed by the rightful owner, or if a person has lost an item and would like to search if it has been added in the app or subscribe to any future listings. It is a crowdsource depended application, meaning that it relies on festival guests contributing data to the app by creating listings for others to find.

It had capabilities such as:

• Creating of a listing for a found item, marking it as “with owner” or left behind at a location with map capabilities
• Search engine, taggings, etc for finding listings
• Notifications capabilities for chat messages and new subscribed listings
• Deep linking
• Subscribe to specific keywords in a listing
• User

It was deployed and released on the Google Play Store and surveys were done as a part of testing the application with the user base under the duration of the festival.

The technologies that were involved:

• React Native
• Firebase
• UI-Kitten
• NX.dev
• Redux toolkit
