Pop-up Challenge
For Pop-up Challenge, SOLIS developed a mobile application that turns the discovery of Alpine regions into a seasonal game. Participants choose a destination, activate challenges and collect points, while a management interface supports routes and competitions.

The initial challenge
Connect the discovery of Alpine destinations with challenges on the ground, while giving organisers tools to manage points of interest, validate routes and run competitions.
The solution delivered
Aurélien, Aymeric and several colleagues developed the mobile application and its management interface over one year. A QR code at the destination validates each route; results feed into the database, and a participant ranking supports the distribution of rewards.
Behind the scenes of the project

Challenges experienced on the ground
The application lets participants choose a destination and activate its challenges. A QR code at the destination connects the physical route with its validation in the application.
Results feed into the database and contribute to participant rankings. This gives organisers a basis for running competitions and assigning rewards.
The organisers’ tools behind the application
A management interface complements the mobile experience, allowing organisers to create challenges and manage points of interest. The project combines React Native, Next.js, Firebase and AWS.
Aurélien, Aymeric and several colleagues worked on the project for one year. Delivered in 2023, the application is available on the App Store and has also been featured in regional media.
