(I) The challenge
More than an info app
Glücksgefühle did not want an app that only gives information. They wanted one that feels like the festival. So at its center is a list of challenges, like a selfie with ten people or a hidden sticker on the main stage. Each task shows its status, and at the top you see how many you still need for your next reward.

(II) The solution
A photo as proof
Once you have done a task, you take a photo or pick one from your gallery and send it in. The team checks it, and if everything fits, the task moves to your completed ones.
On top of that, you scan your wristband and collect points for rewards.

(III) The tech
Only staff can redeem
You pick up your reward at the bar. Only the staff press the button to redeem it, and the app asks first whether it really is the bartender holding the phone. If you press it yourself, the reward is gone. We built the app with React, Firebase and Node.js, designed for around 200,000 visitors.

(IV) The impact
A festival that lets you play along
The photos from the challenges land in the Happy Feed, where everyone can like them. Complete enough tasks and you unlock a reward and reveal it in the app.
That turns visitors into players, all across the grounds.
