Spurenfuchs
Spurenfuchs gets children – and adults – out into nature: photograph beetles, birds, flowers or mushrooms, Fini the fox identifies the species, and every species becomes its own trading card in the album. Free with short, child-friendly ads or with the Explorer Pass.

The challenge
Children spend a lot of time on screens and little outdoors. Field guides are too dry for them, and many nature apps are reference tools for adults – with accounts, ad networks and little joy. The brief was an app that sparks curiosity and gets kids outside without collecting data about them.
The solution
Spurenfuchs works without an account, email or name. One photo is enough: an AI identifies animals, plants and fungi and creates a trading card with rarity, place of discovery and a fact from Fini – the photo and location are not stored. Badges, daily missions, photo bingo, expeditions, quizzes, memory, seasonal events and an optional league keep curiosity alive; Fini can be dressed up in the wardrobe. For children there is a parental lock before purchases and only child-friendly ads without links. As you scroll, the website tells a story from the sky down to the forest floor and – like the app – adapts to the season and the time of day. Ad slots, rewards and the blog are managed in a dedicated operator area without touching the code.
The outcome
The website is live at spurenfuchs.at, with a blog and its own area for advertisers. The iPhone app is currently being tested via TestFlight and prepared for the App Store – with Explorer Pass, Taler packs and 100 badges in three tiers each.
