FitBurn — a Web3 "train and earn" service

FitBurn is a Web3 service at the intersection of fitness and NFTs: the user works out, earns tokens (CAL) for it, and buys and levels up NFT T-shirt characters.

The task was to design the entire complex system — a wallet, a shop, the NFT interaction mechanics — and present it to the client as a working prototype. Two platforms: a desktop dashboard and a mobile app.

Sole designer of the dashboard and the app, working directly with the studio's art director. I briefed 3D artists on NFT T-shirt model variants; I defined the T-shirt mechanics themselves — rarity, states, wear, and distinguishing criteria.

I built a fully clickable prototype in Figma so the client could see the product in action — down to how pop-up windows behave on desktop and mobile.

I designed the whole system — from the wallet and token exchange to the NFT game mechanics and the phygital shop — and put it together as a fully clickable prototype. The client accepted the work and handed the designs off to development; from there we kept collaborating on the service's print and digital materials, and the project itself lived on for a few more years — whether it ever reached a public release, and in what form, I no longer know.

For me, this was above all an experience in designing a complex system — with stateful objects and shared logic across two platforms. At launch, the first metric I'd look at would be the share of new users who made it to a connected wallet: for a non-crypto audience, that's the tightest bottleneck.

Today I'd start differently — first I'd study services with a similar mechanic. With hindsight, it's clear that "leveling up an NFT T-shirt through workouts" isn't a unique find but base game logic: an object with buffs and debuffs, a reward for engagement. I'd borrow proven solutions from similar products rather than invent everything from scratch. That said, I'm still happy with the visual design: clean minimalism and the signature orange with a glow effect.
