How It Works

Loop. Badge. Neighborhood.

Three steps — one experience. No points, no fitness pressure. Just curiosity, movement, and a smartphone.

1
Walking
Move
Walk a Ring

Start a Loop in your city — on foot, at your pace, through your neighborhood. GPS runs in the background via CursusX. You choose the route.

2
Territory
Claim
Close the Ring, Earn a Badge

When the circle closes, the enclosed area becomes your territory. The Badge appears automatically on your digital wallet card — signed, tamper-proof.

3
Partner Discount
Redeem
Unlock Neighborhood Rewards

Your Badge status opens doors at local partner businesses: discounts, extras, access to special Loops. Climate action as currency between movement and local shopping.

Wallet Card.

No account required — the wallet card lands automatically on your iPhone or Android.

🔐
Cryptographically signed
Every Badge is signed by CursusX — permanent, tamper-proof, with the date and location of your Loop.
📱
Directly in Apple Wallet / Google Wallet
One tap — the encirkl card appears on your home screen. No login, no data, no profile required.
🛍️
Automatic partner recognition
Partner point-of-sale systems recognize your Badge status via CursusX API in real time — without scanning anything.
🔒
GDPR by Design
No movement profiles, no personal GPS data. Only anonymized area data — structural, not retroactive.
The Badge System

No points. Symbols of achievement.

For Local Businesses & Institutions

No Ad Space.
Real People.

Three problems. One mechanism. encirkl doesn't start with the product — it starts with the problems it solves.

🧍
Problem 1 — The User
No reason to step outside.

Fitness apps demand athletic ambition. Stamp cards motivate no one. What's missing is an incentive that isn't moral or athletic — but playful and instantly rewarding.

encirkl turns walking into a game — with real benefits from the very first Loop.
🏪
Problem 2 — Retail
Foot traffic drops, and nobody knows why.

Online shopping grows, city centers empty out. Payback no longer differentiates. Retailers need regulars instead of one-time buyers — and a system that rewards at the door, not just at checkout.

encirkl brings motivated locals right to your door — scalable from 29 EUR / month.
🌳
Problem 3 — The City
Climate goals without tools for activation.

Berlin aims to be climate-neutral. But climate neutrality happens through thousands of small behavior changes — not government resolutions alone. What's missing are tools that provide concrete incentives and deliver anonymized data at the same time.

encirkl delivers incentives and data simultaneously — grant-eligible and GDPR-compliant.
One product. Three problems solved. Not three products for three audiences, but one mechanism that by design addresses all three at once.

Ready to
encircle Berlin?

Whether as a walker, neighborhood partner, or city initiative — encirkl connects movement, community, and local economy into one ecosystem.

encirkl is a loyalty program where you walk your way to rewards instead of collecting points. You walk a loop through your neighborhood — no matter how fast, no matter how athletic — and unlock real benefits at the cafe, bookshop, or museum next door. For the city, it's everyday climate action. For the retailer, it's a new kind of regular customer. For you, it's a reason to take a walk on Saturday morning before breakfast.
