BottleChallenge: water refill
Free water refill near you
Free · Designed for iPad. Not verified for macOS.
Every time you refill your bottle instead of buying a new plastic one, something small but real happens. Less plastic to carry, less money spent. And with BottleChallenge, you actually get rewarded for it.
Find free water near you
The map shows refill points around you: cafes, restaurants, museums, gyms, and other venues that offer free tap water to anyone who asks. Updated by the community, so it keeps growing wherever you go.
Earn real rewards
Every refill earns you EcoDrops. Collect enough and redeem them for cinema tickets, theater and museum entries, concert passes, and special offers from local venues. The more you refill, the more you unlock.
Track your refills
BottleChallenge counts your refills and shows how many half-litre bottles of water you've filled. Share it or just enjoy watching the number grow.
Scan and collect
At participating venues, tap the NFC tag to instantly log your refill and earn EcoDrops on the spot. No manual input needed.
Build the network
Know a cafe or gym that offers free water but isn't on the map yet? Add it, upload a photo, and make it easier for everyone else to find. The network grows with every contribution.
BottleChallenge is a free nonprofit app by BrainGreen Foundation. No ads, no subscriptions, just a community of people who believe that small habits, done consistently, actually change things.

New look for League: your team board, search and filters in the table, and ranking per person. Team prizes with a collection code. The app now tells you when a new version is out. Fixes: camera when improving a place, opening hours in the list of places, and better stability on iOS.
