BottleChallenge

Every bottle you fill earns you 5 EcoDrops.

You get EcoDrops for filling your bottle at a water place that has a BottleChallenge sticker. All it takes is holding your phone to the sticker. You then swap EcoDrops for tickets, passes and discounts from reward sponsors.

EcoDrops cannot be bought, sold or passed on to anyone else. Everyone collects their own, by filling their bottle and helping the map of water places grow.

The app is free and has no ads.

Some stickers give extra EcoDrops on top. The full list is in the EcoDrops terms.

How you collect EcoDrops

  1. Find a sticker

    You get EcoDrops at water places with a BottleChallenge NFC sticker. At the other places on the map you fill your bottle just the same, only without EcoDrops.

  2. Fill your bottle

    Ask the staff for water or fill your bottle at the dispenser. Water at the places on the map is free.

  3. Hold your phone to the sticker

    The app records the refill and adds the EcoDrops to your Wallet straight away.

You can record at most 2 refills a day at one place. EcoDrops are given for at most 8 refills a day across all places together. A refill cannot be typed in by hand: only holding your phone to the sticker on site counts.

Other ways to get EcoDrops

Add a water place

Know a drinking fountain or a cafe that is missing from the map? Add it in the app with its location, a photo and the type of water. Once moderators approve the place, you get 5 EcoDrops.

Invite friends

You have your own invitation link in the app. You get 1 EcoDrop when the person you invited fills their bottle at a sticker for the first time. Signing up alone does not count.

Your first refill

Your first refill earns you a one-off 10 EcoDrops on top, so after your first bottle you already have 15.

BottleChallenge League

Team results, duels and tournaments neither give nor take EcoDrops. Everyone collects EcoDrops into their own Wallet, also while playing in a team.

A habit is easier to change when someone says thank you for it.

EcoDrops are how BottleChallenge and the reward sponsors say thank you for reaching for your own bottle instead of a single-use one. With every refill the reward gets closer and the habit becomes part of everyday life. Let’s take care of the environment together.

The Wallet

Your Wallet is in the app and on this website once you sign in. Everything that happens to your EcoDrops is recorded there.

  • Balance

    How many EcoDrops you have to spend right now.

  • History

    Every entry with its date: refills, places added, invitations, rewards collected and EcoDrops that expired.

  • Reward codes

    The codes of the rewards you collected, with their expiry date, ready to show at the partner.

  • Report a problem

    If a partner does not accept a valid code, or a reward is clearly different from its description, you report it with the button next to the reward.

Open the Wallet

How long EcoDrops are valid

6 months

EcoDrops you get at one time form a batch, valid for 6 months from the day you get them.

Oldest first

When you collect a reward, the EcoDrops closest to expiring are used first.

30 more days

If you fill your bottle when your oldest batch has less than 30 days left, it is extended once by 30 days.

Expired EcoDrops disappear from your balance, and the history in your Wallet shows how many expired and when.

What you can swap EcoDrops for

The Rewards section has tickets, passes, vouchers and discounts from reward sponsors: cinemas, theatres, museums, concert and workshop organisers, hotels and sports venues. Every reward shows its price in EcoDrops and how many refills that is.

A whole reward

A ticket, an entry or a pass for a fixed number of EcoDrops.

A fixed discount

A discount of a set percentage or amount for a fixed number of EcoDrops.

A discount you choose

You use a slider to choose how many EcoDrops to spend. The size of the discount depends on that number.

When you collect a reward, its code appears in your Wallet straight away. You show it at the partner or enter it on their website before the code expires (most often after 30 days).

See the rewards

Do you run a cinema, a theatre or a museum?

Rewards come from reward sponsors. The partner proposes the price in EcoDrops, and BottleChallenge approves the reward before it is published. The partner pays no fees or commission, and their reward brings in people who fill their own bottles.
