Three reasons to keep it on your home screen

Small habit, real payoff. Here is what the app does for you every day.

Water in seconds

Open the app and the nearest free refill point is right there, in cafés, restaurants, hotels and public fountains. The map works offline too.

Rewards you actually want

Every refill earns EcoDrops. Trade them for cinema, theatre and museum tickets, concerts and hotel stays. Not points that expire, real experiences.
