About this app

BottleZero helps you cut down on single-use plastic bottles by making every refill count.

Every time you refill a reusable bottle instead of buying a plastic one, log it with one tap. BottleZero turns that choice into your real impact — how much plastic you kept out of landfills, how much CO2 you prevented, and how much money you saved.

FEATURES
- One-tap logging with daily goals and streaks
- Real impact stats: plastic avoided, CO2 prevented, money saved
- A live map of nearby water refill fountains using OpenStreetMap
- Badges, levels, and unlockable perks as you save more
- Friend challenges with join codes and leaderboards
- A community counter showing what everyone using the app has saved together
- A new plastic-reduction fact every day
- Share your impact as a picture card
- Works offline, syncs across devices when signed in

BottleZero was built as a solo student project for the Congressional App Challenge. It has no ads and no third-party trackers — see the in-app Privacy Policy for exactly what is and is not collected.

What’s new

BottleZero's first public release. Track the plastic bottles you save, find nearby refill spots, build streaks, and take on challenges with friends.
