The Ocean Bottle app makes it super easy to help the planet while keeping yourself hydrated! Every time you log a refill, Ocean Bottle funds the collection of 5 plastic bottles that would’ve otherwise ended up in the ocean—at no cost to you! How the Ocean Bottle App Works: Create an Account: Pick a unique username, password, and profile image to kickstart your plastic-collecting adventure! Add Your Ocean Bottle: Scan the bottom of your bottle (where the NFC chip is) with your phone, then select your bottle's size and colour. It’s like giving your bottle its own identity! Log Every Refill: Whether at home or on the go, tap the "Refill Bottle" button and scan your bottle to record each refill. See Where You’re Making Waves: After you log a refill, Ocean Bottle funds the collection of 5 plastic bottles at one of our collection centers. You’ll get to see exactly where your impact is happening across the globe! Track Your Plastic-Collecting Journey: Check back on your refills to find out where, when, and what kind of plastic is being collected—all thanks to you! Stay Hydrated with Reminders: Turn on notifications so we can give you a nudge when it’s time to drink up (and track your plastic-saving progress along the way!). Sync with Your Health App: For an extra boost, you can link the app to your Health app. This way, your phone can help you stay on top of your hydration goals! Environmental Impact: By purchasing an Ocean Bottle, you've already helped prevent 11.4kg of ocean-bound plastic (about 1,000 plastic bottles!) from entering the ocean, and with the app, you can keep boosting this impact! We work with amazing partners like Plastic Bank, Plastics for Change, and Repurpose Global to ensure all types of plastic are collected and processed in the most efficient, socially responsible way possible. Why do we do it? Because together, we can change the tide on plastic pollution. Join the Ocean Bottle Community: Join over 20,000 people who’ve already helped stop plastic from polluting our oceans.
