REBO Bottle LED light ring meaning chart:

 The accuracy of the measurement will depend on having your time of flight lenses in the inner part of the cap clear of any water droplets. If you see that there are water droplets, remove them with a damp cloth or with your finger. This will improve the accuracy of the measurement. You can also plug and unplug the bottle to the USB C cable connected to power, this will trigger a reset of the bottle. If you are still having problems after doing the above steps, click on the chat icon on the bottom right of this page so we can guide you with troubleshooting.

No worries! You can manually input what you drink outside of the bottle to keep up with your hydration statistics.

 Your REBO will keep working normally even if it is not connected to any phone. Once the connection is back, the bottle will upload all the accumulated data to the app. The memory in the cap is able to store drinking logs for up to 3 days.

REBO is thought of as a personal item, therefore each bottle is synced with one account only. If the bottle is used by more than one person, the intake is attributed to the person synced with the bottle. 

Unfortunately this is not possible in the current version of the app, but we may add this feature in the future.

REBO is thought of as a tool for hydration and we recommend using it with water for its full functionality. You can drink coffee and tea from the bottle, but it will not track these liquids towards hydration as due to the caffeine presence these do not count to meet your hydration goal. This is done by switching off the laser sensor when high temperatures are detected. We do this also to prevent the technology from getting damaged by liquids with high temperature. 

In order to ensure the correct functioning of REBO, and its leak-proof closure, we do not recommend using it with sparkling water. If you still decide to do it, we cannot guarantee the correct functioning of the closure as sparkling water will create a lot of pressure in the bottle which may lead to leakage. Also be aware that the bottle will make a lot of noise “champagne effect” when opening it when there is sparkling water inside.

We have an algorithm which helps us determine what should be counted for the creation of a PACC. Hot liquids for example do not count as drinking them with REBO does not necessarily lead to the prevention of the creation of a plastic bottle.

Yes. We recommend washing it well to avoid influencing the flavor. Note that the bottle is dishwasher safe, so you can easily wash it. The cap on the other hand can be washed under running water but not in the dishwasher.

Yes, the stainless steel bottle is dishwasher safe, but only the bottle! The smart cap cannot be placed in the dishwasher in light of the electronic components which would be damaged. The cap is water resistant which means that it can be washed with a damp cloth, exposure to running water should be limited as much as possible.

No! Due to its embedded technology, the smart cap is NOT dishwasher safe. It is water-resistant and can be washed with a damp cloth, exposure to running water should be limited as much as possible.

The REBO App is available on AppStore and GooglePlay.

The REBO App is compatible both with iOS (11 and above) and Android (6 and above)

Use this chart to determine your activity level.

Yes. You can do this easily from the app settings, but If you link the app to Apple Health or Google Fit it will change dynamically if these apps are updated with the changes. 

Personal information is handled in a fully anonymized way that is GDPR compliant. We believe the European GDPR is the strictest standard to guard your information, which is why we apply it everywhere.

Yes, alerts on the bottle can easily be switched on and off in the settings screen of the app. You can also set the hours at which you are willing to receive the alerts. For the time being you are not able to change the frequency of the alerts, but we are working on making it possible soon. 

Yes you can do this by allowing access to Apple Health/Google Fit where the historical hydration levels will be stored. You can click on the Apple Health/Google Fit icon in the hydration screen and quickly access it.

Unfortunately this is not possible in the current version of the app, but we are considering adding this feature

Unfortunately this is not possible in the current version of the app, but you can consider using the same cap on different bottles only carrying with you the cap.

We have a proprietary anti-fraud algorithm that calculates your plastic savings, and is vetted by our certification agency GoldStandard (to learn more about the certification process click here)

Unfortunately this is not possible in the current version of the app, but we are working on adding this feature

Unfortunately this is not possible today, but we are working on it.

We use a user generated API which has mapped more than 230 thousand water fountains in the world and is regularly updated with new fountains.

Unfortunately, there is not a one-size-fits-all answer. Everyone is different. That is why it’s important to use a daily hydration tracker that creates a customized hydration plan according to your personal characteristics.

Our bodies have a way of telling us when something is wrong. Signs can be infrequent, dark urination, dry mouth, constipation, headaches, frequent sickness, dull or dry skin, thirst, and increased fatigue.

Numerous studies show that drinking water increases the number of calories you burn. Since water is naturally calorie-free, replacing it with other beverages - drinks typically loaded with sugars - means you consume fewer calories. As water is satisfying to the body when we’re properly hydrated we’re less likely to overeat, thus consuming fewer calories altogether.

Studies show 70-80% of the body’s water intake should come from the fluids we drink, leaving 20-30% to be absorbed in the foods we eat. 

Offset credits are used to compensate for environmental outputs. They are increasingly popular among corporations and organizations wanting to improve their environmental impact.

Renewable energy is a great example. When it’s not feasible for a company to invest in its own solar, or wind, projects, it buys green credits to offset carbon-emitting energy usage with a renewable source. Many companies - including us at REBO - buy carbon credits of this nature to be Carbon Neutral. In other words, to offset the amount of Carbon that our existence generates.

Giving the growing threat of ocean plastic pollution, REBO offers a solution for minimizing plastic-footprints. Our take on offset credits are called Plastic Avoidance and Collection Credits (PACC), these provide an incentive for REBO users not to generate more plastic (Avoidance), and fund the collection of already existing plastic waste (Collection).

Technology embedded in REBO Bottles allows plastic savings to be 3rd party certified by the Gold Standard, ensuring the impact and credit-worthiness of environmental projects. Issuing PACC enables us to continuously fund ocean-clean up efforts.

The Gold Standard certification process reconciles data collected by the REBO bottle with the number of Plastic Avoidance and Collection Credits (PACC) REBO can issue and get sponsorship for. Our ability to continuously generate a trustworthy source of credits allows our sustainable business model to support itself. 

Yes, REBO pays in advance for plastic collections and then it attempts to cover the cost by selling PACCs. The proceedings of the sale of PACCs are entirely used for funding plastic collections with no commission whatsoever to REBO. In the case of not fully covering the cost, REBO pays for it, always maintaining the 1 bottle drunk, 1 bottle collected promise.

Additionally REBO sponsors plastic waste awareness/education campaigns through its partner Project Rescue Ocean.

REBO is also a proud member of “1% for the planet”, the international network of businesses that commit to donate the 1% of gross sales directly to environmental nonprofits. To date “1% for the planet” has invested over $250 million in environmental solutions (to find out more visit our certification page) 

According to the World Economic Forum, there are ~150 million metric tons of plastic in our oceans today. Each year 8 MILLION metric tons of plastic pollution enters our oceans. That’s equivalent to one city dump truck per minute. By 2025, the ratio of plastic to fish will be 1:3, and by 2050 there will be more plastic in the ocean than fish. Studying these shocking stats is what lead us to start creating REBO.

Plastic islands refer to masses of aggregated plastic pollution in the oceans. As the ocean has become a dumping ground for plastic pollution, we have five plastic islands each with a surface larger than France. Our planet's plastic islands disrupt biodiversity and marine life, and its impact is felt around the globe.

No. We recognize plastic as an important part of the global economy. The real problem is our current usage and lack of recycling. Most plastics are used once (single-use plastics) and thrown away. Consider that it takes 450 years for a plastic water bottle to degrade. We have made progress in recycling plastics, but today only ~9% of plastic gets recycled worldwide. 

Truth be told, as a young start-up we could not afford to be Cradle-to-Cradle certified. But, we followed the principles to design our product to be environmentally responsible. If you look next to the USB C plug, you can see that there is a screw that enables professionals to fully dismantle the cap and separate its components. Watch out, once open the warranty is void.

Yes! REBO bottle is recyclable. 

We are developing take-back programs in different markets. Please check our website for the most current information click here.

REBO’s smart caps come with a rechargeable lithium battery and have an integrated USB C port to make charging easy. We chose REACH and RoHS certified lithium batteries because they are the longest-lasting battery, and the most sustainable option we could find.

Depending on the frequency of its use the battery will last on average 2 weeks. We are working on optimizing battery life in order to make it even more long lasting.

It will take roughly 2 hours in order to fully recharge your smart cap

We use time-of-flight technology. An infrared laser, harmless to the human eye, sends a light signal that hits the liquid and then returns to the sensor. The time it takes to bounce back is measured, recording changes in water levels. We do this over 10 seconds in order to get multiple measurements, make an average, and send them to the app. This is why it is important to leave your REBO vertically on a flat surface for 10 seconds, this enables REBO to get an accurate reading.
