Join the CO2IN ecosystem and help the climate from your phone! CO2IN gives you the tool to reduce your carbon footprint. Our app allows you to reduce the amount of greenhouse gas emissions released into the atmosphere and at the same time support the green transformation. Calculate your carbon footprint Our carbon calculator will quantify your carbon footprint in just a minute. Based on your results, you can immediately acquire the amount of CO2INs that correspond to your annual carbon footprint. Reduce greenhouse gas emissions Every CO2IN in our ecosystem reduces the ability of European polluters to emit harmful emissions into the atmosphere. CO2IN gives the ability to directly influence our climate into the hands of each and every one of you. You will support green projects The money spent on CO2INs are used to purchase EU emission allowances. The proceeds from their auctions go to individual EU countries, which use them to support climate projects. The money that you put into CO2IN will help where it is most needed. We will accelerate the transition to a carbon-free economy Thanks to the removal of emission allowances from the market, you can positively influence their price. That will lead to greater investment in carbon free technologies. Companies will be financially incentivized to reduce their emissions faster, rather than pay more for allowances. Send and receive CO2INs CO2INs can be instantly sent or received from friends and selected merchants within our ecosystem. Transfers can be made to a specific user, or through a QR code. SUPPORT - DO NOT HESITATE TO CONTACT US We have a trained customer support team that will be happy to help you with any problems. If you have any questions, encounter a problem or have an idea to further improve the app, let us know at support@co2in.com.

Try dog care for real β€” walks, training, health and costs. Without the risk. Already have a dog? Dog at home mode gives you a dog passport and diary, vaccination and deworming reminders, and reads vaccination-booklet entries from a photo. Records for one dog are free. The 30-day challenge: a month of dog care, day by day, for practice. At the end you'll find out whether a dog is right for you, see what happened during the month and take a final care quiz. Many dogs end up in shelters because their owners never realised what daily care actually takes. Trypup gives you the chance to find out BEFORE you decide β€” not after. Pick a breed, name your dog and look after it like the real thing: GPS walks β€” real routes with time, distance and a check that you actually went outside Daily care β€” feeding, play, grooming, rest; your dog's stats react to how well you care Training β€” 9 commands that unlock step by step; every breed learns differently Health β€” a vaccination calendar and realistic monthly and yearly costs of owning a dog Learning β€” articles on adoption, choosing a shelter and the 10 questions to ask yourself before getting a dog Life timeline and badges β€” follow milestones and progress Co-ownership β€” share the care with your family (Premium) Trypup is not a game you win. It is an honest test: can you do it every single day, even when you don't feel like it? Neglect your dog and it leaves for a shelter β€” just like in real life. Turn on Dog at home by choosing β€œI already have a dog” on the first screen, or any time in Settings. It also has a care plan, first aid and directions to the nearest vet. Try dog care before you get a real dog. β€” Trypup Premium (optional): β€’ Monthly β€” auto-renewing subscription, billed monthly β€’ Yearly β€” auto-renewing subscription, billed yearly β€’ Forever β€” one-time purchase, no subscription Individual dog breeds are also available as one-time purchases.
