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.

Verdict
The clearest difference is in-app purchases: CO2IN at none against Trypup's 10. CO2IN also leads on device support (3 vs 1). Trypup's advantage is update cadence (every 6 days vs every 2 months). On price, ads and iOS requirement there is nothing between them.
