Clean interface and insightful questions less to real actionable steps to allow anyone to see how they can cut carbon. The graphics are eye-catching and the layout is user friendly; I’d encourage anyone and everyone to download and see if they can do more to help the planet! I particularly like the “climate clock” feature —> apparently, if everyone lived like me, we’d only have 4 years until the climate clock runs out! Yikes! I better take more action… Thanks Giki! ### 5/5 — This is fun…. *2023-03-02, version 1.0.4* So easy, and I can see I have a lot of points for the steps I have already taken on my journey, but more to do ! ### 5/5 — Great initiative! *2023-03-02, version 1.0.4* They really helps explain how we can all do our bit. Great user experience! ### 5/5 — Great for seeing my footprint & making a difference *2023-03-02, version 1.0.4* Love it, highly recommend! ### 5/5 — Live more sustainably! *2023-03-01, version 1.0.3* Giki Zero has been transformative for how I live my life and knowing what I need to do for the planet. It's empowering to have a mini roadmap for my own personal journey and learn more along the way. ### 1/5 — Might be good *2023-02-28, version 1.0.3* But who knows huh? I can’t sign up as it’s so buggy when it switches to the website. Why can’t I sign up in app? It never goes through and hangs. Managed to sign up on website via browser and now it won’t log in on the app Just hangs. Why can’t we use this app without logging in? Would be much better for users if they could actually see the benefit to your app before you start farming their data from the offset. Have more respect for potential users and allow them to skip reg and check out the apps features FIRST! ### 5/5 — Helped me think about my carbon usage! *2022-08-01, version 1.0.0* I never really knew where to start with cutting my carbon as all of the ‘common sense’ steps I felt was doing (turning off lights, not wasting water etc.) but Giki has helped me take more effective steps such as swapping to a bank that doesn’t support fossil fuel projects that I wouldn’t have instantly thought of. Having a tracker of my carbon score has also been really helpful in keeping me on track and motivated to take even more steps. Would totally recommend for someone looking to live more sustainably! ## Frequently asked questions about Giki Zero ### What is Giki Zero?
