UK App access: The Cleo app is no longer downloadable in the UK (but only until next year). If you're an existing user, you'll still have access to the app. But some features won't be available (just for a little while). Why? 99% of our users are based in the US - where financial health is often overlooked. We've decided to shift our focus to where we can provide the most value and make the greatest impact for users who need it most. Then we'll be able to apply what we learn to better support our UK users in the future.
