Keeps on crashing making it unable to use properly. It crashes in most situations (most often when the app loads).

It is beautiful but it does not react to my footprint calculations very well- if I marked myself vegetarian, it should not give me the option to try vegetarian recipes as an action. Or it should give me an option to mark that action as something I already do. Also, the times per week setting per action does not seem ideal for every type of action (ie why try vegetarian recipes x time per week as an action but not "dont eat meat for x weeks" in general? the 2nd seems more effective to me)

I would have tried this app, but I refuse due to a bug in the Terms of Service and Privacy Notice page. There is a button missing for: Accept the selected only. The only option provided is: Accept All. Sorry, no I won't. See ya.

Thank you for your feedback! It is possible to select what data you allow the app to track, and the app doesn't track anything before you've given your consent, in accordance with European privacy regulations. We will update the page content to make it clearer!

What's new

We've added the possibility to join an organisation within the app. Thus, our partners will now be able to form their own groups and track the group's progress. If you want an organisation code for your own organisation, don't hesitate to reach out to us!

We've also done some bug fixes and UI improvements to offer you a smoother user experience.
