What's New in Zero

7.14.0

September 7, 2026

More ways to make Zero yours — and share it with friends. This update brings more flexibility to your daily experience, a new way to share Zero, and thoughtful improvements throughout the app. • Share Zero with a Friend: Health goals are better with a little accountability. Invite a friend to try Zero right from Settings, and when they join through your link, they’ll get a 30-day free trial of Zero Plus. • A More Flexible Fasting Timer: Choose between a full or compact timer depending on what you want to focus on. Keep fasting front and center, or free up space to see more of your daily progress. • A More Cohesive Zero: We’ve refined onboarding and updated buttons and other interface elements throughout the app for a smoother, more consistent experience. • Logging Improvements & Bug Fixes: We’ve made more of your most-used logging options accessible at a glance and fixed an issue with date of birth selection for some returning users.

Forced subscription and 5 minute survey

Im trying to get a simple fasting app and immediately upon opening after download this app im required to make an account, enter all my details, and after 5 minutes of questions and life interview im required to pay a subscription with no option of declining. Apps like these are obnoxious and a waste of time.

Old version was better

The old view or display of all months together was way better and more encouraging than viewing month by month alone , i am so frustrated from this new update.And also what’s average hours of fasting during the month? This is frustrating too.
Please please go back to old view and total hours of fasting during the month accumulated. I was a big fan of this app now i am thinking to uninstall because of these unreasonable changes. This is not an update this is stupid.
