What’s New

Version 5.0.0

Hello, Zero crew -

This release sets the foundation for transformative updates you’ll see over the coming months as we expand Zero to help you balance your health beyond just fasting. We’ll always help you with your fasting practice, and now we’ll also help you build habits around the Four Pillars of Health; nutrition, activity, sleep, and restoration.

We’ve made it easier to track your habits, right from the Today tab — simply tap on the “+” at the top right to add your weight, latest activity, or current mood. Your fasting calendar is also quickly accessed via Today — tap on the streak icon at the top left to check in on your recent progress. Your calendar is temporarily excluded from the Me tab, but it will return soon, and the Recent Fasts chart is back, so you can easily check in on your latest fasts.

We’ve also updated the Coach experience and brought the primary features to the Today tab. Soon, you’ll have a wealth of health guidance at your (literal) fingertips, accessible before, during, and after your fasts. The Coach tab and weekly plans have been removed, but you still have easy access to set Fasting Reminders for each day of the week. Just tap into Settings on the Me tab, and then turn on Notifications. From there, you can set custom reminders to match your fasting goal.

Updating your fasting goal is now easier than ever — just tap the button at the top right of your Timer ring to choose a new goal or create a custom preset.

We also fixed bugs some of you were seeing when ending or editing a fast or logging your biometrics.

Stay tuned for more updates to the Zero experience based on your feedback, and please reach out to our Support Team at zerolongevity.com/support if you have any questions.

Works. 30lbs in 2.5 months

I tried keto, I tried them all. Ended up binging and gaining more back quickly. Found fasting and really knocked out the cravings. With Zero it’s really easy to follow your progress without feeling like you’re staring at a clock waiting to eat again. The articles help ease your mind in the beginning knowing that your hunger pangs and other side effects are common and have reasons. Also how to avoid them and get past the fasting wall. I love the timer and how you can count up or down. I count up because I like seeing how far I can push myself within reason. Counting down makes me want to eat as soon as it hits 0:00. The app has some great tracking features and syncs up with apple health so it takes down the data from my smart scale. Nice knowing that I don’t have to manually enter everything every time. A welcomed improvement would be a way to change the theme of the app to keep it fresh or personalized. Different colors etc. this is a small ask for me. Overall I love the app and have lost 30lbs, 6%body fat in 2.5 months. Tbh I haven’t exercised much at all. Just having my body do what it does and use the energy I’ve stored away for years. But now losing the weight of nearly two full size dyson vacuums, I have more energy both mentally and physically that I now crave to get out and do more

Literally life changing!

This app has been literally life changing! I accidentally stumbled upon it, just wanted something SIMPLE to log my fasting hours when I first started learning about intermittent fasting but it has sparked my interest in all things related to fasting and health. Im not able to afford paid version and Im extremely grateful that the free version has enough basic information and tracking features to inspire change and at least plant that seed to help people want to learn more, and to want to live with more insight, regardless of economic situation. I was that moron.. the one watching with suspicion while wolfing down pizzas, thought people fasting were just weird food hating extremists. This app has been a revelation, and has been instrumental in opening the door to a new world to me so to speak. It has been invaluable in changing my attitude towards food, fasting, meditation. If you have the means to buy the paid version do it, it will be a small investment for what you get. For me sadly the the price point for the paid version for this and the podcast is not doable but the free version can be very eye opening. Dont just log fasts like I did at first. Dive in and discover everything on the app thats available for free and listen to the podcasts. Fasting and tracking my glucose is now my normal way of life. Grateful.

Used this app to lose almost 70 lbs in 3 months

Then the pandemic happened and I stress ate my way through. Now there’s a vaccine coming and I want to get back on track again. I highly recommend this app for weight loss, health, energy, anti-aging, etc. I wish I’d known YEARS AGO that fasting was healthy and a real way to stay healthy and fit. We were lied to fir decades, but it’s not too late to take control of our bodies and health!

I tried a lot of apps for fasting and this is the most flexible. You can edit your start time after starting the fast so if you forgot to start the app, but remembered to fast, you’re all set. It has some scheduled routines and a lot of freestyle, so lets you do you. Notifications are inspiring as it shows how many other people are fasting. You can eat a wider variety of foods if you fast regularly with far less negative impact on your weight and health. I don’t feel like a failure or dread coming back to this. I got anew iPhone and it triggered me to get going again. I’m really excited! Join me in a fast today!
