Zero - Fasting Tracker

By Courtney Circle

Open iTunes to buy and download apps.

Description

Zero is a simple fasting tracker used for intermittent, 5:2, and circadian rhythm fasting. Choose your favorite fasting protocol and Zero will track your ongoing progress. Export your data to a spreadsheet for complete control.

Zero supports the following fasting types:

Circadian Rhythm Fasting: Based on the research from Dr. Panda (Salk Institute), participants are encourage to fast 13 hours per day, starting each fast at or before sunset. Zero uses your location to calculate the daily sunset time for the best possible accuracy.

Custom Intermittent Fasting: Setup a custom program to meet your fasting goals. You choose your fasting hours per day, and days per week.

5:2 Fasting: Based on the 5:2 fast diet, participants partake in five days of normal eating, followed by two reduced calorie fasting days.

Not bad

Thoughtful app. Clean-looking design and easy to use, but given the other distractions in my day, it would be helpful to have a reminder to check in and out - which I often forget to do even when I accomplish my fasting goals. The inability to revise start/stop times means I can't input my fasting times when I've forgotten to sign in on a particular day. This obviously affect tracking. The recommendation to start fasting as close to sunset as possible is not helpful since fasting by day or night doesn't affect the outcome as long as one is consistent. Additionally, "sunset" depends upon season of the year, where one lives, etc. If you live in an area where the sun sets early - say 3 or 4 in the afternoon- it may well be too early to start fasting (assuming you care about this nominal bit of advice). Lastly, more references to the science would be helpful. Some of the great pioneering work has been overlooked (starting with animal research from the 1930s upon which calorie restriction and fasting has been based, the experience of the Biosphere 2 crew members, and so many other researchers, including Walford, Fuhrman, etc.). I'll keep using the app when I remember to, but it needs a bit more work. Good effort though!

Great UI but inability to edit times is a bummer

People who give this negative reviews because it's "just a timer" miss the point: there can be tremendous value in timing and tracking things like IF. This app makes the easy and is beautifully designed. The links to the science and educational content are also useful.

However, being unable to edit start and end times as well as being unable to edit previous days is proving to be far more frustrating than I initially anticipated. I frequently forget to hit start right at my last meal—and this renders the timer and tracking worthless if I can't change that.

An easy problem to fix in the next release and would make this app very usable.

Surprisingly it motivates me to fast

I've recently gotten a bit lax on my fasting practice (I try to stick to the 12pm-8pm meal window). I didn't have high expectations for this, but have found this app results in spending less mental cycles/energy thinking about when I started/stopped eating. And it's motivating to see how much time has passed and how long I've fasted. This has resulted in me sticking to fasting more and, in turn, has reignited a bit of motivation to fast. Highly recommend.

Improvements: have the Science section include nicely/natively formatted text articles. I don't want to watch videos.
