“If you are following IF, I like the idea of using an app to remind you of your fasting window so you can be consistent,” says Palinski-Wade.

If you want to track your fasting times and keep an eye on your diet, Fastient has some of the most comprehensive tracking functions out there, allowing you to maintain a record of your food intake and stay on top of your overall progress. It features a wide, open interface that leaves plenty of room for you to journal, view your data in easy-to-read graphs, and access your info within the app or on your desktop.

If you want meal-planning advice: BodyFast

APP STORE
BodyFast gives you 10 different IF plans to choose from—and also serves up loads of coaching and meal planning tips. If you’re committed to IF but struggling with the daily mechanics of it, this app might give you what you need to troubleshoot your challenges.
Palinski-Wade says she loves all the support BodyFast offers, but warns that it could be a little misleading. “The BodyFast coach provides tips based on data such as your age and weight-loss goals, but this is not a replacement for working with a medical professional like a registered dietitian who can truly customize your meal plan for your own unique needs,” she notes.
The app comes with a set of free features. Getting the BodyFast Coach will unlock even more tools. Pricing varies, but you can choose from one-month, three-month, six-month, and yearly plans. You’ll have access to over 100 recipes, weekly challenges, and the ability to build a personal plan.

If you like having community support: Vora

This is a pretty standard IF tracking app (providing daily fasting or goal timing and weight loss progress). But Palinski-Wade points out it includes one unique—and important—component: community support.
“Research has shown that accountability and social support lead to greater success when it comes to making behavior change,” she says. “By engaging in a community of people with similar goals, this app may help you stick with your IF plan long-term for the best results.”
So, if you’re the only one of your friends who’s doing IF and you need peer support, Vora might be your perfect fit.
Another great thing about thing about this app is that you can use it for free or upgrade to Vora Pro for just $4.99. The upgrade will give you more ways to track your progress, access to the community forum, and the ability to measure your own statistics.

ZERO
One of the most popular IF apps out there, Zero has all the timers, journals, and tools you need to get started, and is also full of helpful articles on topics such as fasting during quarantine, the best beverages to drink during your fast, and how to get better sleep. Our pros found it easy to use and great for IF novices to lifelong fasters. Sassos likes that the app offers opportunities to rate your mood which generates a “mood graph” on your fasts that you can review and look for certain patterns based on what and when you are eating.
The basic app is free, but it will prod you to upgrade to Zero Plus ($69.99 a year or $9.99 per month), which includes guided fasting with a coach. “[This app] game-ifies intermittent fasting. It sets goals, it tracks other things like sleep, weight, etc… there’s a journal function which is great,” wrote one reviewer. “It tells you what your body is supposed to be doing during that time frame of fasting…I have the free version and still, it is very useful. They do not bait you into buying their product. Real honest and a huge plus for me.”

Another super-popular option, with over 23 million downloads, this German-based IF app allows you to frequently switch the type of fast you’re on depending on your goals and needs that day or week. It also offers weekly challenges and trophies to keep you motivated.

Starting at $16.99 per month, you’ll also get access to a personalized coach. “I like that this has a few options for your eating schedule, so I’ve been able to adjust when things are hectic rather than sticking to a specific window, and it gives me alerts about where I’m at in my day, ” says one user, who uses the free plan.

Teamwork is the key feature of this IF app—you can create social circles to share your fasting experience with friends which Sassos says can keep you more accountable. This app also uses visual graphics to show when you’re going into the fat-burning phase of your fast, which is a big motivator for some users.
You can join for free; personal sessions with coaches will cost you around $30-$60 for 30 minutes. Group coaching is also available for a reduced cost. “It’s really nice to have a visual aid to a fasting regimen,” wrote a reviewer. “I like seeing my cumulative fasting time and how long I’ve been in ketosis each week. I can also see when my husband is fasting and plan our family meals accordingly or just give him moral support.”
