While intermittent fasting isn't a magical solution, it’s an effective weight loss strategy for those who can commit to it. If you’re dedicated, these fasting trackers can help you stay on track by reminding you of your fasting and eating periods, and by showing your progress over time.
All fasting apps essentially serve as timers. You set your start time, and they count down until your next meal. When you’re in a feeding window, they’ll show you how much time is left. They can be as basic or as advanced as you prefer.
The best all-around app: Zero
Zero (available for free on iOS) is a popular choice among intermittent fasters. It offers an intuitive start screen where you can select a pre-set fasting schedule (such as the common 16-hour fast with an 8-hour eating window) or customize your own. The app tracks your progress, sends you notifications when your fasting period ends, and features a dashboard that displays your average fasting duration, multi-day streaks, and weight trend (if connected to the Health app). The design is simple, making the app user-friendly. It's only available on iOS (though we missed the Android version—Vora is a similar well-loved app for Android users).
Simpler fasting apps: Fastient, FastHabit
For those who don’t need advanced scheduling, Fastient offers a straightforward experience. You can start a fast, optionally set a goal, and add notes on how you're feeling throughout your fast.
FastHabit is even more basic: no account needed, just a timer for your current fast and a log of your past fasts. To get reminders for daily fasts, you’ll need to upgrade to the $2.99 version.
