InterFasting - Intermittent Fasting App


Intermittent fasting is a dietary management method where you cycle between periods of fasting and eating.
By maintaining a fasting state, it regulates insulin secretion and triggers a ketogenic state where your body burns fat as its primary energy source.
While it is highly effective for weight loss, intermittent fasting also plays a significant role in improving overall eating habits.
InterFasting is an intermittent fasting tracker designed to help you manage and log your fasts seamlessly through timely notifications.

16-8 Fasting

The 16-8 method involves fasting for 16 hours and limiting your eating window to 8 hours within a 24-hour day.

5-2 Fasting

The 5-2 method involves eating normally for 5 days a week and fasting (or severely restricting calories) for the remaining 2 days.

The Fasting App I Consistently Use

I've tried so many different fasting apps to track my intermittent fasting, but this one is by far the most straightforward, clean, and no-nonsense! I reached out with a couple of questions, and the developer was incredibly kind and warm in their replies—it really touched me. Happily using the premium lifetime membership now. You're the best, developer!!!!!!!!!

Highly Recommended

I almost gave up on day 1, but just as I was about to quit, I got a notification saying my body was entering the fat-burning stage, which kept me going! The periodic stage notifications are so fun, and I think it's the best diet app I've ever used. Also, the premium service isn't a monthly recurring subscription—it's a lifetime access with just a one-time purchase. The price is very reasonable and it feels like an amazing value! It's such a great app, please keep it up! ㅠ.ㅠ

Simple Yet the Best and Most Reliable App

Famous diet apps like YAZIO or InOut also have fasting timers, and I used them at first. However, YAZIO's widget has about a 10-minute delay and doesn't update under a minute, and InOut doesn't even have a widget yet. But InterFasting updates in seconds right on the widget and is incredibly intuitive. Other features are secondary; it perfectly focuses on showing exactly how long I've been fasting. I sent a message late in the evening about an error, and they replied immediately with a solution, so I just had to give it a 5-star rating. I only found this app during my maintenance phase after finishing a 2-month diet, which is the only bummer! ㅜㅜ

Absolutely Perfect

Since it's a one-time purchase rather than a subscription, I bought the premium version and have been loving it. Tracking fasting hours, workouts, weight, diet, water intake, meal photos, and even progress pictures... being able to log everything for dieting in just one app and see it at a glance makes it the perfect app for dieters ㅠㅠ It's the absolute best among all apps, I deleted all the others. I will succeed in my diet, thank you! 💕
