Window is different from other Intermittent Fasting apps. Instead of tracking your fast, you track the time to eat -- your Eating Window!

Window is also the only fasting tracker that lets you track your weight right in the app! You can log your weight and view a graph of your seven-day moving average. Window helps you understand how your eating habits relate to your weight loss journey.

With this app, you can:
- Schedule a daily eating window or open a timed window at any time of the day.
- Get notified when your window opens and closes.
- View the progress of your current eating window.
- Track your weight over time and view a graph of your 7-day moving average. Works with Apple Health to sync data with other apps.
- Add notes to your windows to log your daily eating habits

Happy tracking!

So helpful!!

I love this app. I use it every single day. I am doing the OMAD but it does help to be able to leave a note when I eat a particularly high carb meal or I want to remember that I went somewhere in particular and that’s why my window might have been open longer than another day. I prefer to use the flexible window because of my work and family responsibility don’t always go hand and hand with a reliable time routine. The ability to have a scheduled or a flexible window is a great option for people who never quite know what the day will hold. Plus I never know if I’ll be satisfied after an hour or if I’ll need a little extra food that day, but I don’t feel the need to keep eating because my window hasn’t closed yet. This app helps me not only keep track of my window and fasting time, it also helps keep track of my weekly (sometimes daily) weights. It not only gives me a place to log in my weight, it also has a very clear and easy to read graph above it tracking my progress. When I haven’t lost much or barely an ounce or two and I start to get down about it, I look at the graph and it really is a pick me up to see that the line of the graft is still going downwards. I would recommend this app for anyone who is entering the IF or OMAD lifestyle. So much more handy than caring a notebook around.


An essential part of my IF life!

I rarely pay for apps and have never written a review. This one is the exception!! It’s the only Intermittent Fasting app that lets users toggle between fasting and eating window durations - both in the calendar overview as well as in looking at user stats. And the fact that it is also a weight tracker, including moving weight averages, is an added benefit. I’m eagerly awaiting the update with Apple Watch integration. But until then - it’s still an amazing app.


Works well with the Fast-5 program

Or with any fasting program: 8/16, AD, etc. Statistics are easy to calculate. You can monitor your fasting window or your feeding window and you can either schedule your windows or just check off when they start and end. I love the average weight feature that tracks your average weight and overlays it along your feeding window time. Shorter feeding windows prompt more weight loss—track it for yourself!
