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.

Worth the price! Trust me!

I never buy apps, especially health ones. But since starting fasting, I wanted to find something to help me keep track of my fast on the go. I downloaded a bunch of free ones and they weren't what I wanted.

Window is very flexible and user friendly. You can set daily reminders for when your fast ends and begins. Lots of times I see it pop up and I'm able to check in with myself and change my Window to later because I'm not hungry yet. It's much easier than watching the clock waiting for the fast to be over, allowing food and time to be in control. Just set your times and you'll be reminded. So forgetting about eating time helps you be more engaged with your body.

I love how you can track your fast, see it on the calendar, and see your weight on a graph. It also syncs up with the Apple Health app. Best part is the author of "Delay, Don't Deny" Gin Stevens' son made the app. Definitely worth it when I seen that. Great book and happy to have an app to assist me further.

I Never Pay for Apps

I found this app by reading Delay, Don’t Deny written by Gin Stephens. Her son developed this app and she recommends it in the book. I never pay for apps but since I liked Gin’s philosophy for intermittent fasting best I decided to get it since I didn’t see very positive reviews of other apps. I’m SO GLAD I got this app! So user friendly and it keeps perfect records of your fasting / eating window times. I am really looking forward to seeing what my calendar looks like after I get a few months of data on it. According to Facebook the developer/designer of this app worked or interned for Apple. The minimalistic design reflects that in my opinion. Worth the money! If you are wanting to practice an intermittent fasting lifestyle you NEED this app!
