I did the 28 day FMD & used the book & app. I took a 3-week break using the Cooling for FMD book. Kept at same weight. Love the science. Now I started the 14-day fast start to lose my final 5#, so I bought the big tubs of Ph1-2-3 Shakes. Turned to the app to track my 14-day journey. 1. It doesn’t let you add a shake for a meal, only to BUY product. 2. It doesn’t have the recipes listed in the 14-day fast start, so it was useless. I suggest a complete overhaul of the app (it’s obviously ancient) w integrated permission levels to reflect Member access, 28-day option, 14-day FS option, 7-day, Burn, Revolution, etc, etc. include recipes, tips, reminders, etc. As it is now, the app smacks of a dominant commercial focus, with little of “Hailey” present. This is not the sense I got from the book & website, and it’s shameful. Hailey, are you listening?

This app is a great companion to the cookbook and makes it easy to track you day and stay organized on what to eat/ what you need to buy. I agree with some of the other reviews that it could use some updating. It definitely needs a weight loss graph or tracker of some kind to be able to see your progress. Also you should be able to add by meal to the grocery list as well as by day and then when you pull up your grocery list it should have a combined categorized list. For example instead of telling me I need 1 1/2 apples three different times it should just say 4 1/2 apples. The next thing that bothers me is there are meals on the app that are not in the cookbook so it would be nice if it would provide the recipe or a link to find it. The daily tips are great but I would like to see more information on why certain foods are only for certain phases even though it lines up with her plan. Brussel sprouts for example, why only phase 3 when veggies are unlimited all the time? Overall though the app is definitely a good tool to use and this diet so far is truly working. Shedding pounds quickly and I’m not hungry in the process or craving anything in particular!

I think this app is seriously underrated I strongly recommend it as a fundamental part of the fast metabolism diet; it made the whole process of meal planning and shopping so easy that I am still using it two weeks after my 4-wk diet is over (to awesome results btw). As of possible improvements particularly in light of recent iOS changes, I would strongly encourage the developer to include read (particularly for weight) and write (for water and nutrition in general) to Apple Health app. Logging of water could be streamlined by adding iOS13 per-app shortcuts or by reading info from Apple Health. Regular water reminders instead of once a day would be helpful for the hydrophobes among us. I still think that the Meal Map tab should open automatically on today’s meal. Also the profile should include general food diets such as vegan or vegetarian, etc to automatically filter available foods in the list, which requires a slow item by item selection. Still overall a great app, don’t stop improving!

I stumbled across this three years ago. I was overweight and my husband was dangerously overweight with type two and other maladies exacerbated by the poor way that he ate. I've had to be more careful about things I ate due to Crohn's and a stenosis in the gut where they removed a portion and put me back together. But we were both in need. I showed him the article which I probably found in a woman's day magazine.I was shocked when he told me he believes he could do this. Together we lost a ton of weight. Life happened and we derailed due to family death and sale of home and a huge move which caused less time to cook and pay attention to our bodies. I lost my hubby in May, I continued to lose weight but I've put on about eight pesky pounds and I need to eat better so I'm starting this again. I can't say ENOUGH about the energy we had during the months that we followed this plan. From the bottom of my heart I thank you. It's simple to follow and though there are a couple days where your mind thinks you're depriving yourself, the other five days make up for it. If you want to lose it, this IS the key. Tricking your metabolism. Don't go your whole life feeling miserable and not liking how you look like in the mirror. I was old when I started this. I regret not learning about it years ago. This is it and it was inexpensive. You feel a difference from week one and it only gets better. Highly recommend!!
