It’s great

I love this app and recommend to others. I am not using the premium version but I still love this app. It alerts me when I am close to or am starting my eating period or fasting period. I get a notification an hour before each starts. I wanted to start intermittent fasting since I wanted to lose weight but without always having to eat healthy and workout. Now I eat semi-healthy and get my workout from my gym class in school. I’ve only used it for one week but I’ve lost 1.5 lbs and I ate cake most of the week and had pizza and everything unhealthy and greasy. Anyway I definitely recommend trying fasting if you don’t want to have the hassle of trying to eat extremely healthy. At the beginning it is a bit difficult but after a few days you get used to it and you aren’t hungry. I use the 16-8 fasting method and skip breakfast. I am a student so I don’t fully skip breakfast but I only eat a small and healthy breakfast. This way I don’t get hungry until lunch.

“Coach” is useless - except if you have (almost) unlimited flexibility

I was surprised and disappointed that the “coach” doesn’t take into account any user preferences. It doesn’t even ask at the beginning of the week which meals are set in stone and the optimizes around that. So, if you’re like me and have family or work dinners that you just can’t move, bad luck. I try to shift the fasting windows to accommodate my schedule but most of the time it’s not even feasible because the “coach” suggests a 36 hour fast which collided with two work dinners... so the only solution they offer is to cancel the whole day and use the joker day?! That’s a joke, pun intended. So, I have to make my own schedule outside of the app which really defeats the whole purpose of the app.
The app claims that the coaching version is more effective because it prevents the body from getting used to a fasting schedule which would make that fasting schedule ineffective. To the developer team: please post some proper scientific evidence for that strong claim. I wasn’t able to find anything that comes even close.
Recommendation: don’t buy the coaching option. There’s no useful added feature. The free version is ok and, well, its free. 3 stars for that.

Developer Response ,

Hi, thanks for your feedback.
We really appreciate feedback from our users and bring all those suggestions to our development meetings.
I'm sure that we can integrate many of those into future versions of the app.
We work hard to make BodyFast better and better every day.
In the beginning of a Coach subscription it might happen that the Coach suggests fasting plans, that don't fit your everyday life. This is because the algorithm does not have much information about you and your fasting habits, yet (available information increases with every fasting week).

+ If you don't like the current coach week you can rate it accordingly (too easy / too hard) after finishing or aborting it and the coach will give you a more fitting week in the next plan.
+ You can also move the fasting periods by pressing the button to change your week layout to fit better into your daily schedule. Of course you can also fast longer if you feel ready for it. But always make sure you rate the week correctly.
+ You can also always choose from the 50 different fasting plans manually if you want to try a different fasting week plan. The Coach will also calculate the fitting weekly challenges for manually selected weeks.
In the current version of our app it is not possible to adjust the lenght of fasting periods. Fasting periods can only be shifted. However, we are working on an update that will allow our users to freely adjust their fasting periods.
Kind regards,
your BodyFast-Team

Expecting more from coach version

Just purchased the 3 month coach version and on my first week using the app. I got the app because of the accountability part of having it remind me when to fast and when to stop and tracking the progress, plus thought the coach version would enhance my experience with personalized tips to reach my goals faster. The major feedback which I have for the developer is the app is lacking flexibility with fasting periods. For example if I want to continue fasting longer on a certain day I can’t record that in the app. Or if I need to cut the fast sooner on another day (life events, how I feel etc) also cannot make the adjustment in the app. Very disappointed with this because I feel like the app doesn’t allow for realistic recording of fasting periods and sometimes it gets too stressful to stay right on track with the coach when personal life gets in the way.
This is my first impression as I am on my first week of fasting. The main feedback to the developer please allow the flexibility to be able to adjust and record our accurate fasting periods so we can be at ease and stress free.

Thank you for your detailed feedback, much appreciated! We have this on our agenda already and are currently working on more flexibility. So stay tuned for upcoming updates!
