Terrible app. When I scan and save foods I can not find them again easily using the search bar. I have to either rescan everything, or if I don't have the original packaging I have to scroll and scroll through my list of previously scanned foods to locate each item that I want to log. It is extremely time-consuming. I have paid for the app, customer service just tell you to repeat the same steps over and over. No matter how many times I tell them that it still doesn't work, they will not listen.

app is complicated and there is inadequate instructions so you have a lot of trial and error before you get it right,a mistake is easy to make and put you out of ketosis, when adding food there are lots of entry's of any particular food with sometimes widely different carb ratings even allowing for the different type of servings especially those added by "members" having said all that I couldn't do without it. with a few tweaks it could be a 5* app. in conclusion,I would recommend it .

I decided to sign up for the quarterly subscription, as it seemed I could do everything in one place, rather than use separate apps. Turns out it was a complete waste of money. The fasting feature, in particular, is way too basic, and I don't get a fast total display, which ALL other (free) fasting apps do. Plus it only gives 15 minute increments for start/end time. I want to just set it running when I start my fast! So I am still using the app I had before. I'm extremely disappointed!

Thanks for your review! We've been getting great feedback from our users on improving our Fasting feature and keeping track of all these requests. Yours is one that we have seen before. We are working on our development plan to see when we will include and release additional functionality to the fasting features. Stay tuned!
