Good, but could use more

I honestly like this app and think it is a fun way to loose weight. I don’t have a problem with the red green yellow light system, like most people are having. Although, one thing I would suggest, or if you could explain it to me, is a video about how the portions are measured and which foods get which portion sizes. For example, I know somethings portions are a whole hand, some are a fist, and others can be just a finger. Although, I don’t know which food goes to which portion. Also, I think there should be a barcode scanner so you can scan some of the products you eat because I sometimes I eat a granola bar for breakfast and it’s more of a healthy one but the only one that comes up is an item that is red. I just feel like that would make everything a whole lot easier. I hope you can get back with me and respond, and I hope to see these fixes. If not totally fine.

Please do not use this

Please please please do not use this app or encourage your children to use this app.
When seeing this app release, I was outraged. I paused, calmed down, opened my mind and tried the app for myself. My conclusion is this app is dangerous, propagates weight stigma, encourages a diet mentality and could lead to a poor relationship with food and food intake, disordered eating, or eating disorders.
I am in eating disorder recovery, and I confidently say this app would have been devastating to me, had I found it when I was young or in my disorder.
A healthy relationship with food can not be obtained, when you look at food as good or bad, healthy or unhealthy, green or red. Labeling food and controlling intake at this minute level is a breeding ground for a disordered relationship with food.
Teach your kids that food is food, that their health is not directly related to their weight. Teach them to eat when they are hungry and stop when they are full. Teach them talk about what they are feeling, recognize emotion, and healthy outlets for emotions and movement. Show them that they don’t have to live by color categorized foods, a diet and exercise plan, a burn to earn mentality or a number on a scale. And for the love of all things good in this world do not teach them that raisins, Apple juice, pistachios, chocolate milk and peanut butter are food to be afraid of! (All red foods in the app - that according to my plan I was only allowed to have 5 of).

UI leaves a bit to be desired

I’m trying to keep track of my 5-year-old’s nutrition and weight, as she was classified as overweight at her last appointment. Setting up the app as a parent, I created her profile but it automatically assigned her my last name even though she has her dad’s last name, and it just named her “Kid1”. I don’t know if I missed something when I made her profile, but regardless, there is no way for me to edit her name. I thought perhaps logging onto the site on a computer would let me edit it, but it doesn’t. So now I’m stuck with a profile that says “Kid1”, no buttons that allow me to delete or add profiles, and a clunky user interface with very limited options, which would be fine for a kid using the app but which isn’t so great for the adult trying to use it. I have used WW off and on, and since Kurbo is an offshoot of WW, you’d think the app would be up to speed, but the WW app is light years ahead. The concept of this app is wonderful. The app layout and features is severely lacking and until it is updated, I will have to find something else to help me track my daughter’s nutrition.
