A waste of time

Not only is 90% of the features in this app behind a paywall, but if you have slow metabolism, I highly doubt you will lose any weight. After following the rules and eating limits for a week, not only did I not lose any weight, but I gained FOUR POUNDS. I used this app for a mere week, and I gained 4 pounds. Please do not waste your time on this app.

TERRIBLE AI

I used to love this app. Recommended it to everyone. Used it for YEARS but it has become TERRIBLE. The AI is just awful.

This app will is pretty good

The apps is alright it’s just hard to track food by there real name. I am Mexican and the foods I eat have specific names. The app doesn’t have those foods. I have had to put the foods individually into the app. Everything else is ok.

Great tracking app!!

Easy to use!!

User Interface sucks..

I used Lifesum in 2018. It helped me go down from 61-56. Result wise, amazing. The app though? Oof… I signed up again even though I found it really lacking back then, hoping for some change but not much has changed and if I were to draw a flowchart for how the app works, it’s so so confusing which leads to a lot of time being wasted and me wanting to almost give up using the app. I’ve decided not to renew again which is a bummer because result wise, it gives you the result.

I was a UX/UI student when I first got the app in 2018 and I redesigned many aspects of it for a class project and I think that made a lot more sense than this does. Please change the UI.. it’s so frustrating to work with
