Ratings and reviews

This is the best calorie counting app I’ve found so far. I downloaded five different apps to see which one suits me best, and this one clearly stands out. Accuracy is the most important factor for me, and this app lets me log the exact weight of what I eat. Other apps require choosing preset portions, which forces me to do extra math. I also haven’t experienced the excessive ads that some users have mentioned, therefore I assumed they fixed the issue. Highly recommended.

The first week is really misleading--ads get a LOT worse after. I like the big plus button at the bottom center and that it syncs with Samsung Health. it's a little frustrating that I can't fix incorrect nutrition myself, but they seem to be responsive when changes are requested so 🤷 I don't love how items appear in the search but I'm dealing with it.

Just got it yesterday. I love the UI - it feels more approachable than other apps, as someone who wants to keep track of her goals with more focus on nutrition and well-being and not have overwhelming calorie tracking; this strikes a good balance. Trying it for free and hoping to love it so much I pay for the premium version. Right now the home screen widget doesn't automatically refresh for a new day so I have to delete and add the widget to refresh the net cals for the day!
