Ratings and reviews

I thought it'd be a good app judging by the score but I guess standards have just got pretty low for apps. The basic functionality is fine, presentation could use a little work, but all the interesting features are of course locked behind a subscription. Problem is they charge a stupid amount for it and it's subscription only so it'd be a never ending fire of money. when did twenty dollars monthly become the default? this does not offer that kind of value, that's closer to a one time cost.

The only free calorie calculator app to let you scan barcodes. Smaller food label sample pool but you can make do. I adjusted my rating because what was one simple quick ad is now multiple intrusive time consuming annoyances. at first you could just click the X and get rid of it. Now you have to wait for the X to show up. Find the X. Click multiple x's for one ad. Measuring my food has become so much more of a chore because of this "small" change. If they don't change it back soon. I'm leaving

Full screen ads in the free version does not make me want to keep using it long enough to see if its better than MFP. Edit; yeah nah two full screen ads before I can even put in one meal, and I already couldn't find one food (Bakers Delight Vienna loaf). The annual subscription seems good value, but I want to actually try the app without getting endless temu ads. As someone who's already established using MFP, there's no reason for me to change to this app at the moment.
