Ratings and reviews

I love the app in free mode, great for recording food, and it connects to polar for my exercise calories used. Adverts kick in as soon as you try to add a second item to a meal, inconvenient but premium membership is £41.99 a year or £5.60 a month, far too expensive to remove ads and add photo logging and repeat items. If it was £10 a year, I'd consider it, as there are other apps available with way more functionality at that price.

The app itself is good and fairly easy to use, however the full screen adverts that come in like a jump-scare and play sound over what I am already playing are awful and a terrible user experience. I simply don't want all the "premium" features for any subscription fee, but if there was to be an option for a one-off payment for the basic service (what we currently get for free) without any ads, I could be convinced. Otherwise it will be an immediate uninstall once I get what I need from it.

I got the app a few days ago and quickly started using it on all my meals. Great app, very eye opening on the food I eat and especially on quantities/calories. Love the details on macros/micros and the various functionalities. However since 2 days I'm seeing ads a lot more. It's the worst type of ads which takes the whole screen and blocks your phone all together. I'm surprised that this format for ads is even legal. It is a big turn off sadly.
