Way better than my fitness pal, better more precise inventory of food, better graphics, more detailed info, yet more simply displayed and easier to read. I’ve used it for 2 years and love this app, both free and gold versions

Not functional, bad UI, terrible support
Txambergoetxea
I tried to subscribe and always get “payment declined “ which is not true as I have other subscriptions and purchases with the same card (same day) and my bank always sends me an SMS when a payment is declined. Anyway, I contacted support and received an empty email as a response. EMPTY. The free version doesn’t even allow you to log in time on your meals. It’s ridiculous.
