Very good, good mix os minimalist and working functionality. I would prefer some more possibility of custom dashboard like features. Thanks.
Developer Response
Thanks for the generous review, and it's great to hear that you're finding the app minimalist yet very functional. We hear your suggestion and we are always looking for ways to provide more insights for our users. Have you tried playing around with custom charts? If you have different devices linked, you can make charts that reflect your goals. For example, if I wanted to be more proactive about getting more quality sleep, I could track my magnesium against my Sleep Score brought in by a wearable device and then have that easily monitored in the app. We appreciate your support!
Precise data
Alexdev0
This app is incredibly precise and absolutely worth using. The data is quite accurate, i normally don't use calorie-tracking apps, I usually use a research-based program, but that one only exists on desktop. So I decided to try looking for an app again, even though i wasn't very hopeful, and I had heard that this one was supposed to be fairly research based as well.I tested it for one day and compared it to the program I normally use, and I was positively surprised by how accurate it was. Actually, it was almost more accurate than the program I use. Now it has become way easier to log everything on my phone instead of on a computer, which is amazing, and it's definitely something I can trust.Definetly recommend this app for anyone who's serious about nutrition tracking, or bodybuilding .

Incredible app!
Julian Sagen
This app is absolutely amazing. It got a huge database with all the nutrients in pretty much any food item, even here in Norway. If a food item isn’t in the database yet it’s really easy to take a photo and add it for all users of the app. The customer support is outstanding even when you are a free user and they will quickly validate any food item you add so there is no huge errors in their database.This app is absolutely life changing.
