Very simple easy to get started no fuss, straightforward

Nice & simple, but of limited use

In a very short quiz, the app asks you perhaps seven questions, and then gives you targets for daily carbs / fat / protein. That’s it.

It does not help you calculate what you’ve eaten, nor is there a way to adjust how quickly you want to lose weight, if that’s your goal. There’s no food database, no daily inputs, no stats. You might use this app a few times a year on a weight loss / gain journey. You’d still need to use some other app or method to find out what your daily totals actually were. A companion app to this one would be lovely!

Also, I found it funny that an app called “Fiber” doesn’t help you track or set a goal for, you know…fiber.

This app does nothing

Basically this is a calorie calculator can add anything to the app food calories etc…

This app doesn’t do anything?

It gave me my recommended macro breakdown. That’s it. Where do people track daily intake? Other than settings there is no interactivity with this app.
Side note; this app gave me a waaaay low calorie recommendation. It’s way off 😳

Am I missing something?

I thought this was going to be a calorie tracking app. After the quiz, a chart came up with a total calorie intake suggestion but that was all. There was not a place to log food and keep track of calories, fat, carbs, etc.
