Why is it telling me to input how much carbs I want to eat?

What kind of calculator tells you to enter the results instead if it calculating the carb intake I should be aiming for based on my stated goals?

New Keto Person

I’m still trying to understand the Keto diet. I really appreciate the Free no strings Calculator. I love that it offers you different calorie options and lots of information that I need. Keep up the great work.

I hope they will keep this Calculator updated with new features as it hasn’t seen an update in 2 years.

I thought this app would TRACK the food … but Nope! It forces you to download their other app that you have to PAY to use it! So it’s false advertisement as β€œFree”.
