My Fitness Pal too, you can tap a macro pie chart at any point in the day to see how ratios stand. But.... remember no app can tell how much body fat you are burning, so not to worry much about those "ratios", good explanation : https://blog.virtahealth.com/top-keto-mistakes/.
You can custom the goals on the free version of MFP to something like 5-20-75% but the apps are most helpful for counting the carbs and protein in grams to be sure those are below the limits you want to keep.
