I’m currently working on fixing my diet and fitness. One major part of it is maintaining a ratio between fat, protein, and carbs.

Currently I’m trying to use the Apple health task to this. However, they work like an average number tracker. The problem with this is if the number of calories I intake changes, so should the number of my macros.

So my idea was to make a new Apple Health tracker for each macro, based on percent instead of number.

For example, 1g of fat is worth 9cal. So:
Apple Health sends 50g of fat and 900cal.
Strides runs it through (fat x 9/cal) = (50 x 9/900) = .5
Task shows 50%

The same would happen with protein and carbs tasks, except that they are worth 4cal each instead of 9.

As for the user input, they can set their goal as percentage. Ideally they would be able to set it as a percentage range, but I would be content either way.

Set percentage:
Fat ratio goal = 30%

Set percentage range:
Fat ratio goal = 25%-35%

Thank you for your time and I hope you approve this idea.
