Flexible Dieting Needs Flexible Tools
A flexible dieting app shouldn't impose food categories or restrictions. The workflow is: see macro targets, log any food, hit targets. Apps that gate macros behind subscriptions or impose food categorisation work against the framework.
How We Evaluated
- Per-macro targets free
