Why hydration tracking is worth the (tiny) effort
Hydration is the lowest-effort, lowest-leverage entry on this site — which is exactly why a frictionless app makes sense. The Mayo Clinic’s general guidance is straightforward: drink enough that you rarely feel thirsty and your urine is pale yellow. A tracking app helps mostly by reminding you, not by measuring you.
If hydration is the only thing you’re tracking, you’re probably under-tracking. Pair it with a nutrition app for a complete picture.
