The question

Quick answer

daygauge does not log food or meals. You can add a custom habit in Quick Log, such as an early dinner, and see it next to your sleep, movement and heart readings.

Illustrative example

What this can look like in the app.

Early dinner logged: you fell asleep 28 minutes earlier than on your late-dinner days.

Example
Confidence

A pattern is only called proven after it repeats on your own paired days. Missing readings lower confidence.

Next move

Try one small change, log it in Quick Log, then compare your next readings.

Example 1

Late dinner logged: the nights after coincided with shorter sleep and a higher resting heart rate.

Example 2

Evening walk logged: on those days your resting heart rate the next morning was close to your average.
