Habit analytics

A habit tracker can show what your routines do to your readings.

daygauge lets you log a habit in a tap, then shows it next to your sleep, movement and recovery from Apple Health.

The question

Start with what your own data can show.

Nobody wants to log every healthy behaviour forever.

daygauge keeps logging small. Places and movement come from your iPhone, Apple Health supplies your sleep and recovery, and you log the one habit you want to test. Then you compare your readings.

Quick answer

Quick Log has habits such as late caffeine, no alcohol, no vape and a post-meal walk. You can also add your own custom habit.

In daygauge

How the app handles this.

Signal
Habits are free to log. daygauge avoids moral language. It asks whether a logged change coincided with a change in your readings, not whether you were good or bad.
Confidence
Missing readings lower confidence instead of creating false certainty.When a reading is not available, daygauge says so rather than filling the gap.
Weekly Review
Weekly Review shows what changed, what held and what to try next.Your first Weekly Review is free. Later reviews are part of Pro.
Illustrative example

What this can look like in the app.

Late caffeine: on days you logged it, your sleep started 26 minutes later than your usual.

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

Post-meal walk: you logged a walk after lunch on 4 days. Your steps were above your average on all four.

Example 2

No alcohol: on your last five alcohol-free days, your resting heart rate was lower than on your other days.

Research

Further reading.

These studies describe groups of people. They help explain the topic, but they cannot tell you what will happen to you.

Research context only. daygauge does not diagnose, treat, prevent or predict disease risk. Personal medical concerns belong with a qualified clinician.

Limits

What daygauge does not do.

  • It does not diagnose, treat or prevent disease, or predict your risk of it.
  • It does not claim one habit caused a result. It shows the pattern, how confident it is and what else changed.
