Read the change, then inspect the signal.

A daily number is only useful when you can see what moved it. daygauge keeps the comparison close to the underlying sleep, movement and habit readings.

The daily read

The useful parts stay close to the signal.

Life Index

One daily score from 1 to 1000, built from your sleep, movement and recovery compared with your own recent average.

Weekly Review

What changed this week, what held and one thing to try next. Your first review is free.

Private by default

Apple Health readings and precise place points stay on your iPhone. Continuous routes are not saved.

Core loop

Personal patterns, without pretending they are proof.

daygauge compares signals in your own history. It can show that two things moved together repeatedly, but it does not turn an association into a diagnosis or a causal claim.

Your data stays close to you. Health readings, places and notes are processed and stored on your iPhone. Health readings are never uploaded.
Quests

Test one change against your own baseline.

Pick one small change, such as a consistent bedtime or alcohol-free weekdays, then compare your next readings with your usual. Your first Quest is free; ongoing Quests are part of Pro.

What changes
You make one change for a few comparable days. Keeping it to one change makes the result easier to read.
What moves
Sleep, movement, resting heart rate and HRV are compared with your usual. You see what moved while the Quest ran and what else changed at the same time.
What it does not claim
No diagnosis, treatment or proof of cause. A Quest shows what happened in your own data, with the days behind it.
