Start with the signal your own data can support.

People search for a life score app because they want one calm number for how their day is going.

The useful version answers four questions: what moved it, what data was used, how confident is the read, and what should I try next?

Quick answer

daygauge keeps the Life Index inspectable: observed value, baseline value, source, confidence and score impact.

How daygauge would use this

From research context to product evidence.

Signal

daygauge keeps the Life Index inspectable: observed value, baseline value, source, confidence and score impact.The score is a navigation layer for sleep timing, movement spread, recovery proxy, consistency, balance and life-log context.

Confidence

Missing or sensitive data lowers confidence instead of creating false certainty.If the signal is not measured, explicitly imported or user-approved, daygauge should say so in the evidence.

Weekly review

Pro keeps the weekly baseline review: what changed, what moved with it, and whether the pattern repeated.This is where daygauge has to beat a generic wearable dashboard: clearer explanation, baselines and boundaries.

Example evidence

What a user should expect to see in the app.

Movement spread: 11,400 steps across 5 active windows, +49 index impact, high confidence.

Weekly review preview

Data used

Sleep timing, movement spread, recovery proxy and habit context compared with your usual weekday baseline.

Confidence

Confidence rises when the same pattern repeats against your own baseline and drops when key signals are missing.

Next move

daygauge would suggest one small experiment, then watch whether the evidence repeats over the next week.

Boundary

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

Evidence 1

Movement spread: 11,400 steps across 5 active windows, +49 index impact, high confidence.

Evidence 2

Sleep timing: midpoint 34 minutes earlier than your Tuesday baseline, +19 index impact.

Evidence 3

Recovery proxy: resting HR +3 bpm versus baseline, -15 index impact, medium confidence.
