Travel breaks routines in ways your wearable rarely explains.
daygauge shows your sleep, movement and recovery readings next to your days away, so you can see how a trip changed your pattern.
Start with what your own data can show.
Many people want practical timing help before and after travel.
daygauge shows the whole day in your Timeline, beside readings from Apple Health such as steps, sleep and time in daylight. You can log caffeine and alcohol in Quick Log.
daygauge shows your Timeline places and journeys beside your sleep, movement, time in daylight, HRV and resting heart rate after a trip. Comparing travel with your health readings is part of Pro.
What this guide covers.
How the app handles this.
What this can look like in the app.
Arrival day: sleep was 2h 10m shorter than your average and started much later than your usual window.
ExampleConfidence rises when the same pattern repeats against your own baseline and drops when key signals are missing.
Try one small change, log it, then see whether the pattern repeats over the next week.
Example 1
Daylight: time in daylight on arrival day was well below your average.
Example 2
Recovery: resting heart rate 5 bpm above your average after a late flight, an alcohol log and short sleep.
