Alba | Health and Sleep Care

Wear your Apple Watch to sleep and Alba records it for you. Rate how you feel with one tap from a notification. Open the app only when you want to look back.

Know yourself, by first light.

Alba quietly records your sleep and how you feel, then turns it into a picture of your own "usual." Wear your Apple Watch to sleep and your sleep stages and vitals are logged automatically in the background. Rate your condition with a single tap from the morning and evening notifications. You only open the app when you feel like looking back.

THE RECORD CONTINUES, EVEN UNOPENED • Sleep, recorded automatically. Sleep stages (deep, REM, core) and total sleep time are logged in the background. • Vitals while you sleep: heart rate, heart rate variability, blood oxygen, and respiratory rate. • Daytime activity, hands-free. Steps, heart rate, and resting heart rate accumulate on their own. • Condition in one tap. Long-press the morning or evening notification and choose from five buttons.

SEE YOUR NIGHT, AS IT HAPPENED • Last night's sleep at a glance: deep sleep in purple, REM in yellow, core in blue. • A sleep timeline overlays heart rate and respiratory rate onto the night's stage transitions, so you can follow the flow of your sleep just as it happened.

LOOK BACK ON YOUR RHYTHM • Your sleep rhythm on a calendar, each day colored by how long you slept. • Morning and evening condition scores line up in two colors. • Go deeper into any day: your condition score and comment alongside that day's steps, heart rate, HRV, blood oxygen, and respiratory rate.

ON YOUR WRIST The Alba app for Apple Watch records your sleep and vitals, and lets you log your condition without reaching for your iPhone.

ALBA PRO Alba Pro unlocks: • Sleep statistics by period: average sleep time, stage breakdown, average bedtime and wake time • Comparison with your personal baseline, so you can see whether each day is higher, lower, or about the same as usual • Weekday trends and visualized correlation with your condition score • CSV export of your sleep, vitals, and condition data • Automatic export to Google Sheets

It's your data. Export it and feed it to the AI of your choice for advice that's grounded in your own records.

WHAT YOU NEED An Apple Watch, or another wearable that syncs health data to Apple Health on your iPhone, is required to record sleep and vitals automatically. Support for more smartwatches is planned.
