Know yourself, by first light.
Your smartwatch records sleep, heart rate, SpO2, and respiratory rate while you sleep. Without ever opening the app, each day's condition quietly builds up.
The values recorded are measurements from your smartwatch (Apple Watch is supported today; other smartwatches are planned).
Alba is not intended for medical use.
The record continues, even unopened.
You only open the app when you feel like looking back. The recording itself takes no effort.
Sleep, recorded automatically
Just wear your smartwatch to sleep. Your sleep stages and vitals during sleep are logged automatically in the background, without opening the app.
Daytime activity, hands-free too
Daytime data like steps and heart rate accumulates on its own. By the time you notice, it's already there to look back on.
Condition, one tap from a notification
Record your daily condition score straight from the notification you receive. No need to find and open the app.
Last night's sleep, at a glance.
Just wear your smartwatch to sleep, and Alba records your sleep stages (deep, REM, and core) and total sleep time. 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. (Depending on what data is available, some values may be filled in as estimates.)
Sleep statistics, by period.
Choose a period — a week, a month — and review your sleep stage breakdown, average bedtime and wake time, and average heart rate, SpO2, respiratory rate, and HRV during sleep, all in one place. From your daily records, the patterns in your own sleep come into view.
Today's condition, in a simple score.
Leave a condition score and a short comment in the morning and evening. Your daily records line up on the calendar in two colors for morning and evening, so you can look back on the ebb and flow of how you felt. It's a gentle, sustainable way to record your ups and downs.
Your sleep rhythm, on a calendar.
Switch to the calendar and each day's sleep time appears in a color that reflects its length. Your average sleep time and average bedtime and wake time over the last 7 days are shown alongside it. A week of late nights or a week of good rest — either is clear at a glance.
Go deeper into a day's condition.
For any day you choose, view its condition score and comment alongside that day's steps, heart rate, HRV, SpO2, and respiratory rate. Each value shows its difference from your usual baseline as + or −. Comparing how you felt with what was actually recorded deepens your understanding of your own condition.
Grounded in your own "usual."
From your entire history, Alba continuously calculates a sense of your usual state — your baseline. From sleep time to heart rate, HRV, and daytime steps, it shows whether each day's values are higher, lower, or about the same as usual, giving you a cue to notice changes in your condition.
Your data is yours. Take it with you.
The records that build up in Alba are never locked in. Take them to the tools you already use, whenever you like.
Google Sheets integration
Alba writes to your own spreadsheet every day, across three tabs — sleep, vitals, and condition. Your sheet grows even when you don't open the app. Summaries and charts are yours to build, with all the freedom of a spreadsheet.
CSV export
Export your sleep, condition, and vitals data to CSV for any period, anytime — whether you want to keep a copy for yourself or analyze it in another tool.
What you do with the data you take out is entirely up to you. One nice option: hand it to the AI you use (ChatGPT, Claude, Gemini, and others) and talk through your own sleep and condition.
Your health data is yours.
Alba does not use your health data for advertising, and uses no third-party SDKs for tracking. Data obtained from HealthKit is never shared with third parties without your consent.
