Health Connect

Available on Android only.

Your watch, ring or fitness app already records when you sleep and when you work out. aTimeLogger can read those records from Health Connect and put them next to your own log:

See sleep stages, heart rate and workout details right on the activities you log
Add a night or a workout you forgot to log with one tap
Fix the start and finish of a logged activity to the times your watch recorded
View sleep and workout statistics: sleep score, sleep schedule, heart rate zones, training load

Health Connect is a premium feature.

Info

The app only reads from Health Connect. It never writes or changes your health data.

Requirements

Android 9 or newer. On Android 9–13, install the Health Connect app from Google Play — the app shows an Install Health Connect button if it's missing. On Android 14 and newer, Health Connect is part of the system
An app that saves sleep or workouts to Health Connect, for example the app of your watch or ring
Premium. Without it you can open the Health Connect screens and connect, but sleep and workouts are not imported or shown

Info

Health Connect is not available in the Huawei version of the app.

Opening Health Connect

Go to More → Health Connect. The screen shows:

Sleep — the activity type your sleep is logged as. Opens the sleep statistics
Workouts — how many workout types are mapped. Opens the workout statistics
To review — the number of sleep and workout sessions that don't match your log yet. See To review
Settings — connection, sleep and workout settings
Heart rate zones — see Heart rate zones

While sleep or workouts are turned off, their rows show Not imported and open the settings instead.

Connecting

Open More → Health Connect → Settings
Tap Connect and allow access in Health Connect

The app asks to read:

Data	Required	Used for
Sleep	Yes	Nights, sleep stages, sleep score
Exercise	Yes	Workouts
Heart rate	Yes	Heart rate charts, zones, training load
Distance	Yes	Distance, pace and speed of workouts
Active calories	Yes	Active energy of workouts
Resting heart rate	No	Recovery part of the sleep score, heart rate reserve zones
Past data	No	Data older than 30 days

The settings screen shows the connection status:

Connected — everything is shared
Some data is not shared. Connect again, or allow it in Health Connect. — some data types are not allowed. Data you didn't allow is simply missing; there is no error
Allow past data — Health Connect shares only data from 30 days before you first connected. Allow past data to see sleep and workouts on older activities

Info

If you deny access twice, Android doesn't ask again. Tap Open Health Connect and allow access there.

To disconnect, remove the access in the Health Connect app. Turning Sleep or Workouts off in the settings stops the import but keeps your type mapping.

Sleep

In Settings, turn on Sleep from Health Connect and choose Log sleep as — the activity type for your sleep. If you have an active type named "Sleep", it's selected for you. Until a type is set, the row shows Not set and nothing is imported.

Activities of this type show the night Health Connect recorded at the same time.

Workouts

In Settings, turn on Workouts from Health Connect. The list shows the workout types recorded in the last 90 days, most frequent first. Each one starts as Not used.

Tap a workout type to map it:

Log as — the activity type for this kind of workout
Tags — tags added to the activity. Useful if you track every sport under one type, for example Exercise with the tags "running" and "cycling". See Tags
Stop using this type — remove the mapping

Tap Add workout type… to map a type that isn't in the list yet. The catalogue has a search field.

A workout kind logged as Exercise with the tag running

Info

Only mapped workout types are used. Several workout types can map to one activity type.

Health on your activities

Open an activity of a mapped type (Edit activity screen). Under the intervals, the Health section lists the sleep or workout Health Connect recorded at the same time, for example Health: 23:10 – 07:02. Tap it to open the details.

This works for activities you logged yourself too: the app finds the session by time.

Health section on the Edit activity screen

Workout details

Heart rate chart
Heart rate zones — the time in each zone, based on your max heart rate. Tap Zone settings… to change the zones
Summary — Duration, Distance, Average pace, Average speed, Active energy, Average heart rate, Max heart rate (only what was recorded)
Source — the app that recorded the workout, with Open Health Connect

Sleep details

Sleep stages chart (Awake, REM, Core, Deep) and the heart rate during the night
Breakdown of the stages
Sleep score — see Sleep score
Night stats — Time asleep, Time in bed, Efficiency (needs sleep stages), Awakenings
Sources — the apps that recorded the night

Use Health times

If the times of your activity and of the Health session differ, the details show both — Health: … and Your log: …. Tap Use Health times to copy Health's times into the activity, then save the activity. Available for activities with one interval.

Import suggestions

When you open the app, it checks Health Connect for new sessions (at most once every 15 minutes) and shows a card at the top of the Activities tab:

Card	Buttons	What happens
You slept 23:10 – 07:02 / Workout 18:00 – 18:48	Add / Dismiss	Add creates a stopped activity of the mapped type, with the mapped tags, at Health's times
Sleep is still running. Health shows 23:10 – 07:02	Stop / Continue	Stop stops your running activity
Health shows 23:10 – 07:02, your log has 23:30 – 07:00	Update time / Keep mine	Update time changes the activity's interval to Health's times

Workout cards also show the details, for example 48m · Running · 8.24 km · 512 kcal.

How the cards work:

The app waits a little after a session ends before suggesting it: 20 minutes for sleep, 10 minutes for workouts
Only nights of 3 hours or more get a card. Naps don't
Workouts shorter than 1 minute are ignored
If two apps recorded the same session, it's shown once
Times that differ by less than 1 minute count as the same. Update time is offered only within 24 hours after the session, when the times differ by more than 5 minutes and the activity has one interval
Dismiss, Keep mine and Continue are remembered — the same card doesn't come back

Info

The app checks Health Connect only while it's open. There is no import in the background.

To review

More → Health Connect → To review lists everything in a week or month that doesn't match your log, including older sessions that never got a card:

Not in your log — sessions without an activity. Add or Dismiss each one, or Add all
Times differ from Health — activities whose times differ. Update time or Keep mine for each one, or update them all at once. A line above shows the average difference, for example Starts 12m later in Health

Each row shows the Logged and Health times. Tap a row to open its details. When everything matches, the screen shows Nothing to review.

Sleep statistics

More → Health Connect → Sleep. Switch between week and month and page with the arrows:

Bars — each night by sleep stage, with the average line. Nights that are not in your log are faint. Tap a day, then tap again to open the night
Sleep schedule — when you went to bed and woke up
Summary — average Time asleep, Sleep score, Bedtime, Wake up, Consistency (±minutes), Deep and REM share, Nights (X of Y logged)

Naps are shown in the bars but not counted in the summary. Use Refresh from Health Connect in the menu to read the data again.

Sleep score

The app's own estimate of a night, from 0 to 100:

Part	Weight	Full score	Zero
Duration (time asleep)	40	7h 30m – 9h 30m	4h or less
Efficiency (asleep ÷ in bed)	20	90%	65%
Deep & REM (share of the night)	20	40%	15%
Recovery (lowest heart rate of the night vs. your average resting heart rate over the last 30 days)	20	At or below it	15 bpm above it

Above 9h 30m, duration loses 10% per extra hour. A part without data — no stages, or no resting heart rate — is left out, and the other parts count for more.

Rating: 85–100 Excellent, 70–84 Good, 50–69 Fair, below 50 Poor.

Workout statistics

More → Health Connect → Workouts. Shows every workout recorded in Health Connect, mapped or not. Use the chips at the top to filter by workout type.
