Sleep log app free: keep a manual sleep diary
Free printable blood pressure log (PDF)
A sleep log app freeof charge should let you write down the night in plain numbers: which morning you woke, and how long you were asleep. Blood Snap's Sleep log is a manual sleep diary inside More Health. You do not need a subscription to add nights, and there is no limit on how many nights you keep.
Blood Snap is a personal wellness diary. It is not a medical device, not a sleep lab, and not a watch. It does not detect sleep while you are in bed. You enter the duration after you wake, or you let a tracker you already use show its duration on Home. The sections below cover the manual diary.
A manual sleep diary, not a score
Open More Health → Sleep log. The screen says it is for days without a sleep tracker, and that if your phone or watch already recorded the night, that value is what gets shown. The log itself is still the place you type a night by hand.
Each saved row is a date and a duration, such as 6h 40m asleep. There is no sleep stage, no snoring flag, and no 0–100 score. On Analytics, the labels Best and Worst mean the longest and shortest durations in the period. They are not a judgment that one night was healthy.
How to add a night
- Open Sleep log on the Log tab.
- Tap Add sleep.
- Choose the morning you woke. The picker asks "Which morning did you wake up?" and allows dates from the past year through today.
- Enter Time asleep as hours and minutes. Minutes must be 0–59. The total must be more than zero and no more than 24 hours.
- Save. The row appears with the date and the duration. Delete it if the number is wrong and add it again.
The hours field opens on 7 and minutes on 0 so you have a starting point to edit. Replace both with the night you actually had. Saving the prefilled 7 hours when you slept less will only clutter the chart.
The +button on More Health can also log sleep: hours and minutes for last night, saved on today's date. Use Add sleep on the Sleep log when the night belongs to an earlier morning.
Log and Analytics
Log lists the manual nights and includes Show sleep on dashboard. With that switch on, Home can show sleep for the day. Adding a night from the More Health + sheet turns the switch on if it was off.
Analytics covers 3, 7, or 30 days of manual entries. When the period has rows, Sleep stats shows:
- Entries — how many manual nights fall in the window.
- Average — average duration.
- Best — longest duration.
- Worst — shortest duration.
A line under the stats gives the total time across those nights. The chart is Sleep over time, in hours asleep per night. Empty windows ask you to log sleep before stats appear. This chart is the manual diary. It does not plot a watch's sleep stages.
When a tracker is also connected
You can switch on a free read of sleep from Apple Health on iPhone or Health Connecton Android. Blood Snap asks for read access and shows the tracker's asleep minutes for the night that ends on the day you are viewing. Overlapping records from a phone and a watch are merged so the same night is not counted twice. Those reads are not copied into Blood Snap storage and are not sent off the device for analysis.
If a tracker value and a manual entry both exist for the same day, the tracker value is shown on Home and in History. Your typed row stays in the Sleep log until you delete it. That is why the log tells you it is for days without a tracker. The full picture of steps, sleep, and resting heart rate on the dashboard is in track steps, sleep, and resting heart rate with blood pressure.
Writing the other way — sending a manual night out to Apple Health or Health Connect — is Blood Snap Pro, under Settings → Health & data, and only for sleep sync you turn on. The free read on Home does not require Pro.
Free logging and Pro export
Unlimited manual entries, the Home switch, and 3/7/30 analytics are free. Export from the Analytics period is Pro. The file is titled as a sleep log of manual entries only, with the date, the duration, and a notes column. The add flow asks for the morning and the duration; it does not ask you to type a note on the night.
The same diary holds the rest of the morning. A cuff reading still follows the home blood pressure log. A glass of water still goes through the water log, and a drink reminder is still a custom health reminder, not an automatic sleep or water entry. Weight on the same days belongs in the weight and blood pressure log.
What this sleep log cannot do
- It cannot tell you when you fell asleep unless you estimate the duration yourself.
- It does not record REM, deep sleep, oxygen, or snoring.
- It does not diagnose insomnia, apnea, or a safe amount of sleep for you.
- It does not change your blood pressure entries based on a short night.
