How to log sleep manually when you do not wear a watch
Free printable blood pressure log (PDF)
How to log sleep manually when you do not wear a watchis a phone habit, not a hardware problem. You wake up, you estimate or remember the hours, and you write them down before the morning blurs. Blood Snap's Sleep log is built for that case. The screen even says it is for days without a sleep tracker.
Blood Snap is a wellness diary. It will not sense that you are asleep, and it will not invent a duration because your phone sat on a nightstand. If you do not wear a watch and you do not use another sleep app, the manual row is the whole record. That is a valid diary. It is not a medical device and not a sleep study.
You do not need a watch to keep the diary
Watches estimate sleep from movement and heart rate. Phones sometimes do the same if an app is allowed to run overnight. Plenty of people use neither. They still want a number next to a morning blood pressure check: short night or long night, written the same way all month.
Manual logging in Blood Snap does not ask for Apple Health or Health Connect. You can leave those switches off. Steps and resting heart rate are separate cards, described in steps, sleep, and resting heart rate, and you can ignore them if you only want typed sleep.
Log last night on your phone
Use this path most mornings:
- Open More Health → Sleep log.
- Stay on Log and tap Add sleep.
- Answer Which morning did you wake up? Today is the usual choice. Pick an earlier date if you are filling a gap. The earliest date is one year back.
- On Time asleep, set hours and minutes. The fields start at 7 and 0. Change them.
- Save. You should see the weekday and date, then a line such as 6h 15m asleep.
- Turn on Show sleep on dashboard if you want that duration on Home next to blood pressure.
Faster, for this morning only: More Health → +→ sleep. The sheet asks how long you slept last night, in hours and minutes, and saves it on today's date. It also turns the Home sleep switch on. It does not let you pick a different morning. For a missed day, use Add sleep.
Minutes have to be from 0 to 59. Hours have to be from 0 to 24. The total has to be at least one minute and at most 24 hours. If save does nothing, the number is outside that range.
A consistent way to estimate
Without a watch you are estimating. Pick one method and keep it:
- Lights-out time you remember, minus the time you woke, minus a rough allowance if you know you were awake for a stretch.
- Or a single figure you would tell a clinician: "about six hours." Enter 6 hours and 0 minutes, not a false-precise 6 hours and 7 minutes.
Write the estimate the same morning, not three days later from memory of a memory. The diary cannot fix a guess. It can show you the guesses in a row. On Analytics, average, longest (Best), and shortest (Worst) are calculated from those durations. They are not a sleep-quality score. A 9 hour night is "best" only because it is longer.
If you also log water or a cuff reading in the same sitting, do those as their own steps. Water is millilitres in the water log. Blood pressure follows the home blood pressure diary. A reminder to open the app can be a custom health reminder at your usual wake time. The reminder does not create the sleep row.
If you connect a phone or a watch later
You can start manual and add a tracker months later. Switch sleep on in More Health and allow the read on iPhone (Apple Health) or Android (Health Connect). Blood Snap then shows tracker asleep minutes for that day on Home and History. When both exist, the tracker wins on those screens. The typed nights remain in the Sleep log list, and Sleep log analytics and Pro export still use manual entries only.
Tracker values are read when you view them. They are not stored as Sleep log rows and they are not sent away for interpretation. If you use Blood Snap Pro and turn on sleep sync, a night you add from the Sleep log can be written out to Apple Health or Health Connect. The free manual diary does not require that.
Review a week of manual nights
Open Analytics and choose 3, 7, or 30 days. You will see how many entries you saved, the average duration, the longest, the shortest, the total time, and a chart of hours asleep per night. Days you skipped are empty on the chart. That gap is information: you did not log, which is different from a logged short night.
Bring a Pro export if someone asks for a file. Otherwise the phone is enough. Pair the week with weight only if you already weigh in; that record is the weight and blood pressure log, not a field on the sleep entry.
Limits of a no-watch sleep log
- It records what you type, including a confident wrong guess.
- It does not know when you woke at night unless you shorten the duration yourself.
- It does not diagnose a sleep disorder or tell you whether a reading is safe.
- It does not require a wearable, and it does not become a wearable if you leave Health access off.
Log sleep manually in Blood Snap when you do not wear a watch. Choose the morning, enter hours and minutes, and review 3, 7, or 30 days for free. A tracker is optional later. Not a sleep study and not a medical device.
