Health Connect blood pressure app: keep a diary on Android
Free printable blood pressure log (PDF)
A Health Connect blood pressure appon Android has two jobs that are easy to mix up. Health Connect is the phone's shared store for health data. A diary is the record you check, chart, and bring to a clinic. Blood Snap is the diary. It can read a few metrics from Health Connect for free, and Blood Snap Pro can sync selected logs both ways after you turn that on.
On Google Play the listing title is Blood Pressure & Glucose Chart. Inside the app the name is Blood Snap. It is a personal wellness diary, not a cuff and not a medical device.
What stays in the diary
You still measure with your home monitor. Then you type, speak, or snap the screen and confirm systolic, diastolic, and pulse before the row is saved. Notes, History, and Insights belong to that confirmed list. Insights uses 3-day, 7-day, and 30-day windows. PDF and CSV export is Blood Snap Pro.
Health Connect does not add the seated routine, the note, or the visit file. Those stay in the diary. The same idea on iPhone is covered in Apple Health versus a dedicated diary.
Free reads from Health Connect
In More Healthyou can switch on steps, sleep, and resting heart rate. The first time, Android asks you to allow Health Connect read access. Blood Snap then shows those values when you open Home, History, or Insights. They are read for display. They are not copied into the diary's saved readings and they are not sent off the phone for an AI parse.
- Steps. The Health Connect total is shown when it exists. Otherwise a manual steps entry from More Health is shown.
- Sleep. Asleep time can be read from Health Connect. You can also type a night in More Health.
- Resting heart rate. Shown as a metric beside the diary when the toggle is on. You do not type it as a blood pressure row.
See steps, sleep, and resting heart rate next to blood pressure for how those cards relate to a cuff log.
Pro two-way sync
Two-way sync is Blood Snap Pro, and it stays off until you opt in. Open Settings → Health & data, turn on Sync with Health Apps, and grant Health Connect. You can enable each type on its own:
- Blood pressure, including pulse, so a confirmed diary row can be written to Health Connect and matching Health Connect records can be pulled into the diary.
- Blood glucose, the same way.
- Weight you logged in More Health.
- Sleep, including a manual sleep entry when sleep sync is on.
Pick one place as the list you trust. If you log in Blood Snap and also type the same reading into another app that writes to Health Connect, you can end up with two rows. Confirm the digits once, let sync run, and avoid a second manual copy.
A practical Android setup
- Install Blood Snap and log blood pressure the way you already measure it at home.
- Turn on steps, sleep, or resting heart rate in More Health if you want those reads.
- If you want records to move both ways, subscribe to Pro and enable only the types you use.
- Check Health Connect permissions any time in Android settings. Turning sync off stops future sharing.
- Export the diary before a visit. A Health Connect dump is not a substitute for the rows you confirmed.
What Health Connect plus a diary cannot do
- Neither product takes a blood pressure reading.
- Neither diagnoses hypertension or labels a reading as normal or high.
- Neither replaces your clinic chart or an emergency service.
- Sync does not send those readings to an AI service. Parsing a snap or a voice entry is a separate, optional consent.
Keep the Android diary, and use Health Connect when you want it. Blood Snap stores the readings you confirm. Free metric reads, Pro two-way sync for blood pressure, sugar, weight, and sleep. Not a medical device.
