How to track resting heart rate on your phone

How to track resting heart rate on your phone, inside a blood pressure diary, starts with a limit: the phone app you open for the diary is not the sensor. Blood Snap can show the resting heart rate your health app already stored. It cannot feel a pulse, and it has no field where you type one in.

If you only have the number on the blood pressure cuff, save that as pulse on the blood pressure entry. That workflow is the pulse tracker with a home BP log. The steps below are for the separate resting heart rate metric.

What has to exist before Blood Snap can show a number

• On iPhone, resting heart rate samples in Apple Health. A watch that writes that type is the usual source. The iPhone step count alone does not create it.
• On Android, resting heart rate samples in Health Connect, written by whatever wearable or app you already allowed to record them.
• Permission for Blood Snap to read that type. The system sheet appears the first time you switch the metric on.

Blood Snap averages samples that fall on the same local day. One sample stays as that day's value. Several samples become their average. The unit on screen is beats per minute.

Turn it on in Blood Snap

1. Update Blood Snap, then open More Health.
2. Under Show on dashboard, switch on Resting heart rate.
3. Accept the Apple Health or Health Connect read prompt. If you previously denied it, turn the permission on in the system health settings and return to the app.
4. Open Home and pick a day that should have data. The card shows the rounded beats per minute, or a dash.
5. Open Insights and view blood pressure. The resting heart rate chart sits under the BP chart for the same period.

History can add the rate to the day line when a value exists. None of these screens store a copy inside Blood Snap. The read is repeated when you look. It is not uploaded to Groq.

iPhone and Android differences that matter

The switch subtitle on iPhone says the metric is from Apple Health. On Android it says Health Connect. The diary behavior is the same: read-only, free, and empty when the health store has nothing for that day. Two-way sync, which can write blood pressure, pulse, glucose, weight, and sleep back to the health app, is a different setting. It is Blood Snap Pro and stays off until you enable it. You do not need Pro to view resting heart rate.

Manual steps are the opposite kind of metric: you can type them for free in the free step log next to BP and sugar. Do not look for a similar box for heart rate. It is not there.

Keep the blood pressure log in the same habit

Tracking resting heart rate on the phone is a thin record if the cuff rows are missing. Log blood pressure with the routine in the home diary guide. Then use Insights to see the resting rate under that chart. The combined layout is described in the resting heart rate and blood pressure log.

Sleep and steps can be switched on beside it. They answer different questions. The overview is steps, sleep, and resting heart rate alongside blood pressure.

Fix an empty card before you blame the diary

1. Open Apple Health or Health Connect and check whether resting heart rate exists for that date at all.
2. Check that the wearable is worn often enough for its own app to compute a resting rate. Blood Snap cannot back-fill nights the watch missed.
3. Confirm Blood Snap's read permission includes heart rate data, not only steps.
4. Pull to refresh by leaving Home and opening it again on that day. The value is read when you view it.
5. If Insights says it could not read heart rate from Health, the permission or the health store connection failed. The blood pressure entries you already saved are unaffected.

What phone tracking cannot do

• It does not take a pulse with the camera, a finger on the screen, or the blood pressure cuff.
• It does not decide a healthy range or compare you with a population chart.
• It does not diagnose illness from a rise or fall across the week.
• It does not replace urgent care. Chest pain, fainting, a sudden severe headache, or severe breathlessness is an emergency, whatever the last number on the card was.

Track resting heart rate on your phone by reading the health app you already use. Switch it on in Blood Snap, then view it on Home and under your blood pressure chart. Free to read. Not a medical device.
