Blood Snap: log blood pressure, blood sugar & weight
in one diary.
Blood Snap is a premium health diary — no ads, ever. Core logging is free. Premium unlocks AI snap & voice, unlimited medicines with label scan, cloud backup, Google & Apple Health sync, and exports. Blood Snap is a personal wellness log, not a blood pressure machine, glucometer, or CGM. Charts show numbers you entered — not a diagnosis.
Blood pressure log: systolic, diastolic, and pulse.
Three big fields for a home blood pressure check. Start from yesterday's reading if you want. Add context — morning, evening, sitting or standing — so your blood pressure chart is a diary, not a guess.
- ✓ mmHg — systolic blood pressure, diastolic pressure, pulse
- ✓ Works with any home blood pressure monitor or cuff (you type or snap the screen)
- ✓ Left/right arm and posture notes
- ✓ Edit any past entry; full history kept
Blood sugar log with fasting and after-eating tags.
Pick mmol/L or mg/dL once. Tag fasting blood sugar, before meal, after eating, or bedtime. Optional insulin dose as a number you typed — Blood Snap does not prescribe. Charts compare the numbers you logged; they do not show clinical time-in-range bands.
- ✓ mmol/L and mg/dL, switchable
- ✓ Personal reminders when a value crosses a threshold you set
- ✓ Optional insulin dose and notes
- ✓ Log a number from a glucometer, glucose meter, or CGM display — the app is not a CGM
Snap a photo of your home monitor.
Photograph a blood pressure cuff, automatic blood pressure monitor, glucometer, or scale. On-device OCR first. If digits are unclear, a cropped image may be processed to suggest values — you always confirm before saving. Not Bluetooth. Not a medical device.
- ✓ On-device OCR first
- ✓ Optional AI vision fallback for number fill only
- ✓ Home blood pressure monitors, cuffs, glucose meters, scales
- ✓ Choose from photos or enter manually if the camera cannot start
Speak your reading. Review before you save.
Tap the microphone on the dashboard. Speech is recognized on your device, parsed into numbers, then shown on the same log form as manual entry — so you stay in control.
- ✓ On-device speech-to-text
- ✓ See transcript and parsed values before saving
- ✓ No ads anywhere in the app
A clear table of everything you logged.
Readings grouped by date. Filter by BP, sugar, or weight. Swipe to delete or tap to edit. Export PDF or CSV for a date range straight from History.
Blood Snap blood pressure and glucose charts.
Line charts for 7 days, 30 days, or 3 months. See averages, min, and max per vital from numbers you logged — no clinical interpretation and no “normal range” badge in the app.
Pill reminders that fit real routines.
Add medicines, set dose times, mark doses taken, and get local notifications. Works alongside check-in reminders and personal thresholds you set — not clinical high/low alerts.
How to log a consistent reading.
Tips for photographing a monitor, sitting still, and weighing at the same time of day. Not clinical ranges or diagnoses. Tips can be read in English or Urdu where translation is enabled.
