Readband: BP & Sugar Log

Readband is a blood pressure log and blood sugar log for the numbers your monitor or glucose meter already shows. It does not take readings with your phone. You type the numbers, it keeps them tidy.

Log in 3 seconds
Tap + Log BP, type systolic, diastolic and pulse on the big keypad, save. Fasting, before meal, 2h after meal or bedtime sugar works the same way.

See the reference band right away
Every reading lands on a color band: low, in range, elevated or high. The default ranges follow public AHA blood pressure categories and ADA glucose guidance. You can edit every number with your care team. For reference only, not a diagnosis.

Your history in one place
- 7, 30 and 90 day charts for blood pressure and blood sugar

- Share a summary card or export CSV before a doctor visit

Built to be a quiet tracker
- No account, no sign-up. Records stay on this device.
- Only one optional permission: reminder notifications.
- No launcher changes, no pop-ups outside the app.
- Morning and evening reminders you can turn off anytime.
- Home screen widget: latest readings plus one-tap + BP and + Sugar.

Who it is for
People with hypertension or diabetes who want a simple hypertension tracker and glucose tracker, and family members keeping a BP diary for a parent.

Readband is a record-keeping tool, not a medical device. If your numbers worry you, talk to a healthcare professional.
