Doctors ask “what were your readings this month?” and a list beats memory. Write down each blood pressure, blood sugar or weight reading in seconds, with the date, time and a note. The log draws a chart of your recent readings, shows a 30-day average and explains each reading in plain words, then gives you a neat file to show or send to your doctor.
loading toolHow to keep a health log
- Choose BP, Sugar or Weight.

- Measure BP at the same times each day, after sitting quietly for five minutes, with your arm at heart level.
- For sugar, choose Fasting for a morning reading before food and After meal for two hours after eating.
- Add your height once to see your BMI with each weight reading.
- The chart shows your last 30 readings of the type you choose.
Questions
Where is my data saved?
Only in this browser on this device, the way a chat app keeps chats on your phone. Nothing is uploaded and there is no account. Use Backup to save a copy as a file (Restore brings it back, even on another phone or computer), and back up before clearing your browser data. The My Data tool backs up every record tool in one go.
What do the words like “Elevated” mean?
They follow widely used adult ranges: blood pressure under 120/80 is normal, 120–129 upper is elevated, 130/80 and above is high. Fasting sugar under 100 mg/dL is normal, 100–125 is the prediabetes range and 126 or more is the diabetes range. Your doctor may set different targets for you.
Can it replace my doctor?
No. It helps you keep accurate records. Always talk to your doctor about your readings, and get medical help at once if a reading is very high or you feel unwell.
My meter shows mmol/L. What do I do?
Multiply mmol/L by 18 to get mg/dL (for example 5.5 mmol/L ≈ 99 mg/dL), then enter that number.
Is my data private?
Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.
Is it free?
Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
