Blood Sugar Tracker (Digital Download)

A complete blood sugar log for adults with type 1 or type 2 diabetes. Log a reading from your phone in a few taps, watch the Dashboard update as you log, and bring one clean page to your next appointment. Works in Google Sheets (free) and Excel. Fingerstick, CGM or both. mg/dL or mmol/L.

Your numbers, your range, your file. No subscription, no ads, no account.

Light or dark, your choice

You get two versions of the same spreadsheet: Daylight (bright and clean) and Midnight (dark mode, easier on the eyes for late-night and overnight checks). Same tabs, same formulas. Use whichever you like.

FAQ

Does it suggest a target range?
No. The range fields start blank. You type the numbers your care team gave you, and the counts use them.

Does it calculate insulin doses or estimate A1C?
No. It logs and totals what you enter. Lab A1C results and CGM report numbers are recorded exactly as reported.

Can I use mmol/L?
Yes. Switch in Settings. Readings take one decimal.

Do I need a CGM?
No. Fingerstick, CGM or both. The CGM tab is optional.

Is my data private?
Your log lives in your own Google Drive or on your own computer. We never see it. Share a printed page or a PDF instead of an edit link.

Log and track only. Not medical advice. This tracker doesn't replace your care team. It does not calculate doses, give treatment or diet advice, estimate A1C or suggest targets. Always follow your care team's written plan.
