Start NowWhat changed this week
These are the three changes in Blood Sugar - Diabetes App 1.3.9 that stand out in the developer's update notes and on its Google Play listing this week.
- 01Fixes and stability work
The latest build's notes cover fixes and stability work. That is a general maintenance focus for an app used to enter and revisit personal glucose readings.
- 02Worth using: tagged reading logs
Add a reading and attach a tag for context, such as before or after a meal, fasting, taking insulin, medication, or mood. That context makes entries easier to review.
- 03Worth using: charts and unit conversion
Review glucose history in charts and switch between mg/dL and mmol/L with a tap. These tools make it easier to view recorded values in a familiar format.
Our call on whether to update, and the link to the official Google Play listing, are on this issue's Blood Sugar - Diabetes App page.

Tips
- Add context to each reading
When you record a glucose value, add a tag that explains its context, such as fasting, before or after a meal, or taking insulin. Custom tags can make a history more useful to discuss with a clinician. Choose labels that reflect your own routine, and remember that the app records readings rather than measuring them.
- Review your history in charts
Open the chart view to look across your recorded glucose readings and notice how values change over time. A chart can make a long list of entries easier to scan, while the underlying records provide context. Use the app's analysis as an aid to understanding readings, not as a diagnosis or a replacement for medical advice.
- Choose a familiar glucose unit
Use the one-tap unit switch to view blood sugar values in mg/dL or mmol/L, whichever format is more familiar to you. Keep the unit in mind when comparing records or sharing a report with a doctor. If you are unsure which format to use, ask your health professional rather than interpreting a reading on your own.
Menu names follow the developer's help pages and can differ slightly between versions and phones.
How we write the digest
Each week we check the Google Play listings of the apps our readers use most: the version number, the update date and the developer's What's new notes. When an app has a new version, we put the developer's update notes and the listing details together on one page, in plain words, with a link to the official Google Play listing. Google and most developers release updates in stages over several days, so a version listed here may not have reached your phone yet. Select Weekly is an independent site and is not affiliated with any developer. This page doesn't read your phone or your Google account, and nothing is installed from here.
FAQ
Is this the official list of Blood Sugar changes?
No. This is an independent site and is not affiliated with QR Code Scanner. The app's Google Play page is the authority for its listing and current update information. This editorial summary is intended to help explain the app's described tools and the update's general focus; refer to Google Play for the official app details.
Why does Google Play show Open instead of Update?
Google Play may show Open when the latest build is already available to the account, or before an update reaches everyone during a staged rollout. Check the app's Google Play page again later if you expected an update option. Availability can vary, so seeing Open does not by itself mean that something is wrong with the app.
Can Blood Sugar measure glucose by itself?
No. Blood Sugar is described as a tool for recording and reviewing blood glucose readings; it does not measure blood sugar. You enter readings and can add context tags, view charts, and use the app's analysis. For interpreting results or deciding what action to take, rely on guidance from a qualified health professional.
