8. LibreLink

Availability: Android, iOS

Features: Exclusive to users of the FreeStyle Libre sensor, the app allows View the value measured by the sensor on your cell phone., With a simple touch of proximity. It's worth emphasizing the division of roles: the measurement comes from the sensor applied to the skin; the phone acts as a display and as a recorder. It automatically stores data, displays trends and personalized alarms. It has synchronization with LibreView, which can be accessed remotely by doctors.

Who measures, who records, who decides

This is the part that almost no list explains, and it's what avoids frustration when choosing. Diabetes management relies on three components with different functions:

• Who measures: The glucometer's reagent strip or continuous monitoring sensor. The measurement is a chemical reaction — the enzyme on the strip reacts with glucose and generates an electrical current that the device reads. Without a sample and without reagent, there is no reading.
• Who registers: The app stores the value, cross-references it with meal, dose, and exercise, draws the graph, and generates the consultation report.
• Who decides: The healthcare team. Dose, schedule, and goals are determined during the consultation, based on what the report showed.

Therefore, none of the apps on this list measure blood glucose via mobile phone — and no reputable app claims to. If you find one that promises readings via camera, flash, or fingerprint, without a test strip or sensor, you can close it: there's no physical basis for it, and a fabricated number disguised as a test result is dangerous for those who use insulin.

Interesting Extra Features

• Connection with Apple Health and Google Fit: Integration with step, exercise and sleep data for more complete control.
• Exporting reports: Essential tool to show progress to the doctor.
• Remote monitoring: Possibility of sharing data with caregivers or family members.
• Carbohydrate Calculator: Essential for insulin and diet adjustment.
• Offline mode: Most apps allow use even without internet, with subsequent synchronization.

Common Care or Mistakes

• Trust the app only: Always consult your doctor for treatment decisions.
• Incomplete records: The more complete the data entered, the more useful the reports will be.
• Ignore alerts: Reminders are important to maintain regularity of treatment.
• Do not use sharing features: Sending reports to your doctor can speed up adjustments to your treatment plan.
• Install untrusted apps: Choose apps that are well-rated in official stores to ensure security.

Interesting Alternatives

• Excel Spreadsheets: Useful for those who prefer manual and personalized control.
• Physical diaries: Still effective for quick and simple note-taking.
• Continuous monitoring sensors: A thin filament under the skin measures glucose for several days and sends the value to a cell phone or watch. Beware of a common misconception: The sensor is what measures it. — The smartwatch only displays the reading. Currently, there is no watch that measures blood glucose without a sensor and without finger pricking.
• Paid digital consultancies: Apps with support from nutritionists and diabetes educators via chat.
• Medical plan health programs: Many offer their own apps with features similar to market leaders.

Which of these profiles is yours?

Installing eight apps to decide on is the quickest way to avoid having a history with any of them. Instead, identify your profile and test two, at most, for a week each.

Those who use insulin in multiple doses per day.

What matters here is the speed of data entry and the ability to record carbohydrate and dose along with the value, as well as clearly marking episodes of hypoglycemia. Calculation tools only make sense if they can be configured exactly according to the scheme prescribed by your team — and the verification remains human.

Those who take pills and measure only a few times a week.

Here, the app needs to be simple and not penalize absence: no empty, demotivating graphs. What matters is the monthly record, the observation field, and the ability to record weight and blood pressure in the same place, because these numbers are read together during monitoring.

Who uses continuous monitoring sensors?

The sensor brand's app already provides the reading. What's often missing is a record of what happened around that number—meal, exercise, illness. Many people use the sensor's app to see the reading and a separate recording app to note the context.

Someone who takes care of another person.

Look for multiple profiles, invitation-only sharing, and person-based reporting. And check beforehand if you can revoke someone's access without deleting their history.

Those who just want to arrive at the appointment in an organized way.

If that's the goal, then the virtually sole criterion is exportability. A modest app that generates a clean PDF is worth more than one full of features that only displays it on the screen.

Why does the app reminder sometimes not ring?

This is the most common complaint from those who rely on the alarm to measure or take their medication, and it's almost never a problem with the app. Modern systems close inactive apps to save battery, and the reminder dies along with them. It's worth checking, in this order:

1. Notification permission granted. In recent versions of Android, it is requested only once, and those who reflexively refuse will never have an alarm.
2. Battery restriction disabled for that app. In the app settings, look for the battery usage option and choose the unrestricted mode. This setting resolves most issues.
3. Precise alarms allowed. Some systems require separate authorization for an app to launch at a specific time instead of "around".
4. Do Not Disturb mode with exception. If you sleep with sleep mode on, the midnight reminder won't sound unless that app is on the exception list.
5. Focus and summary of notifications. Features that group notifications for later delivery delay precisely what needs to arrive on time.
6. Memory cleaners. An app that "optimizes" your phone by closing processes is the silent cause of missed reminders.

After adjusting, do a real test: set a reminder for five minutes from now, lock the screen, and put the phone aside. If it doesn't ring, the problem is with the system, not your memory.

What to do if the app goes offline.

A health app disappears. The company is bought, the developer abandons the project, the app is removed from the store due to incompatibility, or the free model becomes a subscription overnight. Those who have been registered for years discover the problem at the worst possible time.

• Export from time to time, out of habit. One CSV file per quarter saved in your email or cloud storage is all you need. It's the difference between migrating and starting over.
• Give preference to those who record data on the system's health dashboard. Thus, a second copy of the values exists outside the application, which any successor can read.
• Be wary of closed formats. Backups that only the app itself can open are for reinstalling the same app, not for switching apps.
• When switching phones, migrate before deleting the old one. Install the new app, confirm with your own eyes that the history has appeared, and only then perform a factory reset on the old device.
• If the app disappears from the store but is still installed, do not uninstall it. Open it, export everything you can, and only then remove it.
• Request account deletion. Abandoned services often leave the database active for years. If there's a channel to request deletion, use it while it's still responding.

Questions about data, cost, and compatibility.

Does the app from my device's manufacturer work with devices from other brands?

Generally, automatic synchronization doesn't work—each manufacturer handles it with their own products. Manual registration, however, works with any brand in any app.

Is it worth paying for a diabetes app subscription?

It's worthwhile when the paid feature solves a concrete problem you've already had: a report your team requests in a specific format, automatic backups, or more than one profile. Subscribing to a feature that "might be useful someday" is a recurring expense without any return.

Could the data I record end up with a health insurance plan?

They shouldn't, without your explicit consent. The point of attention is the applications offered by your carrier or employer, where sharing is part of the service design. Read what you agreed to when you signed up.

Do I need to create an account or can I use it without registering?

Several options operate locally, without an account. This is the least exposed option, but with a clear cost: without an account, there is no cloud backup, so manual export becomes mandatory.

Is the application in English a problem?

It hinders both maintaining the habit and the professional's ability to read the report. If both things matter to you, this is a criterion as practical as any other feature on the list.
