If you use continuous glucose monitors (CGMs) or are thinking about starting, you've probably realized that the key is no longer just having data, but knowing how to manage them with good appsToday there is no shortage of solutions: from apps connected to Dexcom, FreeStyle Libre or GlucoMen Day CGM, to cloud platforms and smartwatches that show you your glucose at a glance on your wrist.
The aim of this article is precisely that: to help you understand Which diabetes management apps are compatible with CGM sensorsWe'll explore what each app offers, what options exist for remote monitoring by caregivers or professionals, and how new AI-powered glucose prediction apps are gaining traction. Let's take a closer look, comparing features and providing practical, everyday examples.
Continuous and flash glucose monitoring: the foundation on which the apps work
Before discussing applications, it's important to understand exactly what these systems measure. continuous glucose monitors (CGM) and flash glucose monitoring systems They record the glucose level not directly in the capillary blood, but in the interstitial fluidThis is the fluid that surrounds the cells just under the skin. To do this, they use a small sensor that is inserted, for example, into the back of the arm or the abdomen and that sends data constantly or almost constantly to the receiving device.
In practice, this means that apps associated with these sensors can display continuous charts, trend arrows, and alerts for high or low levels, avoiding many finger pricks. In the case of systems of flash monitoringLike FreeStyle Libre, the sensor also measures continuously, but you need to scan it with a reader or a mobile phone to see the value; even so, the apps manage to present the history and patterns in a very visual way.
Menarini platforms: GlucoMen Day CGM, GlucoLog Web, GlucoLog T3 and Fitbit
Within the ecosystem of apps compatible with CGM, one of the most complete systems is that of A. Menarini Diagnosticswhich has created a suite of digital solutions around its GlucoMen Day CGM sensor and other devices in the GlucoMen range. Their idea is clear: to combine specific medical technology with everyday digital platforms so that diabetes management made simple and accessible, both for the person with diabetes and for their environment.
GlucoMen Day CGM: continuous monitoring on your mobile device
The sensor GlucoMen Day CGM It sends data minute by minute to an app installed on the smartphone or tablet, which acts as a receiver. From this app, the user can view the current glucose level, trend arrows, graphs of the last few hours, and configure settings. custom alerts for hypoglycemia or hyperglycemia. Once you get used to it, it's very common to think: "How could I live without this?"
This app is the starting point, but its true power comes when data is shared with the cloud. Through integration with Glucolog Web and other tools, the user and their medical team obtain a much more complete analysis of what is happening with glucose on a daily basis.
GlucoLog Web: Diabetes management in the cloud
GlucoLog Web It is the online platform where data from the GlucoMen family of devices (GlucoMen Day, GlucoMen areo, etc.) is centralized. Instead of remaining only on the mobile device, the readings are sent to the cloud and stored securely, so that you can Access from any device with an internet connection using username and password, without needing to install anything else.
The great advantage of this system is that it allows analyze and share data in real timeGlucolog Web generates statistics, reports, and graphs that help identify patterns, trends, and times in range, which is very useful for adjusting treatment and improving metabolic control. Furthermore, the user decides who to share the information with: healthcare professionals, caregivers, or family members.
Another key aspect is that the data is updated almost minute by minute with the sensor readings, so that the medical team or reference people can see the same information as the user almost in real time, something especially relevant when they want to detect control problems or assess changes in the insulin regimen.
GlucoLog T3: remote monitoring of family members and new patients
La app Glucolog T3 It is designed for those who need or want to remotely monitor someone using GlucoMen Day CGM. Parents, partners, or caregivers can view the information on their own mobile device. real-time glucose readings of the connected person, provided that they have authorized access.
This can make a big difference, for example, in newly diagnosed diabetesThe first few months after diagnosis are often filled with doubts, changes in routine, and fear of hypoglycemia; having someone you trust who sees the same data and can provide guidance or react to a drop in blood sugar offers great peace of mind. If a hypoglycemic episode occurs, the caregiver can detect it thanks to the graph and alerts. to act quickly.
In addition, Glucolog T3 allows configuration own and independent alarms of those that are adjusted in the user's CGM. This means that the caregiver can set different glucose ranges, adapted to their judgment, and receive alerts for spikes or dips that the user may not have configured as critical.
Fitbit display: wrist glucose
Another strength of the Menarini ecosystem is its integration with Fitbit smartwatches (models like Ionic, Versa, or Sense) through a specific clock face. Once paired, the watch displays the current glucose value in the interstitial fluid, the trend arrow, and the profile of the last 4 hours, along with steps and heart rate recorded by Fitbit itself.
This setup is ideal for active people and athletes because it allows you to check your glucose levels at a glance without taking your phone out of your pocket or unlocking it. Simply turn your wrist to see your current glucose range and direction, making it easy to make immediate decisions about carbohydrate intake or insulin.
The Fitbit watch can also be used for remotely monitor another person that carries GlucoMen Day CGM. By entering the appropriate credentials, the evolution of a family member's or patient's glucose levels can be monitored directly from the wrist, reinforcing the idea of technology that improves the quality of life for both the patient and their environment.
Other apps compatible with or designed for CGM: Dexcom, FreeStyle, LinX CGM, and more
Beyond the Menarini ecosystem, the market offers a wide range of applications specifically designed for continuous glucose monitors, each with its own approach. Some are tightly integrated with a particular device, while others act as complementary platforms that add layers of analysis, prediction, or recording capabilities.

It also allows you to export information in different formats to bring complete reports to endocrinologist appointments. It even includes specific functions for women with gestational diabetes, something still uncommon in the app landscape.
As an added benefit, it integrates with Apple Watch and Siri widgets, so you can check your glucose and other data without having to open the app in the traditional way, which greatly speeds up daily use.
Dexcom G7 app
La Official Dexcom G7 app It is the central component of the system for those who carry this CGM. Its philosophy is to offer a clear, simple, and real-time visualization of glucose, with predictive alerts that warn of possible hypoglycemia or hyperglycemia before they occur.
The app allows you to share reports and data with caregivers or healthcare professionals, which is very useful for medical checkups or remote monitoring. Its main strength is... native integration with the sensor itself and a highly refined alert system that helps in making proactive decisions.
FreeStyle Libre and FreeStyle LibreLink / FreeStyle Libre 3
In the case of Abbott, we have several specific applications aligned with its ecosystem. On the one hand, FreeStyle LibreLinkdesigned to work with the sensors FreeStyle Libre and FreeStyle Libre 2It allows you to scan the sensor with your mobile phone and obtain the current glucose value, trend arrow and history, without needing to use a dedicated reader.
On the other hand, the app of FreeStyle Libre 3 It integrates with Abbott's latest continuous glucose monitoring sensor, which sends glucose readings directly to your smartphone. This solution is designed to offer a Affordable and highly automated MCGAnd in many countries it is one of the most economical options on the market, costing less than $40 a month with insurance.
In both cases, the apps allow you to generate graphs and reports and, depending on the configuration, share information with professionals or caregivers for closer monitoring.
Sugarmate and other apps connected to the Dexcom ecosystem
Sugarmate It's a very popular app among Dexcom users looking for a alternative interface to the official app. It focuses on simplifying glucose level tracking, with clean graphs, integration with other devices, and the ability to receive notifications in various formats.

LinX CGM: app dependent on external hardware
LinX CGM It is a mobile application designed for receive and display glucose readings Data is collected from an external Bluetooth-based continuous glucose monitoring device. The app allows users to set high and low limits and receive reminders when glucose levels fall outside the preset range, in addition to offering basic analysis and reporting tools.
It is important to note that LinX CGM, in itself, it is not a medical device It does not function without compatible hardware. Its purpose is to serve as an interface for viewing and analyzing wellness data, and it should never be used on its own to diagnose or adjust treatments without the supervision of a healthcare professional.
Diabetes apps certified and endorsed by health authorities
A logical concern when we talk about health apps is knowing if they meet minimum quality, safety and reliability standardsIn this regard, the TIC Salut Social Foundation in Catalonia has developed a mobile app certification service that reviews aspects such as usability, accessibility, security, technology, and content.
Among the apps that have passed this process and are related to glucose monitoring, many are compatible with monitoring devices (CGMs or glucometers). All are free and allow users to record blood glucose levels, weight, medication, and other parameters, in many cases using data from a computer.

Other noteworthy applications include stinksdiabetes, promoted by the Spanish Diabetes Federation, which combines a medication diary, blood pressure and glucose monitoring with an appointment reminder calendar and insulin administration; Center Healthwhich offers real-time statistics (daily, weekly, monthly, quarterly) and a barcode reader to calculate carbohydrates; and again One Touch Reveal, which synchronizes with its meters to identify patterns of rises and falls according to daily activities.
Glucose prediction apps and artificial intelligence: a step beyond CGM
While continuous glucose monitoring already represented a huge leap in the quantity and quality of available information, the next level is being marked by... glucose predictor apps Based on data mining and machine learning techniques, these applications do not simply display the current value and immediate trend, but rather seek anticipate glucose levels several hours in advance and estimate the effect of specific actions such as a meal or a particular exercise.
The value of these predictions is twofold. On the one hand, they are a fundamental component of the systems of closed-loop handle that automate insulin infusion; on the other hand, they can simplify everyday decision-making (what to eat, when to correct, how much glucose to take in case of a drop) and improve glycemic control results in people who do not use an insulin pump.
Basics of glucose prediction: data, models and machine learning
For these apps to work, they need to build a large volume of personal health data (Big Personal Health Data): continuous glucose monitoring, insulin doses, carbohydrate, protein and fat intake, food types, physical activity, dreamStress and other factors influence blood glucose levels. The more reliable and complete this data is, the more accurate the predictions can be.
As for predictive models, they usually combine three approaches: models based on the physiology (which simulate the behavior of glucose metabolism, insulin, and food absorption), models empirical based on historical data from the patient themselves (the so-called black boxes) and hybrid models that mix both approaches to improve robustness.
The techniques of machine learning algorithm The most commonly used methods include artificial neural networks, support vector machines, evolutionary grammar, and decision trees. In particular, neural networks are used to "learn" from data without explicitly programming the system with a solution, somewhat emulating how a human brain learns from experience.
The accuracy of these predictions is assessed using both mathematical metrics (e.g., the root mean square error) and clinical tools (such as Clarke or Parke error analyses), but a single, universally accepted standard still does not exist. Furthermore, challenges such as the inherent delay of CGM systems and the accuracy of user-entered data come into play.
Examples of glucose predictor apps
Although they are not yet widespread and in many cases are only available in certain countries, there are already applications that put these ideas into practice and integrate with commercial CGMs or platforms like Nightscout.
Diabits It's an app that reads CGM data from the Dexcom G6 app or Nightscout and displays both real-time glucose and a Prediction of glucose behavior in the next 60 minutesIt allows you to manually enter information about meals (including carbohydrates, proteins, fats and glycemic index), insulin doses, exercise and other events to refine predictions.
One of its most powerful functions is the Prediction of nocturnal hypoglycemia up to 8 hours in advanceThis can provide considerable leeway for adjusting dinner, basal glucose levels, or consuming extra carbohydrates. Each week, it generates a summary report with time in range, average glucose levels, and trends, and allows users to add followers (family or professionals) who can view the predictions. It utilizes support vector machine learning and graded decision tree techniques, and published studies show significant increases in time in range when the user frequently consults the app.
January AI It focuses particularly on the glucose-diet relationship. After an initial learning period with CGM data, it is able to predict glucose behavior even without continuous dataIt uses information on heart rate, physical activity, and meals. It includes a huge food database (millions of entries) and offers guidance such as how much physical activity would be recommended after a specific meal to keep glucose within range.
La app Which oneAvailable in some European countries, it is designed for people who administer multiple daily insulin injections (MDI) without other medications. It predicts blood glucose levels over a horizon of approximately 5 hours and helps calculate insulin doses Based on the context. According to data reported by its users, a high percentage manage to increase time in range, reduce episodes of hypo- and hyperglycemia, and feel more relaxed about managing their diabetes.
Final considerations
Lastly, PredictBGL It offers predictions up to 8 hours in advance and a bolus calculator that considers physical activity, the fat and protein content of meals, and active insulin. It can provide guidance on the adequate amount of glucose in cases of hypoglycemia and on the ideal timing between insulin injection and food intake in cases of hyperglycemia. It incorporates a very extensive food database, which makes it easier to refine the calculations.
This entire ecosystem of predictive apps, along with CGM systems and remote monitoring platforms, is transforming how people with diabetes and their healthcare teams make decisions. With more data, better analyzed and presented clearly and usefully, it becomes much easier to achieve a better outcome. strict glycemic control and reduce the risk of long-term complications, while also considering the emotional impact of daily life.
With the current range of apps compatible with CGM sensors—from official tools from manufacturers like Dexcom, Abbott, or Menarini, to certified platforms like SocialDiabetes, FreeStyle Libre 3, or Eversense CGM, to advanced prediction solutions like Diabits or January AI—any person with diabetes can build a customized “digital ecosystem” that helps them better understand their data, share it with whomever they need, and make more informed decisions without unnecessarily complicating their life.Share this information so that more users can learn about the topic.
