Health Diary by MedM

Review by eFreeware

MedM Health is a health diary app from MedM Inc, listed under Medical on Google Play. It is built around one idea: keeping measurements such as blood pressure, glucose, weight, temperature, heart rate and oxygen saturation in a single place instead of scattered across paper notebooks and separate device apps. The developer describes it as a holistic monitoring diary rather than a simple logbook, and the breadth of what it records is the main reason to consider it.

The app is free to download and carries no ads, though it offers in-app purchases and some features sit behind a subscription. With more than 100,000 installs and a 4.5 average from 5,292 ratings, it has clearly found an audience among people who track health data regularly. It has been on the store since May 2014 and was last updated in October 2026, with the most recent change noted as minor improvements.

What separates MedM Health from a plain spreadsheet is its connection to hardware. The developer says it can collect more than 25 measurement types from over 1,000 Bluetooth-enabled sensors, and that it supports Bluetooth, NFC and ANT+ meters from a long list of manufacturers including Omron, A&D Medical, Beurer, Masimo, Nonin, Roche and Tanita, among many others. If you already own a compatible blood pressure cuff or glucose meter, that automatic collection is the feature that matters most.

What you can actually record

The parameter list is unusually long. Alongside the obvious ones, the app covers blood cholesterol, blood coagulation, creatinine, ketone, lactate, uric acid, A1C, hemoglobin and hematocrit. It also handles ECG, spirometry, fetal Doppler, mole scan and auscultation readings, plus lifestyle entries such as activity, exercise, sleep, stress level, water intake, calories consumed, carbohydrates, alcohol content and medication intake. There is even a plain note type for anything that does not fit elsewhere.

That range is the point. Someone managing a chronic condition often needs to log several things at once, and the app is designed so those readings live together rather than in separate tools. The developer pitches it as useful for reaching wellness goals, managing a chronic condition and improving quality of life, and the structure supports all three, though the wellness framing is the one the app itself is careful to stay within.

It is worth being clear about the intended scope. The app is described as being for non-medical, general fitness and wellness purposes, and the developer advises consulting a doctor before making medical decisions. That does not make the data less useful, but it does mean the app is a record-keeping tool rather than a source of medical advice.

Automatic collection and manual entry

Readings can arrive two ways. Connected fitness and health monitors can feed data in automatically, and the app supports an unlimited number of connected meters, so a household with several devices is not constrained. Readings from a basic cuff or scale that has no compatible device can still be entered by hand through the Smart Entry interface, so the app stays usable.

Once data is in, the app offers a configurable dashboard, a measurement history, trends and graphs. That combination is what turns a pile of numbers into something you can look at over time, and it is the part I would expect most people to check regularly. Reminders for taking medications and for making measurements are included as well, which helps when the routine depends on remembering to take a reading at a set time.

A list on the MedM website shows which devices work with the app, so compatibility can be checked before you commit. Doing that first is sensible, because the value of automatic collection depends entirely on whether your meter is on it. Manual entry remains the fallback for everything else.

Registration, backups and what Premium adds

MedM Health can be used with or without registration. Without an account, everything stays on the phone and nothing is uploaded. Registering brings synchronization and backups through a cloud service, so the record survives a lost or replaced handset. Cloud sync uses HTTPS, and the servers holding the encrypted data are hosted securely. The app does not sell or pass on health information without permission. Users can export their records or ask for them to be deleted.

Some features require a subscription and registration. A two-week free trial of MedM Health Premium is offered so the paid side can be tried before committing. Premium adds multiple health profiles for a family, including pets, which is the feature that turns this from a personal log into a shared one.

Premium also covers data sync with connected health ecosystems such as Apple, Garmin, Google, Samsung and Fitbit, profile sharing, remote health monitoring through the app or the MedM Health Portal, notifications for thresholds, reminders and goals, and export in PDF and XLSX. CSV export is available in the basic feature set, which is enough for anyone who wants to move raw numbers into a spreadsheet.

Setting up and what you need

Getting started is a matter of deciding how you want to run it. The app works without an account, in which case everything stays on the phone, or with one, which enables cloud sync and backups. There is no registration requirement to begin logging, which lowers the barrier for anyone who wants to try it before handing over an email address.

If you plan to use connected meters, check the compatibility list on the MedM site first. The app supports Bluetooth, NFC and ANT+ devices from a wide range of vendors, but the list is the authoritative source for whether your specific model works. Setting up the hardware side before building a routine around it avoids disappointment.

The Premium trial is the other thing to plan around. Two weeks is enough to see whether multiple profiles, ecosystem sync or remote monitoring are worth paying for, and the basic features remain available without them. I would treat the trial as a way to test the parts that matter to your situation rather than as a reason to subscribe by default.

Families, caregivers and solo trackers

The app seems best suited to two broad groups. The first is someone managing a long-term condition who needs to record several measurements consistently and show them to a clinician. The second is a family or caregiver looking after someone else's readings, where multiple profiles and profile sharing make the app a shared record rather than a private one. The inclusion of pets in the profile system suggests the developer expects households to use it broadly.

Solo users who simply want to watch weight, activity and sleep will find plenty here too, though the depth of the parameter list is more than that use case needs. The dashboard, trends and reminders are the parts that carry over well to a lighter routine.

Anyone whose main interest is a single metric, or who has no compatible measuring device and no intention of entering data by hand, will get less from it. The app is built for people who collect readings regularly and want them in one place.

A connected diary for people who measure often

MedM Health is a mature, broad health diary with an unusually strong hardware story. Automatic collection from a large catalog of Bluetooth, NFC and ANT+ meters, a long list of trackable parameters, offline use without registration and cloud backup when you want it add up to a tool that fits real routines rather than idealized ones. The absence of ads is welcome in a category where they are common, and the free tier covers the core logging job.

The trade-offs are the subscription for the family and sync features, the need for compatible equipment to get the most from automatic collection, and the fact that the app is explicitly a wellness tool rather than a medical one. None of those are surprises, but they shape who benefits most.

I would suggest it to anyone who measures regularly, especially those juggling several readings or keeping an eye on a relative's health. If your routine is occasional and single-metric, a simpler log may serve you just as well.
