Temperature Monitoring

MedAngel ONE always shows you the exact temperature with colourful symbols, at home, on the go or while travelling. At one glance, you can see when all is well (green heart), too warm (red heart) or too cold (blue heart).

Smart Alerts

A fridge door left open on a hot summer day? MedAngel ONE triggers an alarm if the temperature is critically out of range. The app warns you whenever the temperature approaches or exceeds the optimal temperature range. This can be a simple reminder to check the fridge door or to move a cool bag out of the sun.

Medication Specific

Simply choose your medication in the app and the specific optimal temperature ranges for that medication are automatically set up. Select long term storage or short term carrying mode to obtain the right temperature ranges for your use. All insulins, wide range of biologics, hormones and other injectables are supported.

Long Lifetime and Waterproof

The MedAngel ONE temperature sensor is powered by a standard coin cell battery which lasts for 8-9 months. Simply replace it yourself and make your sensor last for years. The app will notify you when you need to replace your battery. MedAngel ONE is also waterproof so you can store it in the fridge or carry it in medical cool bags.

How it works

Download the MedAngel ONE app on your compatible smart phone today through The App Store or Google Play.

  1. MedAngel ONE consists of a wireless thermometer and an app for iPhone and Android that monitors the temperature of your medication.
  2. The MedAngel ONE sensor is meant to be kept with your medications as it continuously measures the temperature at which they are stored. The MedAngel ONE app shows you the current temperature and alerts you when the optimal temperature range of your medication is exceeded, so that you can take action.
  3. A timeline helps you track temperature changes over the course of the last 30 days.

Frequently Asked Questions

Why should I use MedAngel ONE in my refrigerator?

For long term storage of most temperature-sensitive medications, 2 to 8°C is the recommended range, which should be compliant with the temperature in a refrigerator. However, many domestic refrigerators have internal warm or cold spots, or wide variations in overall temperature, so medications may be exposed to temperatures outside the recommended range.


It’s not all that complex. Often, it is enough to move your medications to a different shelf or to adjust the settings. Use MedAngel ONE to find the perfect spot in your fridge for your medications and keep on eye on it during seasonal changes!

How many MedAngel ONE sensors do I need? Can I connect multiple phones to one sensor?

That depends on your medications and on your lifestyle. Most of our insulin users, for example, have two sensors: one for their insulin in use, that they carry around with them during the day and one for their stock in the fridge at home. You might want to use only one sensor to put with your medications in your fridge and occasionally take with you in a cool bag, or you might also want to use two sensors to check on medications both at home and in your office fridge.


MedAngel ONE should be paired with one phone, and connecting it to two phones is less ideal. The temperature sensor broadcasts temperature data via Bluetooth and the closest phone will receive it. This means that data might be end up scattered across two different phones. The timeline view, for example, would not be complete on either of them.

Can I track multiple medications with one MedAngel ONE sensor?

The MedAngel ONE sensor continuously measures temperature and is kept with the medications you want to monitor. If you are keeping multiple medications in one place, like your fridge, it makes sense to select and attribute them to one sensor in the app. The MedAngel ONE app will give you medication-based notifications, so if the temperature is critical for one of your medications but not for the others, you will only get an alert for that particular one.

Is the mobile app free?

Yes, the MedAngel ONE app which is to be used together with the temperature sensor is available to download for free on the Android Play Store and the App Store for compatible iPhone and iPad. By purchasing the MedAngel ONE sensor, you can use all functions of the app and there will be no in-app purchases or any other extra cost for using it.

Do I need an internet connection for the app to function?

No internet connection is required for the app to function, since the temperature sensor and the app are connected via Bluetooth. This means that you can also use MedAngel ONE on flights, while your phone is in Flight Mode. However, you will need to be connected to the internet to do the following:

  • Set up the app for the first time by signing up and confirming your email
  • Checking out the help manual and contacting MedAngel


If you log out of the app for any reason, you will have to be connected to the internet to log in again and continue using the app and sensor.

Do I need to be near my MedAngel ONE in order for it to work?

The MedAngel ONE sensor has an internal memory for temperature data for up to one week. When the sensor and your phone are not within Bluetooth range or when your phone is turned off or you are logged out from the app, you will not be able to receive the current temperature data from the sensor. When this happens, the MedAngel ONE sensor saves that data and transmits it to the app as soon as sensor and phone are connected again.

What are the different use modes in the app?

Many medications are stored in the fridge, which should maintain a temperature of 2 to 8°C, but some can also be removed from the fridge and stored at room temperature (usually up to 25°C) for a limited amount of time. MedAngel ONE knows the safe temperature ranges for your medication for both long-term and short-term storage. Simply select your use mode in the app by choosing either ‘storing’ or ‘carrying’ and the temperature ranges will adjust accordingly.

What kind of battery do I need for my MedAngel ONE sensor?

The sensor is powered by a lithium-Ion CR2032 battery. These are standard batteries that you should be able to find in any electronics store. It is important to get lithium batteries since alkaline batteries will not perform that well in a refrigerator.
