Trying to decide between Life Alert vs. Medical Guardian? They’re two of the most well-known medical alert systems on the market. But which is better? That depends on your individual needs.

In general, medical alert systems use a small base unit paired with a wireless help button (for at-home systems) or a mobile device (for on-the-go systems) to connect to a company’s 24/7 monitoring center using a landline or cellular network. When you press the device’s help button, you connect to the monitoring center, where trained operators dispatch emergency services if you need them.

Why we chose to review Life Alert vs. Medical Guardian

To help you decide which medical alert system is best for you, we compared two well-known companies. We chose Medical Guardian for its premium features and Life Alert for its name recognition. To see how these brands stack up against each other, we gathered as much information as possible on their special features, the costs of medical alert systems, and customer experience.

Our Reviews Team surveyed 1,000 medical alert system users and found more than 82% of Medical Guardian users say they are happy with their medical alert system purchase, compared to 64% of Life Alert users.

If neither Life Alert nor Medical Guardian is a good fit, there are several other medical alert systems to consider. For example, in our list of the best medical alert systems, MobileHelp was our pick for “Best All-Around System,” Bay Alarm Medical was “Best for the Price,” and LifeFone was “Best for Customer-Friendly Policies.”

Medical Guardian

Medical Guardian medical alert system


  • Doesn’t require long-term contract and offers options for monthly, quarterly, and annual payments
  • Free activation and installation with no hidden fees
  • Fast response time (1–15 seconds)
  • Long device range (1,400 feet)
  • Refundable prepaid plans
  • Offers promotional discounts occasionally
  • Fall detection available for an additional $10 per month
  • Offers Limitless Icons accessories that make your medical alert device look like jewelry


  • Equipment purchases are required for some plans
  • May require a restocking fee of up to $50 if you cancel the subscription
  • Batteries need recharging every 1–5 days, depending on the device

Although Medical Guardian is less well known and younger than Life Alert (Medical Guardian was founded in 2005, and Life Alert in 1987), the company has established itself as one of the top medical alert system companies.

Medical Guardian offers five different devices, including one smartwatch option, and the ability to add fall detection (for an extra cost) to four of its five products. 

Its five main options include the following:

  • Two at-home models: 
    • Home 2.0
    • Classic Guardian 
  • Three on-the-go models: 
    • MGMove
    • Mobile 2.0
    • Mini Guardian

To assist users in finding the plan and device that is right for them, Medical Guardian has a product quiz on its website to help narrow down the available options. 

Unlike Life Alert, Medical Guardian requires no contracts, so you can cancel anytime. Medical Guardian also has one of the fastest response times in the industry—our Reviews Team tested Medical Guardian devices and found an average response time of 1–15 seconds, well below the 30-second industry average based on our internal testing. 

It also has one of the longest device ranges in the industry at 1,400 feet (almost four football fields), compared to Life Alert’s maximum of 800 feet. Device ranges specify how close you need to be to the base unit (for at-home systems) for your medical alert device to work.

Medical Guardian also offers more special features than Life Alert, including the following:

  • Smartwatch device
  • Location tracking (meaning caregivers or loved ones can use the Medical Guardian app to pinpoint your location if you need help)
  • Medication reminders
  • Automatic fall detection

One downside to Medical Guardian is its battery life compared to Life Alert—Medical Guardian batteries are rechargeable and last a maximum of five days, while Life Alert batteries can last up to 10 years. That’s mainly because the special features in Medical Guardian devices drain more battery than Life Alert’s simpler devices. Medical Guardian’s rechargeable batteries need to be replaced about every two to three years.

Life Alert

Life alert medical alert system


  • Has its own emergency monitoring center and does not contract with outside call centers
  • Devices use long-lasting lithium batteries (last up to 10 years)
  • Monthly fees don’t increase over the term of the contract
  • Been in business for more than 30 years


  • Requires a three-year contract, which you can’t cancel unless the user passes away or family can prove the user is in a 24-hour nursing facility
  • Automatic fall detection is not available
  • No online transparency with pricing 
  • No promotional discounts 
  • Shorter device range (800 feet—about two football fields)
  • Higher starting monthly cost ($50–$90)

You might be familiar with Life Alert’s memorable catchphrase, “Help! I’ve fallen and I can’t get up!” Thanks to this phrase, Life Alert is one of the best known medical alert companies in the U.S. It’s been around for more than 30 years and has very high name recognition.

One of the company’s biggest pros is its long battery life—Life Alert devices are more basic than Medical Guardian’s (they don’t have special features like location tracking or medication reminders), but they last much longer. Life Alert batteries can last up to 10 years, compared to a maximum of five days with Medical Guardian.

Life Alert’s website is cluttered, and the company doesn’t provide its prices online. Our Reviews Team had to contact the company through its toll-free number to answer a series of questions and provide a mailing address so Life Alert could send a brochure with details on plans and costs. After some back and forth over the phone, our team was able to gather pricing information for Life Alert’s three packages: its at-home system; at-home + help button; and at-home + help button + GPS system (this is Life Alert’s only on-the-go system). 

Besides the lack of transparency, one of Life Alert’s biggest downsides is its contract—very few other medical alert companies require people to sign a contract, yet Life Alert requires a three-year contract. Users are only able to get out of the contract early if they die or if a family member can prove they’re receiving 24-hour nursing care. These lengthy and restrictive contractual terms are one of the main reasons our Reviews Team doesn’t recommend Life Alert.

Customer service and payment options

The customer service team at Life Alert is available by phone at 1-800-338-9090 Monday through Saturday from 6 a.m. to 7 p.m. PST. 

Life Alert accepts payments in the form of check, credit card, or check by phone.

Please keep in mind that because it requires a three-year contract, the monthly costs listed below are breakdowns of the full cost.

How do I choose the best medical alert system for me?

Choosing the best medical alert system starts with considering different features, such as at-home vs. on-the-go systems, monitoring assistance, battery life, and fall detection. With numerous medical alert systems and plans to choose from, it can be challenging to know which one is right for you. 

Consider the following key features:

At-home vs. on-the-go systems

At-home systems include a base unit that connects to a monitoring center via landline or cellular service. Users wear a device around the neck or on the wrist, with a built-in button they press to activate the system. The Medical Guardian system has an at-home range of 1,400 feet, while Life Alert’s at-home system has a range of 800 feet.

On-the-go systems use cellular networks and GPS tracking (which rely on satellites to pinpoint your location) to connect users to monitoring center operators wherever they go, as long as they stay within range of the cellular service. With on-the-go systems, there’s no need for a base unit.

To learn more on medical alert monitoring centers, read about how medical alert systems work.

Monitoring assistance

One benefit of having a monitored medical alert system is the 24/7 monitoring, which both Life Alert and Medical Guardian offer. The Monitoring Association (TMA) has designated both companies as TMA Five Diamond certified, meaning they adhere to random inspections and quality control criteria.

Fall detection

Fall detection (also called automatic fall detection) uses sensors such as accelerometers, which detect motion, to identify when you fall and alert the medical alert company’s monitoring center that you need help. It’s a popular function—respondents to our Reviews Team’s survey chose it as the most desired special feature in a medical alert system.

Nearly every company includes a disclaimer on its website stating no device is 100% accurate, so many fall detection devices include a help button as well in case the device doesn’t record your fall.

Fall detection uses a wearable device (typically a necklace) to detect when the wearer falls and automatically send help. Some medical alert smartwatches also have a fall detection option, but experts generally agree the best way to wear a fall detection device is as a necklace high on your chest and on top of your sternum for accuracy. Research from 2016 shows fall detection worn around your neck is more accurate than fall detection worn around your wrist.1

And according to the Centers for Disease Control and Prevention, around 36 million older adults fall every year.2 Of those who fall, 3 million are injured seriously enough to need emergency care, and their chances of falling again are doubled. Fear of falling is actually one of the top causes of falling. In a study published by BMC Geriatrics in June 2021, researchers noted “fear of falling and previous falls are both risk factors that affect daily activities.3” Fear of falling leads many older adults to limit physical activities like cleaning their home, going outside, and even eating. In turn, limiting those activities can then increase fall risk.

Fall detection can alert emergency operators more quickly, save precious time, and give users peace of mind. Medical Guardian offers fall detection technology, while Life Alert does not.

Battery life

In a power outage, both Life Alert and Medical Guardian have at-home base units with backup batteries. You don’t need to charge Life Alert’s on-the-go necklaces (which can last up to 10 years), while you’ll need to recharge Medical Guardian’s batteries every 1–5 days, depending on the device.

Having a longer battery life may be helpful for those who routinely forget to charge devices or have memory impairment.

Life Alert vs Medical Guardian: Bottom Line

Although Life Alert is a well-known company, our Reviews Team doesn’t recommend Life Alert’s medical alert systems due to the company’s restrictive contracts and reluctance to provide transparent pricing. More than 25% of Life Alert users surveyed by our Reviews Team reported their contract was misleading.

Our Reviews Team chose Medical Guardian as the better option because you can easily find its pricing structure on its website, there is no long-term contract requirement, its plans can be canceled any time, its prices are lower, and its devices come with more options and special features.
