Medical alert systems offer seniors a quick and easy way to call for help in case of an emergency. These devices can be installed in the home, in the car, or worn out and about. Their specialized technology ensures that users can communicate with trained emergency personnel with only the click of a button. Choosing the right device with the features that meet your needs can be a challenge. Our side-by-side comparison of major medical alert systems is designed to simplify the process and help seniors decide which system is best for them.

In comparing GreatCall and LifeAlert, we found that both companies have up-front equipment and activation fees, which is uncommon with many of their industry competitors. Despite this, GreatCall has lower monthly monitoring fees and no long-term contracts. Its range of modern offerings, including senior-friendly smartphones, smartwatch-style help buttons and a caregiver tracking app, make it the winner in this comparison.

Our Pick

Although Life Alert is one of the most established medical alert systems, it also has some of the costliest equipment and monthly monitoring fees in the industry. This, paired with its small range of device choices and difficult-to-navigate pricing system brings its competitor, GreatCall, to the winning spot.

GreatCall offers a variety of fully-mobile options for seniors, which include easy-to-use smartphones and medical alert watches that can be connected via Bluetooth. While this company charges equipment and activation fees, it’s far lower priced monthly monitoring plans can save seniors hundreds of dollars a year when compared to Life Alert. While GreatCall is the winner of this comparison, be sure to check out some other major providers for even more affordable options.
