Medical alert system or check-in app? How to choose
A medical alert system and a daily check-in app solve different problems. A medical alert system is for emergencies: your parent presses a button, or a sensor detects a fall, and a 24/7 monitoring center responds. A check-in app is for the quiet days: your parent confirms they’re okay at set times, and family is alerted when that signal doesn’t come. If falls or sudden health problems are a real risk, start with a medical alert system. If your parent is independent but lives alone, a check-in app may be all they need. Many families use both.
What a medical alert system does
A medical alert system, also called a personal emergency response system (PERS), is a button worn as a pendant or wristband. Pressing it connects your parent, through a base unit at home or a mobile device with GPS, to a monitoring center that answers around the clock. The operator talks to them, then calls family or sends emergency services as needed. Many systems offer automatic fall detection for an extra monthly fee.
Some devices skip the monitoring center: the button calls a short list of family contacts one after another and dials 911 only if nobody answers. These usually cost a one-time price instead of a monthly fee, but nobody trained is on the other end (The Senior List).
What a daily check-in app does
A check-in app works the other way around. Instead of waiting for a call for help, it waits for a sign that all is well. With Heyimokay, your parent picks two windows a day, for example 8–10 am and 6–8 pm, and taps one “I’m okay” button during each. If a window closes without a check-in, Heyimokay sends a text message and an email to up to six people they’ve chosen, so the nearest one can call or stop by.
It’s built for the day something goes wrong and nobody would otherwise notice: a fall when the pendant is on the nightstand, an illness that keeps them in bed, a phone that has gone quiet.

| What your parent does | Wears the button and presses it when they need help | Taps “I’m okay” twice a day |
| Who responds | A 24/7 monitoring center, then family or 911 | Up to six family members, friends or neighbors |
| How fast | Within moments of pressing the button | When a check-in window closes |
| Fall detection | Optional on many systems, for an extra fee | No |
| Location | GPS on mobile systems | Not used |
| What you need | The device and a monitoring plan | An Android phone |
| Cost | Usually a monthly fee, plus equipment | Free |
What a medical alert system costs
- Monitoring: most systems cost about $25 to $65 a month for professional monitoring (The Senior List, 2026).
- Equipment: a one-time fee from nothing to about $200, depending on the provider and the device. Mobile and smartwatch-style devices usually cost more.
- Fall detection: typically about $8 to $15 extra a month (NCOA).
- Insurance: Original Medicare doesn’t cover medical alert systems. Some Medicare Advantage plans and PACE programs do, fully or in part, so check your parent’s plan (Healthline).
Prices change often, so confirm current fees and contract terms with each provider. Many review sites earn commissions from the providers they rank.
The gap each one leaves
A medical alert system only helps if it’s worn and used. A pendant left on the nightstand can’t be pressed, and some people hesitate to press the button because they don’t want to make a fuss. Fall detection covers part of that gap, but no fall detection device is 100% accurate: slow, sliding falls are harder to detect than sudden ones (The Senior List).
A check-in app doesn’t respond in real time. It notices a problem when a check-in window closes, not the moment it happens, and it relies on someone in the circle seeing the alert and acting on it. It isn’t an emergency service and doesn’t detect falls.
That’s why the two work well together: the medical alert system covers the moment your parent can call for help; the check-in app covers the day they can’t, or don’t.
Which one does your parent need?
- A medical alert system if they’ve fallen before, are unsteady on their feet, have a condition that can cause a sudden emergency, or are becoming forgetful. Ask their doctor too.
- A check-in app if they’re independent and healthy but live alone, and the worry is that a bad day could go unnoticed. It also suits people who won’t wear a pendant, or who don’t want anything that feels like monitoring.
- Both if there’s a real risk of emergencies and you also want a daily reassurance that doesn’t depend on them pressing a button.
Questions to ask before you buy a medical alert system
- What is the total monthly cost, including fall detection and any extras?
- Are there equipment, activation or cancellation fees, or a long contract?
- Does it work only at home, or everywhere with GPS?
- Can it be worn in the shower, and how long does the battery last?
- Who does the monitoring center call, in what order, and when does it call 911?
- Does your parent’s Medicare Advantage plan help pay for it?
Where Heyimokay fits
Heyimokay is a free Android app for the daily part of the picture: two check-ins a day, and a text message and email to up to six people when one is missed. It doesn’t replace a medical alert system for someone at risk of falls, and it works alongside one. See how it works, or read our guide on how to check on an elderly parent who lives alone.
