Personal alarms, careline pendants and check-in apps: what each is actually for

If you've started looking into "what helps keep Mum safer at home", you've probably already met half a dozen overlapping things: pendant alarms, fall detectors, careline schemes, smart speakers, check-in apps, GPS trackers, the lot. They mostly look like they do the same thing, they don't. This piece is the plain-English breakdown.

The categories

Roughly, there are five things in this space, and they answer different questions.

1. Pendant alarms (also called personal alarms / careline pendants). Push a button, get a 24-hour response centre on the line through a base unit at home. They will speak to your parent, and if there's no response, send help.
2. Fall detectors. Same idea but with sensors that detect a fall automatically. Useful if your parent is unconscious or unable to press the button.
3. GPS-tracked alarms. Pendants that work outside the home, with location. For people who go out and might wander, particularly relevant in some forms of dementia.
4. Smart-home detectors. Cooker, smoke, water-leak, door-open monitors. Less about "they fell" and more about "the cooker has been on for three hours".
5. Check-in apps (like Getwello). A daily one-tap "I'm well" from your parent to the family. Less about emergencies, more about everyday reassurance.

You'll see why these aren't interchangeable.

What a pendant alarm is for

Pendant alarms are designed for the specific moment when something has gone wrong and your parent is alive but in trouble. The classic case is a fall in the home where they can't get up but can press a button.

How it works in practice (UK):

• A base unit sits on a hall table or by the bed, plugged into the mains and the phone line (or 4G).
• Your parent wears a pendant or wristband. Press it and the base unit dials a 24-hour response centre.
• The centre tries to talk to your parent through the base unit's speakerphone. If they can't, the centre sends help, usually a key holder you've nominated, otherwise an ambulance.

This is the most common form of telecare in the UK, and for many older people it's exactly the right tool. Age UK has a clear guide to choosing one.

What a pendant alarm is not for: knowing your parent is OK day-to-day. The pendant tells you only when something goes wrong. The rest of the time, you don't hear anything.

What a fall detector adds

The biggest weakness of a pendant is that the wearer has to press it. A fall that knocks them out, or that puts them somewhere they can't reach the button, doesn't get detected.

Fall detectors fix that. They're a bit pricier and they have false positives (people drop the pendant and the alarm goes off). For frail people, or anyone who's already had a fall they couldn't get up from, they're often worth it. For active 70-year-olds, often overkill.

What a check-in app is for

Pendants and detectors deal with crises. Check-in apps deal with the much more common problem: how does the family know, day to day, that everything's normal?

The pattern is simple. Your parent taps one button each morning to say "I'm well". The family gets a quiet ping. If they don't tap by their usual window, the app reminds them gently. If they still haven't tapped, the family is told.

This isn't an emergency tool. It's a sustainable everyday tool. It replaces the daily phone call you'd otherwise feel like you should make. It picks up the slow stuff a pendant can't see, the day where Mum stayed in bed because she felt off, didn't fall, but was quiet for 18 hours.

(For more on what makes one of these usable for older users, see what makes a daily check-in app actually usable for older parents.)

The honest comparison

Here's the differences laid out plainly.

For…	Pendant alarm	Check-in app
A fall they can't recover from	Yes, this is the use case	No
A fall where they're conscious	Yes (if they press)	No
Knowing they're OK each morning	No	Yes, this is the use case
A bad week where they've stayed in bed	No	Yes (no check-ins → family notified)
Out and about emergencies	Only with GPS pendant	No
Coordinating siblings on visits	No	Yes (Getwello has a shared calendar)
Cost	~£4 to £20/month UK	~£5/month UK (Getwello)

What we'd recommend

For most UK families with a parent at home:

• If the parent is at any risk of falls, get a pendant alarm. Even a basic one. It's cheap insurance and the response centres are good.
• Consider a fall detector if they've already had a fall, are very frail, or are at higher fall risk.
• Add a daily check-in app on top for everyday reassurance. The check-in app prevents the slow problems; the pendant prevents the catastrophic ones.
• If they've had a major life event (stroke, dementia diagnosis, recent bereavement), talk to your local council's adult social care team about telecare options that fit. Often subsidised or free.

The two worst options are: assume the pendant is enough (it isn't, for everyday reassurance) or assume the app is enough (it isn't, for falls). They cover different problems. Most families use both, and the total cost is still less than a single hour of paid care a week.

If you only buy one thing

If you can only do one, and your parent is medically stable and not at high fall risk, start with the daily check-in. It's the one most families use every single day; pendants get used rarely (when they work, they save lives, but day-to-day they're invisible).

If your parent is medically frail or has had a fall, flip the order: pendant first.

Where Getwello fits

Getwello is the check-in app side of this, daily one-button check-in from your parent, plus the shared visit calendar for the family. We don't do pendants. We work alongside one fine. See how it works, or read the broader guide if you're at the start of this.
