CPR Guardian Active review
CPR Guardian Active | Personal Alarm with Emergency SOS Button, GPS Location Tracking, 2-Way Voice Calling, Health Monitoring and Reminders (Black, 4G)
By Tom Calder
A capable 4G smartwatch-style alarm with real GPS tracking and two-way calling, but it is family-monitored, not professionally monitored, and its fall detection is explicitly an early-access feature rather than a mature one. Budget for the mandatory SIM plan on top of the device price.
- Best for
- An active older adult who wants an all-in-one wrist alarm with GPS and 4G, and has family willing to monitor alerts via an app rather than pay for a 24/7 call centre.
- Skip it if
- You want a proper 24/7 professionally monitored response service (like Careline365, LifeConnect24…

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- 4G connectivity (future-proof against the 2G/3G switch-off, unlike older pendant alarms)
- Genuine outdoor GPS plus two-way voice calling in one wearable
- Health monitoring (heart rate, blood oxygen, step count) and medication reminders bundled in
Worth knowing
- Fall detection is described by the manufacturer as an early-access feature with adjustable sensitivity, not a finished, fully reliable system — treat it as a bonus, not the reason to buy
- Requires a mandatory monthly SIM/service plan (around £16-20 a month) on top of the purchase price, and it's family/app-monitored rather than a 24/7 professional response service

Who shouldn't buy this
Don't buy this if you want a proper 24/7 professionally monitored response service (like Careline365, LifeConnect24 or your local authority's telecare) — this device alerts family members via an app, not a trained operator, so it only works if someone reliable is watching their phone.

If this isn’t the one

Best for An independent older adult who wants one simple, big-button phone with a one-touch way to ring family — not someone who needs automatic fall alerts.
