Lone worker app or dedicated device: which is right?
A lone worker app turns a smartphone into a personal safety device. A dedicated device is a separate alarm, such as a button, badge or watch, built for one job. Both raise an alarm, share a location and can detect a fall. The right choice depends on the risk, the work environment and the people. But the real answer is that they are not rivals: app and devices complement each other, and on the right platform they work as one system.
Short answer: choose the app for people who already carry a smartphone and work at low to medium risk. Choose a dedicated device for high risk work, rough environments, or people who cannot or should not rely on a phone. Then connect them on one platform, so an alarm from a device reaches colleagues in the app, and a message from the dashboard reaches every phone and every device.
App and dedicated device compared
| Lone worker app | Dedicated device | |
|---|---|---|
| What it is | A safety app on the phone people already carry | A separate alarm device: button, badge, watch or rugged phone |
| Hardware cost | None: uses existing smartphones | A device per worker |
| Rollout | Invite link, install, log in | Order, configure and hand out devices |
| SOS alarm | On screen, and with hardware buttons or shortcuts on supported phones | One dedicated button, easy to find by touch |
| Man down | Based on phone movement, sensitivity per user | Dedicated sensors, often with tilt, no motion and fall modes |
| Lone worker timer | Yes | Depends on the device |
| Indoor location | With beacons (Pro) | With beacons, on supported devices |
| Messaging and teamwork | Critical messages, assistance requests, team chat (coming soon) | Depends on the device: many show messages on the device, sent over IP and acknowledged, and some support voice |
| Rough environments | Depends on the phone | Built for it: rugged, water resistant, ATEX options |
| Battery | Shares the phone battery | Its own battery, often lasting a full shift or longer |
| Best for | Care, facility services, field staff, bailiffs, office workers who travel | Construction, industry, security, night shifts, high risk sites |
When the app is the right choice
- People already carry a smartphone for work. No extra device to charge, forget or lose.
- The risk is low to medium. Home visits, field service, meetings off site, travel.
- You want to start fast. An invite link is enough; no hardware to order.
- Teamwork matters. Colleagues see who needs help and accept or decline an assistance request, so everyone knows who is on the way.
- You want to design the workflow. Custom views with buttons for fire, aggression or first aid, each starting its own scenario.
When a dedicated device is the right choice
- The work is physical or high risk. Working at height, with machines, in warehouses or at night.
- The environment is rough. Dust, water, cold, or explosive atmospheres that need ATEX equipment.
- A phone is not practical. Gloves, protective clothing, or a company policy against personal phones on site.
- The alarm must be discreet. A small button or badge raises an alarm without anyone noticing.
- Battery life is critical. A device that lasts the whole shift, independent of the phone.
Better together: app and devices as one system
Risk is rarely the same for everyone. A facility company protects its cleaners with the app and gives the engineer who works alone on the roof a tracker. A care organisation uses the app, with a discreet button for the colleague who visits difficult clients.
In most systems that means two worlds: a device platform and an app, each with its own alarms and its own users. Cuebly makes them one. Every app and every device, of every brand, is a member of the same team:
- Alarms flow both ways. When the engineer’s tracker raises a man down alarm, colleagues with the app get it on their phone, see where he is and accept the assistance request. When an app user presses SOS, colleagues with a device get the message on their device.
- Messages reach everyone. Send a message or assistance request from the dashboard, a scenario or the app, to a team, to everyone in a location, or to one person. It arrives on phones and on devices that show messages, where it is acknowledged.
- All brands mixed. A TWIG badge, an Emerit watch, a Teltonika tracker and the app in one team, as if they came from one manufacturer.
And one platform for all of it:
- One dashboard for every alarm, whether it comes from the app or a device.
- The same scenarios for everyone: who is alerted, in which order, and when the alarm receiving centre takes over.
- Mix per person. Give each user the app, a device, or both, and move them up when the risk changes.
- The best of both at once. Pair the Emerit e-B10 Bluetooth button with the Cuebly app: the button raises an alarm, and phone and button warn each other when the connection drops.
- Any device brand. TWIG, Emerit, Teltonika, Eview, Queclink and more.
- Your brand. App, portal and onboarding in your own brand.
Questions to ask before you choose
- What are the real risks per role: aggression, falls, medical, environment?
- Does everyone carry a work smartphone, and may it be used on site?
- Do workers need to raise an alarm without anyone noticing?
- Is the location indoors, outdoors or both?
- Who responds: colleagues, a manager, or a 24/7 alarm receiving centre?
- Will the needs change? Choose a platform that lets you switch per person without starting over.
Frequently asked questions
For low to medium risk work, a good lone worker app is a reliable choice: SOS, man down, a lone worker timer that also runs on the platform, and location. For high risk work or rough environments, a dedicated device is safer. With Cuebly you can combine both.
Yes. The Cuebly app detects man down based on phone movement, with a pre-alarm the user can cancel. Sensitivity and timing are set per user.
The Cuebly lone worker timer runs on the phone and on the platform. If the user does not check in, the platform raises the alarm with the last known location, even when the phone has no signal.
Yes, and that is where they are strongest. In Cuebly the app and dedicated devices of every brand work as one system: an alarm from a device reaches colleagues in the app, and messages from the dashboard reach phones and devices alike. You choose per person.
