Safety Is A Property Of The Shift, Not A Separate Panic App
Timed safety check-ins and a one-tap SOS on the app frontline staff already use — a tiered escalation engine climbs a responder roster until a human acknowledges. No extra device, no second login.
What Lone Worker Does
Timed Safety Check-Ins
Per-site or per-team check-in schedules with a configurable interval and grace window — defaults are 60-minute intervals with a 10-minute grace. Workers tap "I'm safe"; overdue check-ins are detected in SQL and open an alert.
One-Tap SOS
Trigger an SOS from web or API. Location is captured ONLY at trigger time — no continuous GPS tracking — and the capture is gated by a per-business setting. It is not a 911/PSAP dialer; it routes to your own responders.
Tiered Escalation Engine
An alert climbs a dynamic-depth roster ladder — each tier has its own channels and acknowledgement timeout (default 120 seconds). States move raised → notifying → acknowledged → resolved, plus a terminal exhausted.
First-Ack-Wins Ownership
Acknowledgement is row-locked and first-ack-wins — climbing stops the moment a responder takes ownership. A worker cannot acknowledge their own alert; the alert is owned, never just sent.
Dead-Man's Switch
If the ladder is exhausted with no acknowledgement, the alert broadcasts to ALL safety admins on push, email, SMS, and voice. It is not tenant-disableable — the one guarantee an admin cannot turn off.
Immutable Audit Trail
Every state change, notification, acknowledgement, and resolution writes an append-only alert event. The trail is immutable and CSV-exportable — ready for an insurer, a regulator, or a union safety committee.
Two Guarantees A Standalone Panic App Cannot Make
No Silent Terminal State
Most "panic button" apps fire a notification and hope someone sees it. Lone Worker's engine guarantees every alert ends in one of two loud outcomes — resolved by a responder, or exhausted into a non-suppressible broadcast to safety admins. There is no quiet failure mode where an alert sent to an off-shift phone simply disappears.
- States are explicit — raised → notifying → acknowledged → resolved, plus terminal exhausted.
- Exhaustion is loud — push, email, SMS, AND voice to every safety admin.
- Not disableable — the dead-man's switch is deliberately not a tenant toggle.
- Every transition logged — the audit trail proves the alert was never silently dropped.
Mandatory Human Ownership
A notification is not a response. Lone Worker keeps climbing the responder roster every ~60–120 seconds — push, then SMS, then voice, tier by tier — until a real human acknowledges. The actionable "I've got this" action stops the climb and records who owns it, row-locked so two responders can't both claim it.
- Climbs until acknowledged — each tier's ack timeout defaults to 120 seconds.
- First-ack-wins — row-locked so a concurrent tick can't double-notify a claimed alert.
- Self-ack blocked — a worker cannot acknowledge their own alert.
- Actionable push — responders tap "I've got this" straight from the notification.
Lone Worker In Practice
A practical scope check: what the app covers, which controls matter, and the workflows teams usually run first.
Core workflow
A missed check-in or a one-tap SOS opens an alert that climbs a site/team responder roster via push, SMS, and voice until a human acknowledges.
Controls that matter
Configurable per business: check-in interval and grace window, per-tier acknowledgement timeout, whether SOS captures location, and whether a resolved incident opens a Safety Hub record.
Scope and specs
Useful specs: 4 channels (in-app/push, SMS, voice, email); default 60-min check-in interval / 10-min grace; default 120-second per-tier ack timeout; 7 tables; immutable append-only audit trail.
Lone late-shift cleaner
A solo cleaner on a covered shift gets a check-in prompt every hour. Miss one past the grace window and an alert climbs the roster until a supervisor acknowledges.
Field technician SOS
A tech in a remote plant room taps SOS. Location is captured at that moment, responders are paged tier by tier, and the first to acknowledge can open a Live Assist video channel.
After-hours desk with nobody home
An overnight alert climbs every tier and nobody answers. Instead of vanishing, it exhausts into a dead-man's broadcast to all safety admins on four channels.
Connected To The Rest Of MangoApps
→ Shifts & Scheduling
Lone Worker reads who is on, when, and where from Shifts & Scheduling — check-ins and SOS routing are scoped to the worker's covered shift, not a separate roster you maintain by hand.
See Shifts & Scheduling→ Safety Hub
Resolving an alert as an incident hands off to Safety Hub — a real Incident record opens with the worker, shift, location, and the originating alert linked, so the investigation lives where EHS already works.
See Safety Hub→ Live Assist
On acknowledgement, an optional Live Assist video channel opens between the worker and the responder — the worker shares their POV while help is on the way. Off by default; one toggle to enable.
See Live Assist→ Broadcasts & Alerts
Lone Worker rides the same notification channels the platform already runs — push, SMS, voice, and email — honoring per-user settings and business gating without a separate paging vendor.
See Broadcasts→ Time Clock & Attendance
Alerts tie back to the attendance record for the shift, so the evidence chain links the safety event to who was actually clocked in at the time.
See Time Clock→ Ask AI
The Lone Worker AI agent answers safety-ops questions from the Ask AI sidebar — who's at risk right now, an alert's timeline, your own check-in status — grounded in live alert data.

REPLACES POINT TOOLS
One lone-worker safety layer in place of a hardware panic vendor
Most lone-worker programs run a separate device or app, a separate monitoring contract, and a separate audit export — none of which know the worker's shift, location, or org chart. Lone Worker folds the whole loop into the app frontline staff already carry.
StaySafe
Lone-worker app + monitoring hub
- Runs on the branded app workers already use for shifts and pay — no second app to install, keep logged in, and remember to open
- Escalation climbs your own responder roster tier by tier, not just a generic monitoring inbox — every climb and acknowledgement is in the audit trail
- Resolving an alert as an incident opens a real Safety Hub record — the investigation lives in the same platform, not a separate export
SoloProtect
Dedicated lone-worker safety device
- No extra hardware to buy, charge, distribute, and replace — the SOS is one tap in software on the phone the worker already carries
- Roster, sites, and shifts come from the live platform — no parallel device directory drifting every time someone changes teams
- Per-tier acknowledgement timeouts and channels are admin-configurable, not fixed to a device vendor's monitoring SLA
Blackline Safety
Connected safety wearables + monitoring
- Software-first — no wearable fleet to provision; deploy by turning the app on for the shifts that need it
- Location is captured at SOS trigger time only, not continuously streamed — a privacy posture frontline workers actually accept
- The dead-man's switch is built in and non-disableable — exhaustion always broadcasts to safety admins on four channels
AlertMedia (lone-worker)
Mass-notification suite with a lone-worker add-on
- Lone-worker safety is native to the workforce platform, not a bolt-on to a mass-notification tool — it knows the shift, the site, and the responder roster
- One per-employee license covers the safety loop alongside shifts, time clock, and Safety Hub — not a separate notification contract priced per message
- First-ack-wins ownership with a row-locked acknowledge — an alert is owned by a named responder, not just blasted to a distribution list
PLATFORM ADVANTAGE
Lone Worker inherits everything else MangoApps already does
A point lone-worker vendor has to build, buy, or integrate each of these. Lone Worker gets them for free because the platform already runs them.
Identity & SSO
Inherits your SAML/OIDC SSO, MFA, and SCIM provisioning. A worker checks in or taps SOS with the same login they used to clock in — no separate device PIN.
Shift-aware routing
Who's on, when, and where comes from Shifts & Scheduling — check-ins and escalation are scoped to the covered shift, not a hand-maintained roster.
Mobile app already in hand
Check-ins and SOS live in the branded app employees already use — no hardware to provision, charge, or replace, and nothing extra to carry.
Notification channels
Push, SMS, voice, and email run through the same notification engine the rest of the platform uses, honoring per-user settings and business gating.
Audit log & retention
Every alert event lands in an immutable, append-only trail with the same retention posture Legal and Compliance already rely on — CSV-exportable.
Translation in 100+ languages
Check-in prompts and alert messages translate inline using the same engine that powers Chat, SOPs, and Policy Hub — for a multilingual frontline.
INDUSTRY FIT
Built for the workplaces where someone is working alone
Lone Worker fits any employer with solo or remote shifts, but it earns its keep where a missed check-in is the difference between a quick response and a worst-case outcome.
Facilities & Cleaning
Solo overnight cleaners and maintenance staff get hourly check-ins and a one-tap SOS — alerts climb to the on-call supervisor before anyone notices a phone went unanswered.
Field Service & Utilities
Technicians in remote plant rooms, substations, and customer sites trigger SOS with location captured at that moment — no continuous tracking, full responder escalation.
Healthcare & Home Visits
Community nurses and home-care workers on solo visits check in on a schedule; a missed check-in pages the coordinator team tier by tier.
Retail & Convenience
Lone closers and overnight clerks get a discreet SOS and a guaranteed escalation that reaches a manager — not a panic alarm that nobody is watching.
Logistics & Warehousing
Drivers and yard staff working off-hours check in between stops; SOS ties the alert to the shift and attendance record for the evidence chain.
Construction & Property
Lone site inspectors and after-hours security get check-ins scoped to the jobsite, with escalation routed to the responder roster for that location.
WHY MANGOAPPS WINS
One platform beats a hardware panic vendor on every axis
The argument safety, ops, HR, and finance all share — and the one a standalone lone-worker device structurally cannot answer.
Cheaper than the device
One per-employee suite license covers the safety loop alongside shifts and time clock — no wearable fleet, no per-message monitoring contract, no device replacement cycle.
More secure
One identity perimeter, one audit log, one retention policy across every alert. Nothing for security to re-certify when you turn safety on.
Easier to deploy
Already deployed if you have MangoApps. Turn the app on, set a check-in cadence and a responder roster, and the first SOS routes the same day.
Easier to use
Workers check in and trigger SOS from the same app they use for their shift and pay — no second device, PIN, or login under stress.
Easier to manage
Sites, shifts, and rosters come from the live platform — safety admins configure cadence and escalation, not a parallel device directory.
Two enforced guarantees
No silent terminal state and mandatory human ownership are engine-enforced — not best-effort settings a vendor can quietly let fail.
AI is actually better
Lone Worker AI answers "who's at risk right now" from live alert data, governed by the same permission model — its one write, acknowledge, is confirmation-gated.

Frequently Asked Questions
No — and that's deliberate. Man-down and fall detection are sensor-dependent and unreliable on a general-purpose phone, so they are intentionally not implemented. Lone Worker is built on timed check-ins and a one-tap SOS, both of which work on the device every worker already carries.
No on both. SOS is not a 911/PSAP auto-dialer — it routes to your own responder roster. And there is no continuous GPS tracking; location is captured only at the moment SOS is triggered, and only when the per-business "capture location" setting is on.
It can never silently disappear. The alert climbs every responder tier, and if the ladder is exhausted with no acknowledgement it fires the dead-man's switch — a broadcast to all safety admins on push, email, SMS, and voice. That broadcast is not tenant-disableable.
An alert climbs a dynamic-depth responder roster. Each tier has its own channels and an acknowledgement timeout (default 120 seconds). If no one acknowledges within the timeout, the engine advances to the next tier. The first responder to acknowledge wins — climbing stops, row-locked so two responders can't both claim it — and a worker cannot acknowledge their own alert.
Three background jobs run on the attendance queue — a scheduler arms check-ins every 5 minutes, a missed-check-in detector runs every minute, and the escalation driver advances overdue alerts every minute. Sample-data tenants are skipped and disabled tenants are a no-op.
Yes. Every state change, notification, acknowledgement, and resolution is written to an immutable, append-only alert-event log, and that trail is CSV-exportable — ready for an insurer, a regulator, or a safety committee.
It answers safety-ops questions from the Ask AI sidebar — who's at risk right now, an alert's escalation timeline and outcome, your own check-in or SOS status, and responder-roster coverage. Six tools in all; its single write, acknowledging an alert on your behalf, is confirmation-gated.
