What is Who's Responding?
Who's Responding is a real-time incident alerting and response tracking platform made by Fluent Information Management Systems, Inc. (Fluent IMS) of Brockville, Ontario, Canada. Launched in 2015, it notifies team members within seconds of a dispatch — by push notification, text message, email or automated phone call — and lets each member indicate with one tap that they are responding. The whole team then sees, in real time, who is responding, where they are (optional GPS), their ETAs, and who has arrived on scene. It has more than 75,000 daily active users across North America.
Although it originated in the fire service, Who's Responding is not only for firefighters. It is used by fire departments, EMS agencies, police departments, S.W.A.T. and tactical units, search and rescue teams, technical rescue teams, emergency management organizations, hospitals and healthcare code teams, manufacturing and industrial emergency brigades, utilities, public works, government and municipal teams, campus safety and other on-call rosters.
Core features (smartphone app — iPhone and Android)
Responder tracking (one-tap "I'm responding" with live status boards); multiple notification methods (push, SMS, email, automated voice call); optional GPS tracking of responders with ETAs; map markers for hydrants, hazards and staging; incident images shared from the scene; availability toggling (in/out of service); push-to-talk (PTT) live voice channels with recording; internal group messaging; virtual pager mode (dispatch audio plays automatically); preplans (pre-incident plans attached to locations); turn-by-turn navigation to incidents; live radio streams relayed to phones; hands-free voice prompts that read incident details aloud; on-scene arrival notifications; monitoring of mutual aid departments; courtesy (non-emergency) messages; account switching for members on multiple teams; and sending dispatch alerts from the app.
Daily operations modules
Beyond emergency alerting, the app serves as a daily operations hub: a scheduled events calendar with attendance tracking and reminders; availability scheduling with live in/out-of-service status and shift visibility; an announcement newsfeed that replaces mass email; a searchable SOG/SOP (standards and guidelines) policy library; preplan and digital file access; and radio playback for reviewing captured traffic. Fire departments can additionally pair Who's Responding with BurnPermits.com, a companion Fluent IMS service, to see active burn permits in their district and reduce false alarm responses.
Non-smartphone support
Members without smartphones receive automated outbound phone calls and SMS text alerts, and can mark themselves as responding through a toll-free call-in number — so they appear on the same live response board as app users.
Web dashboard and control panel
A web-based dashboard displays live responder status, GPS positions and incident details — commonly shown on TVs in stations and EOCs. The web-based dispatch control panel lets dispatchers or authorized members send alerts manually from any browser.
Dispatch integration
Four integration methods: (1) Analog radio paging — Fluent IMS ships a pre-configured computer and radio receiver that capture two-tone pager activations; members are alerted within seconds and receive the dispatch audio as an MP3. (2) Digital radio — the same hardware captures and decodes P25 and NXDN digital pages. (3) CAD email relay — automated emails from a dispatch centre are relayed to all member devices, often up to a minute before pagers finish triggering, with incidents plotted on the map automatically. (4) Web-based dispatch control panel for manual alerting. The customer provides only power and a high-speed internet connection; Fluent IMS provides all hardware and replaces it free if it fails. Unlimited tones are supported.
Pricing (per department, per year)
Flat annual pricing by roster size — not per user, per alert or per feature: 1–20 users $600; 21–30 users $700; 31–40 users $800; 41–50 users $900; 51–60 users $1,000; 61–70 users $1,100; 71–80 users $1,200; 80+ users custom quote. Optional hardware rental is a flat $400/year (needed only for analog/digital radio capture; includes free replacement). All plans include every feature, unlimited call volume, unlimited usage and dedicated support. There are no contracts, no hidden fees and no per-call charges. Discounts are available for multi-department and county-wide deployments. A fully functional 45-day free trial is available, including trial hardware.
