A multi-tenant activity and incident log built for volunteer Fire & EMS departments — responders log from a native mobile app, officers manage from a web portal.
Volunteer Fire and EMS departments have to keep careful records: who responded to each call, which apparatus rolled, hours spent on training, and the participation totals that drive pay-per-call accounting and year-end reporting. For most departments that means spreadsheets, paper sign-in sheets, and a lot of manual reconciliation after the fact.
We first solved this for one department with our Town of Canton participation-tracking portal. It worked — and it made one thing obvious: nearly every volunteer department wrestles with the same problem. ToneLogger is that solution turned into a product any department can sign up for.
ToneLogger is a multi-tenant SaaS platform with two front ends over one shared backend. Responders use a native iOS and Android app to log calls, training, and station details in seconds — recording who responded, the apparatus that rolled, and their role on scene. Officers and administrators use a web admin portal to manage the roster, review records, and pull reports.
Because it is multi-tenant, every department gets its own private roster, records, and reporting. Members who serve more than one department can switch between them in a single tap. Sign-in is passwordless — work email magic link, Apple, or Google — and a department admin grants each member access to its records.
True to its name, ToneLogger can also watch a department's dispatch email and turn incoming pages into draft activities automatically, so the run is half-logged before anyone opens the app.
ToneLogger is officially certified NERIS v1 Data Exchange Compatible. NERIS is the federal incident-reporting platform that replaced NFIRS for fire departments in 2026 — and ToneLogger transmits incident reports to it directly. Departments complete their NERIS paperwork right inside ToneLogger, with dispatch details pre-filled, and submit without re-keying data into a separate system.

ToneLogger takes what we learned building a tracker for a single department and turns it into a product any volunteer Fire or EMS department can adopt — no spreadsheets, no end-of-month reconciliation, and a single source of truth for participation and incident records. It is also our answer to the build-vs-buy question we put to every client: sometimes the right move is an existing tool, and now there is one.

ToneLogger might be exactly what you need — or we can build something custom for the way you work.
