ToneLogger is the activity log built for volunteer Fire and EMS departments. Record runs, training, and station details in seconds, respond to dispatches with live location, track who turned out, sign incident reports, and see your participation at a glance. Made for responders: • Log calls, training, and details right from your phone • Respond to a dispatch in one tap — share your live location so your crew sees who's rolling and their drive-time ETA on a live incident map • Choose how loudly dispatches reach you for each availability state — loud alerts break through Focus • Track participation and apparatus per activity • Sign incident reports — NERIS-ready for the new federal fire reporting standard • Put a live incident board on a station wall-mounted TV • Review your recent calls and personal reports • Serve more than one department? Switch between them in a tap • Officers and admins: approve members, manage onboarding, see live responders on a map, and get push notifications when something needs you ToneLogger is a record-keeping tool — not a 911 dispatch system and not a medical device. Don't rely on it for emergency response, and don't enter patient health information. Your location is shared with your department only while you're actively responding to a call. Sign in with your work email, Apple, or Google — no password to remember. Your department admin grants access to its records. Questions? https://tonelogger.com/help
