Real-Time Data on Any Device
A cloud-based roll call that shows the same live picture on every modern iOS and Android phone, tablet and specialist device.
Musterd is cloud-based, so the roll call is live wherever you open it. Fire marshals, wardens and incident managers all see who is on site, who is safe and who is still missing, updating as it happens.
Presence data comes from your access control system and is synchronised across every device in real time, so nobody works from an out-of-date printout, and a warden can pick up a spare device at a muster point and carry on.

What Real-Time Data on Any Device does for you
One live roll call, on every device
Every check-in, badge scan and status change appears on every marshal’s device as it happens. Wardens at different muster points work from the same, up-to-date list, so nobody is missed because a list was out of date.
Uses the devices you already have
Musterd runs on modern iOS and Android smartphones and tablets, and on specialist rugged devices for harsh environments. Keep spare devices at muster points for redundancy: whichever one a marshal picks up shows the same live data.
Presence data, kept up to date for you
Musterd connects to your access control, HR and visitor management systems, and to RotaOne, so the roll call starts from who has actually badged in today. There is no list to type up, and new starters and leavers are kept up to date automatically.
