Appello's Android app on a phone: a responder's job list

When someone needs help, the responders nearest to them have to know at once, act with one hand and keep each other informed. Our lead designed the app end to end, working with the product manager and engineer, inside a tight deadline.

Designed for the field.

Locate, respond, report: the few actions that matter under pressure come first, in large targets and clear states, and everything else gets out of the way.
