Read full description

emsOS is the mobile app for volunteer and career EMS agencies. It puts the things your crew needs every shift in one place, using your agency's own portal and data. Sign in with your agency's code and your portal account. Your agency sets up what you see, so you only get the features it has turned on. HOME A quick dashboard when you open the app: what needs your attention, your tasks, which rigs are in service, shortcuts to your most-used screens, and what's coming up on the calendar. RIGS AND VEHICLES - Rig Status shows every rig's current status at a glance. - Rig and station checklists can be filled out right on your phone, even with a weak signal. Your answers are saved and sent when you're back online. - Vehicles shows each vehicle's details, expiration dates, mileage and history. - Vehicle Problems lets you report an issue by describing it or filling in a form, add photos, and follow it until it's fixed. SUPPLY Find items, restock a rig, check alerts for low stock and expirations, and receive deliveries by scanning barcodes. REFERENCE - Protocols: your agency's protocol book, searchable by number or keyword and saved on your phone for use offline. - Hospitals: your agency's list of hospitals, including door codes, also saved for offline use. - Phone Numbers: your agency's important contacts. - Documents: your agency's bylaws, forms and other files. - Ask AI: ask questions about your agency's own documents and get answers with citations. - Contractions Timer: a simple tap-to-time tool. ALL IN ONE ORGANIZATION - Calendar: see training, meetings and special events. Authorized members can add and edit events. - Tasks: see what's assigned to you, create tasks, add photos and comments, and follow progress. - Member Directory: find and contact fellow members. - Meetings: check in with a room code or QR code and vote when your chair opens a vote. - Expense Reports: snap a receipt, create a report and submit it. - My Profile: update your information and photo, and sign out of devices you no longer use. BUILT FOR MULTIPLE AGENCIES If you volunteer with more than one agency, you can stay signed in to each and switch between them. IMPORTANT emsOS is for members of participating agencies. You need an agency code and an account from your agency to sign in. Ask your agency's officers if you don't have one. The app displays the protocols and reference information your agency provides. It does not replace your agency's medical direction, training or official procedures.
