About CallSide

CallSide was built out of frustration with how EMS agencies manage their most critical documents. Protocols live in binders that go out of date. PDFs get emailed around and nobody knows which version is current. Providers dig through stacks of paper during active patient care.

We built CallSide to fix this. It's a simple, fast, and reliable system that lets agencies create and publish protocols through a clean web editor, and gives providers instant access through a free mobile app — even without internet.

Built by EMS, for EMS

CallSide is built by people who work in emergency services. We understand that protocols need to be found in seconds, not minutes. We understand that your providers work in areas without cell service. We understand that the software needs to get out of the way and just work.

That's why we built CallSide to be offline-first, search-first, and as simple as possible. No enterprise complexity, no unnecessary features, no friction.

Our approach

• Simple over clever. Every feature earns its place by being genuinely useful in the field.
• Offline-first.If it doesn't work without internet, it doesn't work for EMS.
• Security matters. Agency protocols are sensitive operational documents. We treat them that way.
• Fair pricing. Per-agency, not per-user. The mobile app is free for every provider.
