For use with Noggin's OCA software for crisis communication and incident management. Create, edit or view events, logs, reports, assets, contacts, tasks and documents, as well as send and receive messages, and activate workflows. Includes GPS location tracking, and the easy capture and submission of geo-coded photo, video and audio content using the device camera, GPS and microphone, straight back to your OCA. Supports offline use without an internet connection - you can view records or documents previously viewed or synchronised, or even create events, logs, reports or other records to be automatically forwarded when a connection is available. The app requires a Noggin OCA system administrator to send you a 'Contact Identifier' so that OCA knows who you are, and which OCA system to link your app to. Continued use of GPS running in the background can dramatically decrease battery life.

Verdict
The clearest difference is update cadence: C3 Mobile at fortnightly against OCA's every 2 months. C3 Mobile also leads on iOS requirement (6.1 vs 11.0). On price, ads, in-app purchases and device support there is nothing between them.
