SARnotes

Built by Search and Rescue crews, SARnotes turns your phone into an operational log book. Press and hold to record a voice note and it's instantly tagged with your GPS position, an accurate timestamp, and an optional photo, then plotted on a map to build a complete, chronological record of your operation.

Made for people who carry operational responsibility: SAR teams, coastguard, vessel masters, skippers, and incident commanders. SARnotes lets you record your decisions and the reasoning behind them as they happen, for playback, handover, and after-action review.
