Suunto DM5

Suunto DM5 is a desktop application for macOS that lets divers create detailed dive plans, transfer them to compatible Suunto dive computers, and later retrieve dive logs for analysis. After a dive, the software stores each entry in a logbook where users can tag, organize, and compare dives by date, mode, or gear, and view graphical representations of depth, gas consumption, temperature, and other parameters.

The program includes a graphical planner for building dive profiles, managing gas mixes, and generating backup plans, with the ability to export the information to Suunto EON Steel, EON Core, D5, and several other Suunto models. It also supports display customization and firmware updates for those devices. All features are available in multiple languages and the software is free to download.
