The log

Every dive, kept properly.

A logbook that does the dive justice: the depth profile drawn as a clean trace, with your gas, kit and buddies beside it, all readable at a glance. Never a spreadsheet.

A dive in the log. Blue Hole, Gozo: the recorded depth profile with temperature, gas and ppO₂ tracks, max and average depth

The record

More than a depth and a time.

Drag the profile to inspect any moment of the dive. Temperature, tank pressure and ppO₂ ride alongside the trace, told apart by weight, dash and label rather than colour alone. Underneath sits everything else that made the dive: the mix, the rig, the buddies, the conditions, the photos.

  • Air, nitrox and trimix, with start and end pressures per cylinder
  • Up to eight photos a dive, straight from your camera roll
  • Buddies, site, water type, visibility, weights, suit, notes, rating. Chips, not free text
The logbook: a list of dives, each with its own profile trace, rating and stats

Sites, mapped and remembered.

Every dive pinned on a world map that works offline, and a site book that keeps count: how often you’ve been down, and how long you stayed.
