The dive log

Every dive,
kept properly.

A logbook that does the dive justice — readable at a glance, never a spreadsheet. The depth profile as a clean trace, your gas, kit and buddies, photos and notes, all in one place.

The profile

The dive, as a clean trace.

The depth profile is the hero of every dive — given room, drawn as an instrument would draw it. Temperature and tank pressure ride alongside, distinguished by weight and label rather than colour alone, so it reads the same to every diver.

  • Depth, temperature and tank pressure on one trace
  • Safety-stop and ascent markers called out on the line
  • Big tabular numerals — never a shifting, ragged column

The detail

Everything about the dive, in its place.

A dive is more than a depth and a time. ScubaOS keeps the full record — what you breathed, what you wore, who you dived with, and what you saw — without ever feeling like data entry.

Photos & video

Straight from your camera roll, attached to the dive — and stitched into the share card later.

Gas & kit

The exact mix, cylinder and rig you dived — EAN32, trimix, a stage or two — logged as chips, not free text.

Buddies & sites

Tag the divers you were with and the site you dived. Conditions, visibility, current and notes round it out.
