What you get

One place for the full dive workflow.

Planning, exploring, logging, and community, all connected to one account.

Dive Planning & Tables

Plan repetitive dives on SSI or PADI tables with Air or Nitrox. Trace NDL, pressure groups, and residual nitrogen, with MOD, EAD, reverse-profile, and surface-interval checks.

Dive Site Explorer

Search mapped dive sites and shops, and filter by type, maximum depth, or required certification. Keep saved sites and personal locations.

Logbook & Profile

Save plans and log completed dives, with totals for dive count, bottom time, and depth. Keep certifications, saved sites, and photos on one profile.

Dive concepts explained.

The key metrics the planner calculates, in plain language.

NDL — No-Decompression Limit

The maximum time you can stay at a depth without requiring decompression stops on the way up.

MOD — Maximum Operating Depth

The deepest safe depth for your gas mix, based on your chosen oxygen partial-pressure (PPO₂) limit.

EAD — Equivalent Air Depth

The air depth a nitrox mix behaves like, used to look up the correct table row for the dive.

Pressure Group

A letter (A–Z) representing how much residual nitrogen your body holds after a dive.

RNT — Residual Nitrogen Time

A time penalty added to a repetitive dive to account for nitrogen left over from the previous dive.

Surface-Interval Credit

Nitrogen you off-gas while resting on the surface, which lowers your pressure group before the next dive.
