## What is Fathom Dive Log?

FATHOM DIVE LOG - YOUR PERSONAL DIVE JOURNAL

A focused, offline-first logbook for scuba divers. Record every dive and watch your underwater history unfold across years.

RECORD
Log the essentials — dive number, date, location, max depth, bottom time, water temperature, buddy, and notes. Eight built-in dive types (Reef, Wreck, Night, Drift, Wall, Deep, Cave, Boat) keep entries organized. A clean form fills out quickly between dives.

REVIEW
Each dive comes with a depth profile chart — a graph of how the dive unfolded over time. See what you did in the water at a glance, from descent to surface.

TRACK
Lifetime stats track total dives, deepest dive, total underwater time, and how many of each dive type you've logged. Numbers update automatically — no manual recalculation.

WORKS ANYWHERE
Fully offline. No account, no sign-in, no cloud sync, no ads. The app works on a rocking boat with no signal. All data stays on your device, in your control.

PRIVACY FIRST
No analytics, no trackers, no telemetry. Just a quiet logbook.

PAY ONCE, OWN FOREVER
No subscriptions, no in-app purchases, no recurring fees. Pay once and the logbook is yours.

UNIVERSAL APP
Designed for both iPhone and iPad.

Note: Fathom Dive Log is a personal logbook. It does not compute decompression schedules, render ascent-rate alarms, or replace your dive computer. Always dive within your certification limits.
