A complete dive in a few focused minutes
Descend beside the line, equalize on cue, take the tag, turn cleanly, match your kicks on the ascent and stay calm through the final glide.
The dive becomes a rhythm
Every prompt uses the same universal action, whether the watch has touch, five buttons or fewer controls. Timing can be PERFECT, GOOD or MISSED; the FLOW meter turns those moments into a readable arc instead of a wall of numbers.
Fifteen depths, five real seas
The campaign begins at 10 metres in the Sea of Cortez and climbs toward an intentionally aspirational 150-metre finale in the Greenland Sea. Water palettes and wildlife change with the location and depth: sea lions, turtles, thresher sharks, mantas, hammerheads, narwhals and orcas move through the background.
From the buoy to the tag.
Designed for actual Garmin hardware
The interface is deliberately sparse and readable on a small round screen. It supports physical buttons and touch without changing the rules, and ships with separate high-colour AMOLED and palette-safe MIP presentation.
Free, offline and private
Deep Line does not require an account, network connection, sensors or permissions. Campaign progress and best scores stay locally on the watch. No personal data is collected or transmitted.
An arcade game, not safety equipment
The depths and techniques create the fiction of the campaign; the app is not a breath-hold trainer, dive computer, medical device or safety tool. Never use it during a real dive or breath-hold session.
No user data leaves the watch
Deep Line collects no personal data and uses no analytics, advertising SDKs, network services or ANT+ profiles. Local progress can be removed by uninstalling the app or clearing its stored data on the device.
