A freediver descending — the kind of moment these tools prepare you for

A small library, kept up by Minseo

The tools.

Three quiet companions for freedivers, snorkellers, and the curious. The same things I would hand to a friend before they joined me on a morning. Free, no signup, kept up to date with the season.

Featured · The one to start with

Breathe-up timer.

A guided breathing sequence with a slow circle and quiet audio cues. The same pattern I run with guests in the first ten minutes aboard, before the first descent. Use it the morning of your trip, or any time you want fifteen quiet minutes back.

A short note

"I built the first of these for myself, and the rest for friends who kept asking the same questions before their first morning on a boat. They are free because the answers should be."
