02 / How they work

More reasons
to keep going.

01

A plan before you dive in.

Aquach builds each session from your level and goals — warm-up, drills, main set, cool-down — and takes it to the pool on Apple Watch.

02

Every kcal is breath.

Soomcha reads your active energy from Apple Health. Every 1 kcal becomes 1 soom, the breath that keeps the village going. Run out, and the residents rest.

03

A village with a mind of its own.

Residents plan their own days, talk to each other and remember what happened. A rumor heard today can change where they go tomorrow.
