Apps for a
life in motion.

We build focused apps for how you
train, breathe, and move.

FTNSS

Every interval.
Measured.

Interval timers you build, routines that chain them, and heart rate on every phase — not one average at the end.

Train. Dive.
One app.

Breath-hold training, a full dive log and dive computer, and a social layer that's private by default.
