Breathe. Adapt. Perform.
Guided breath training for performance, recovery, focus and sleep. Two minutes before a session, ten minutes after a hard one, or a full set of retention rounds — plus the techniques that actually help at 2am when your mind will not switch off.
Perform
Prime your breathing before you train, and hold a cadence when the effort climbs. Sessions built for the ten minutes before it matters, not for a meditation cushion.
Recover
Come down after training, after work, or after a day that got away from you. Long exhales, no holds, nothing to learn.
Adapt
Progressive rounds and breath holds that get harder as you get better — with the safety screening that this kind of training actually requires.
Try it without downloading anything

Where the name comes from
ALISI takes its name from the alisios — the Atlantic trade winds that shape the Canary Islands. Constant, powerful, adaptive. A reminder that repeated forces build stronger systems.

The part other apps leave out
Breathing fast and then holding your breath lowers the carbon dioxide in your blood. Carbon dioxide is what triggers the urge to breathe — so the hold feels easy while your oxygen keeps falling. That is why people black out doing this, sometimes with no warning, and why it has killed swimmers who tried it in water.
ALISI screens you once for the conditions that make retention unsafe, confirms where you are before every retention session, and tells you plainly which sensations are normal and which mean stop. None of it is behind the paywall.
