STAmina is created by and for freedivers with the ultimate purpose to improve your freediving skills by increasing the breath-holding time. STAmina is all about O2 deprivation and CO2 tolerance tables. It allows you to configure the tables to correspond to your skill level. It leads you through a workout with visual and voice notifications and tracks the history of your workouts.
