Why STAmina is the best in class

Auto generated tables

Start quickly by entering your best result and choosing a difficulty. STAmina will generate O2 and CO2 tables that closely match your current level. As you progress, you can either fine tune created exercises or generate new ones that match your new best result.

Heart Rate and Oxygen Saturation tracking

STAmina can track your heart rate and oxygen saturation level via a compatible HR monitor / pulse oximeter. Collected data is presented in a chart form so you can easily analyse how your body reacts to the stress caused by apnea, how fast you recover after apnea intervals, how low the oxygen saturation drops during long apnea intervals, how you react to contractions, etc.

Contractions tracking

Whenever you feel a contraction and want to track it - double tap on the timer. The app will save the exact time of the contraction. After the exercise is completed, review all contractions, analyse charts, compare with previous logs. By tracking time of the first contractions and intervals between contractions you can track your progress and better understand your condition.

Highly customisable custom table type

A custom table type is a flexible constructor that lets you build all kinds of exercises that don't fit into common table types. Apnea walks? Pre-contractions exercises? Mild warmup routines? We've got you covered! Add rounds, set lengths (not only by time, but also until a tap), configure repeats.

  • Easy to use

    This is a great app that offers a lot of value for free. Custom O2 and CO2 tables are very easy to use. The structure of the workouts is very helpful and encourages progression.

  • Stamina Basic Application

    I’ve been using the Stamina basic app (free) for 2 weeks. I’m enjoying it very much. It helps me remain consistent and motivated with twice a day, daily training. I’ll be signing up for the upgraded version this week.

    Have noticed an improvement in my breath, holding and confidence underwater. Hopefully this translates to more confidence in the water.
