Review momentum

faster than 0% of Sports apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

◉ 6 APNEA TABLE OPTIONS
STAmina Apnea Trainer can create / generate custom apnea (exercises that are automatically created based on the maximum breath-hold and match the user’s level) or let you select from the following customizable table types:
- O2 deprivation table – accustoms a body to lower oxygen levels. This is achieved by increasing the amount of time that you hold your breath on each attempt, while the resting time is fixed.
- CO2 Tolerance table – helps a body to adapt to high carbon dioxide levels. This is achieved by decreasing the length of resting time between fixed breath-hold periods.
- Wonka table – a variation of CO2 tables. Apnea timer starts after the first contraction, the rest time takes one breath.
- Mix table – tables where apnea time increases and rest time decreases with each round.
- Custom table – allows mixing of different approaches to create a custom training, thus generating the most effective training program.
- Pranayama – a breathing technique to decrease stress in the body and relax the nervous system.
