Yes, since application version 1.1.6 it is possible to have the display always on during an event (Sport mode).
To keep the display on, please go to your PulseOn application and open its settings menu, choose Device Settings -> Screen options -> Always on.
For longer sport events and in sports when you don’t need to know your exercise details frequently, we recommend using 'Power save' option. To do so, please choose Device Settings -> Screen options -> Power save.
With 'Power save' on you can still check your event details by pressing any button. Device screen will turn off automatically after a few seconds to save energy.
