I have to imagine that this is an aim-assistance scenario. CS does not have aim-assist in order to prevent abuse by M&K players. Most other games have toggles in the settings for contrller use.
You could always try one of the more precise deck aiming schemes like flick-stick+gyro.
Big fan of the PineTime for minimalism and extraordinary battery life, but the Bangle looks compelling. Maybe once the PineTime dies.
