- 2D and 3D representations of the trajectory of the ball have been introduced in order for the users to be able to analyze their shots.
- Added a map of SPEEDUP hot spots, i.e., places around your current location where SPEEDUP app users gather to take part in a speed challenge and/or practice together.
- The user interface has been designed so that speed measurement sessions may be shared with a large audience through mobile streaming (on platforms like twitch, Facebook, YouTube, etc.), screen mirroring, bluetooth speaker pairing, and speed broadcasting on the SPEEDUP Live web interface.
