Should add some more features
There could be lot more info to make the device much better: Battery % Number of passes Number of contact with ball Does the device have gps/beidou chip? Maybe Position map, heat map And there should be some kind of adjustment to set for speed/acceleration, speed for 8 years old compared to 15 year old is very different, 1 standard for all doesn’t make sense, especially lot of the users are kids, they grow so fast, standard should change as they grow up
