Have the coaches used the Super Coach app? What is the biggest feeling after using it?

It is very practical to download a super coach APP on the mobile phone, because you don't have to keep all the information of the trainees in your notebook at all times, you can record it at any time and check it at any time with the mobile APP. Now I can not only keep track of the students' situation at any time, but also release the arrangement of buying a car and practicing. Both students and I save trouble, and the APP can record students' practice scores in real time, which makes my exam arrangement more appropriate.
