Sports Training App

The Mobile Sports training App is required to process the videos and should show the following:
1. the speed of the bat/stick/golf putter/racket etc with which object was hit.
2. Speed of the ball/Object before hit and after hit
3. Angle at which the ball was hit by bat/putter. take the reference drawn on the ground
4. Use whatever is required, but the speed of processing should be fast and should be shown on the mobile app.
5. Share the details about video, how to record and how they will be processed.
6. This must work on iOS and Android seamlessly.
You must be descriptive about the app when you share your solution. You can share your solution directly and PM me and discuss with me.
Your quote and timeline must be there as I have given the complete description.
Nothing to discuss separately as whole description is given.
