Startup Idea: All-in-one Swimming Coaching Software

Startup idea to develop a comprehensive software solution for swimming coaches. The software should incorporate functionalities such as meet management, practice databasing, admin, attendance tracking, meet planning and entries submission, all accessible across multiple devices.

I coach swimming, and we are severely lacking in functional software for coaching practices. At present, you can either get software for meet management or for practice databasing or for admin, but you can't do it all in one. I need a place to store practices, take attendance, plan meets and submit entries, and have it all available across devices.
