Well, I'm a developer and not a sales guy. But since you asked... ๐
The creator of Ump-App and the instructor in the videos is D1 Umpire Tim Cordill. If you've been to a clinic in the greater Midwest, you may have met him. To say he's passionate about umpire development is an understatement. He eats, sleeps and breathes umpire development and it shows in our content. Our platform is comprehensive. And I do mean comprehensive. In the Baseball Umpire course, there are over 500 short videos (more than 12 hours total) broken down by situations into several categories. There's a test at the end of each section to help in retaining the information. A one year subscription gives you access to the entire course for the entire year. The videos can reviewed any time during the year if you'd like to look back at a certain situation.
Video based training is an excellent way to cover a lot of information at your own pace and on your own schedule. There's no way you can sit down in a preseason umpire meeting and cover a fraction of the information we do. Our platform is also mobile friendly so the site is accessible wherever you you go.
I'm a big fan of clinics and I've been to several. They are excellent. Video based training, however, is a powerful educational tool that will only continue to be a bigger part of how we improve and prepare for our seasons. The knowledge you gain will make you more confident on the field.
If you have any more questions, I'd be happy to respond.
