The PowerChalk - 10 Second Telestrator allows you to analyze sports video clips taken with your iPhone or iPad. Clips can be selected and 10 second segments can be played in slow motion, paused and reversed. Motion analysis sessions can be recorded including markup and voice-over.

The app is perfect for golf pros, baseball coaches and more. No other video app gives you the finite control of PowerChalk's 10 Second Telestrator while fully integrating to a cloud storage system for collaboration and sharing.

Good but needs improvement

The app only allows for 10 second videos. It needs to allow unlimited video length. It doesn't have to have multiple frames. Simply allowing a video of any length to be paused for editing or notes would be ideal.

Shows promise

This app is only marginally useful due to a confusing interface, bugs, and occasional crashes. Free is not an excuse. This was my first impression of PowerChalk and I'm not impressed. That said, this app shows a ton of promise, and can be a killer app with just a few little tweaks. I'd be happy to critique it and help test a beta version if I can get a truly usable version.

Not a very functional app for iPhone 5

My main complaints...the menu option names don't line up to the selectable sections, also, after reviewing one video in chalktalk, exiting that video takes you back out to the log in screen, not too mention the many bugs... just stick with the website and don't waste your time with the app
