As a TV producer, I've been looking for something like this for a long time and finally Tempus has come around. Honestly, this app helps me in my day to day role so much and it's clearly been designed with professionals like me in mind. I've already shared this with everyone I know and I'm sure you will too, as soon as you try it. Brilliant common sense design.
Downloaded and it wouldn't open even once. As soon as I tap on it, it crashed.
