Full disclosure: I am friends with the guys who created the app. But I have used it for some time now (including during the Frankfurt Major) and honestly think that they did an awesome job with it!
Some links:
They also posted on this subreddit a few days ago but unfortunately got burried.
The app itself is free to download and use. There are different stat panels available during a match. Usually, the app runs in "smart rotation" and decides which panels to show based on the match progression (works really well!). If you buy a subsciption (0,99 per month or 9,99 for a whole year), you can freely choose which panels to show.
I think the asked price is fair as they put a lot of work (and heart) into it and they are already planning on expanding it (see the original post and website) but if you want to try premium completely free for a whole month, just tap on the small gift box at the bottom right of the panel selection screen and enter the following code (case sensitive): Eaglesong2015
Just give it a try an feel free to ask questions and give suggestions. I will forward them to the devs!
EDIT: Typos...
