Mobile Application Idea

Hello I am new to this community, so hi! I am working on an idea for a mobile application and I was wondering if you would throw me your opinion on the following. 

I would like to create an app that lists the units from Starcraft 2, it would show stats and possible counters for each unit. 

I know there are already apps like this in the store, however I would love so feedback on this idea. Is this something that you would find useful? Are there any features you would like to have introduced?

Any feedback at all would be greatly appreciated.
