So, I recently downloaded your free app. I'm generally happy with it. It allows me
to know who may counter in a matter of a click. However, the reason why I give it three stars is because it is too simple.
At least three sentences to why a counter is a counter would be beyond helpful. For example, Teemo is a counter to Nasus because of his range, blind spell which does not allow Nasus to "q" farm, etc etc.
After a small description as to why they are countered, you should add a section on how to play against someone who counters you.
Another thing I'd like to see implemented is something where players can write their own strategies as to why counters are counters and how to face them. For example, if I were to click on a champion, that champion will would have the listed counters. If I were to maybe click or hold the countering chAmpion, it should have a description of things to do/avoid. Also, when clicking the champion in the champion selection, allow two separate tabs. One for public comments and one for integrated comments (the ones you originally added). That would allow different perspectives.
Nonetheless, I enjoy the app just not completely. It has so much potential. Many people who use apps usually use them when they're away from a computer so giving us things to read will allow this app to be used more and also have more value behind it.
Thank you hope to see some additions and if not, thank you anyways
