I've been using these android apps for a while, and I just wanted to share. I think they are great
Both apps got KRN/BTC, and Crypto Currency Converter also has KRN against most national currencies.

I also asked the guy behind https://chainz.cryptoid.info/ to make a block-explorer and add eKrona to the site.
Hopefully someone can help donate a little to him, if he adds it.
