I love this app- it's my main go-to portfolio manager for crypto.
Although I like the coin voting I wonder if entire exchanges shouldn't just be listed? There are some obvious coins such as Monero and Bytecoin (BCN- not to be confused with it's namesake BTE) missing- and many new coins on Poloniex that are getting popular- why not just add the entire exchange?
Additionally, you should absolutely add the coins on masterxchange.com- it's a main trading exchange for mastercoin and maidsafe (if not the only exchange?).
Anyway, great with developing and updating the app!
I think it's quite a hard job to add all these coins and exchanges. If it's not, the dev definately should add more coins and exchanges, which makes this app even better! However, if many coins are added, we should have an option to select coins we want to see on the first page ~ the current value, as I don't want to scroll 5 minutes ^^.
Just my 2 cents, I still use this app a couple of times a day!
