I would like to have a widget on my desktop (or in the navigation bar) where I can see the price of a couple of coins. The tool should allow to configure three, four or five coins out of list (perhaps you can use the coinmarketcap API).
I mainly use MacOSX but also Linux and Windows from time to time. Perhaps, there is a platform independent framework to build it.
Do you mean something preev.com by that watch several Crypto currencies ?
Most useful app is one to monitor BTC address's. Then you can monitor price, and amount in your BTC address's and not have to have access to account. So you can view amounts in paper wallets, hardware wallets, hot wallets, etc. And there is no security worries as it only can view.
I use apps like this on my phone to. It is great tool as I like to be secure but still monitor my addresses.
If I got you right it's something that watch addresses and give you notification when you receive something or you send something and show you the amount on the address and that kind of stuff ?
my idea
the most useful for me is trading aplication, like Z trader for android. but i need more than it.
i think you will be the first if you make dekstop altcoin trader. so we (trader altcoin) can focus at trading.
the aplication use api key from each market, like poloniex, bittrex, cryptsy, hitbtc, huobi etc.
don't make pro version or trial version, im sure trader will send you some satoshi as donation, and support your project.
I was never good at selling stuff anyway , so no worries , even if I do this It will be both open source and free .
