In this first beta release it allows monitoring of any Bittrex, Mintpal, Cryptsy and Poloniex markets. I've tested it using Chrome, Firefox and IE11.
Current roadmap (in no particular order):
- night mode (dark theme for night time use)
- add other exchanges
- automatic update of Cryptsy markets (currently I have to manually update the list of markets each time Cryptsy adds a new one. Other exchanges are updated automatically)
- provide a choice of alarm sound
- add push support for those exchanges that provide it (currently markets are polled)
Pingo will always be free to use. Donations welcome of course!
