Bitcoin Watcher description

This app monitors the current BTC price and notifies you when your low/high set points have been reached. It will also allow you to be notified when a certain % change in price has happened within your period of time.

When you launch the app it will show your exchange, the current buy price, sell price and last price. It will show the ratio of the current buyers vs the current sellers. It will show a 24 hour price chart, and your Low/High set points. The bottom of the screen displays how much change has happened in time you have chosen. It will also notify you when a set point has been reached.

When you remove the app from view, it will continue to monitor the price at your chosen time frequency and notify you when a set point has been reached.

Options allow changing data update frequency for battery/data limiting. Also there are different fonts and color themes.

Nitty Gritty:
The two bar graphs get current order info from the highest volume exchange (currently BTC China). The app takes a ratio of the buy/sell orders currently in place that are within 2% of the current price. This is intended to give you an idea of how many buyers there are vs sellers near the current price. There is no way to gauge the unknown amount of spontaneous traders but at least we can get some info from the books.
