JuanStocks is a tool you can use to monitor the Philippine Stock Exchange.
With JuanStocks, you can save the stocks in a portfolio (or just a watchlist) and set the buy/sell price for each of them.
JuanStocks gets its (almost real-time) data from the Philippine Stock Exchange; thus, internet connection is required. The stocks you saved on your portfolio and watchlist, including their buying/selling price, are stored only in your phone and not saved online.
