This widget does nothing but display the current BTC-PHP exchange rate. The rates are provided by Coins.PH, a bitcoin company based in Manila, Philippines. The app is ad-free. However, I included my referral link in case you want to open an account at Coins.PH. We will both receive PHP24.00 if you register using the link I provided in the app.
HOW TO ADD THE WIDGET1. Start out by long-pressing a blank, available space on your home screen — not on an icon or the app launcher. Just hold your finger down on the screen.2. Touch the Widgets option from the menu that pops up. With the Galaxy S4, the Apps and widgets selection will take you to the app launcher, with widgets organized alphabetically behind all the apps. So just swipe right through to that section.
