Ive tried most of the crypto currency apps here and this is easily my favorite. The interface is intuitive, informative, clean and very useful. Best of all you can have the current BTC price displayed as a watch complication, so its front and center all the time. Best of all the developer is friendly, responsive and eager to respond to user requests. In my first review I asked for the ability to set a coin price as the app badge and he added it with the next update. I cant ask for better, especially for a free app! The only feature missing is the ability to send him some BTC to say thanks. (Hint, hint.) Really nicely done.
