Whether you travel frequently or trade multiple currencies on a daily basis, a currency converter will always come handy. There’s a handful of them on the App Store, but I’ve realized many aren’t intuitive enough when you need them the most. Indeed, when you’re trying to bargain a price in a local flea market and have to fight with your handheld device to get the conversion rate, you’re not at an advantage. The same applies when converting large amounts you’re trading, especially when you need to do it fast. Thankfully, Smart Coin solves the problem as it’s a gorgeous and intuitive app that takes a one-screen approach, so you get all the information you need at a glance.
