OK, I might be late to the game here, but I just learned about an app called Strike. Like many other apps in this category, it allows you to purchase, sell, pay with, and basically transact in Bitcoin; however, the platform uses the Lightning Network to perform all the transactions with basically no fees. So, if you ever thought that you can't pay for that cup of coffee or a burger with BTC because the fees are more expensive than the value of the items, well... this is an app you should try. Stike is available for both Android and iPhone devices, as well as a Chrome browser extension.
