Everything is going well, until you turn and notice a popup on your yule log imploring you to upgrade to premium. That’s the situation facing users of “Winter Fireplace,” a digital yule log on the Apple App Store. “Experience Winter Fireplace at its best,” the popup — viewed by Futurism at a holiday party — merrily declares.
