Cultured Code’s popular task management app, Things, is now free for a limited time. The productivity app is being discounted as part of Apple’s week-long “Free App of the Week” promotion and is the first time the app has ever been offered for free. The sale extends to both the iPhone and iPad version of the app, offering a combined savings of $30 on the two iOS apps. Things for iOS normally is priced at $9.99 for the iPhone version and $19.99 for the iPad version. To celebrate this promotion, Cultured Code also is lowering its price on Things for the Mac ($34.99), taking 30 percent off the full $49.99 price of the app.
