Apparently Apple gives away a free app in the Apple Store app, not to be confused with the App Store app. The Apple Store app is what you use to buy Macs and shop for accessories. But it also features an iOS app that you can get for free via an automatically-redeemed code in the App Store app.Confusing, I know. But the result is you get a paid app for free. It may be worth checking monthly to see what the offer is. In this case it is the $5 Obscura 2 photo app.
