Sometimes it's an app, but other times it's an anti-app.The App: Discover Books You Won't Find Anywhere Else
Algorithms run everything now...except this app. It offers good, old-fashioned serendipity—like you used to get browsing a bookshop or library. There's no way to pick categories & no way to follow your friends. There's just quality, hand-picked ideas: some you'll love, some you'll hate, and some you won't be sure how to react to at first.The Anti-App: Fight Smartphone Addiction
Smartphone addiction is real. This app fights it. There's a timer that delays updates to prevent endless time-killing browsing. Also, it's not social, it actually respects your privacy, it doesn't show any ads, and its content is not trivial—so the little time you do spend on it is time well-spent.
