Turn off select lock-screen notifications
Tinder messages, Neko Atsume updates, and other embarrassing notifications always pop up on your screen at the most inopportune moments. You can control which apps do what when your phone is locked, so hide that shit! Go to Settings > Notifications and scroll to the offending app(s) and uncheck "Show on Lock Screen."
Bonus tip: when you're in the company of others and you don't want them to see who's texting you, you can set it so that it simply reads "New Text Message" on the screen instead of the contact's name. From the Notifications settings menu, select Messages and uncheck "Show Previews."
