Silently set an iPhone alarm
It's late at night, your spouse is already asleep, and you realize you before you go to bed that you need to set an iPhone alarm to wake you up the next morning. You launch the Clock app, schedule the time, and then want to adjust the alarm sound to be sure it's loud enough to startle you awake tomorrow. As you begin to tap the sound, though, panic strikes: You remember that the iPhone helpfully previews the sound the moment you tap it—so, essentially, your alarm will go off, wake up your loved one, and make nobody happy.
Hints reader imaldonado found the quiet solution: When you're choosing your alarm sound, double-tap it instead of single-tapping it. You'll select the sound without auditioning it first. And that should let everyone sleep better.
