To use Cus­tom Vibra­tions, open the Set­tings app, tap “Gen­er­al” then “Acces­si­bil­i­ty” then turn Cus­tom Vibra­tions on. Now in Set­tings tap “Sounds,” then “Vibra­tion” under the head­ing “Vibra­tion Patterns.” At the bot­tom, tap “Cre­ate New Vibration.” Start tap­ping on the screen, and your pat­tern of tap­ping will be record­ed for use with any alert. You can make sev­er­al of these. The most com­mon use for Cus­tom Vibra­tions is to be able to tell who’s call­ing when your iPhone is in silent mode.
