Is your iPhone alarm not going off? 6 potential fixes that worked for me
It's not an isolated problem: many iPhone users have noticed their alarms are mysteriously failing to sound in the morning. Here's a potential fix.
If I were to hypothesize, most alarm failures stem from software bugs, misconfigured sound settings, conflicting Focus modes, or interference from the Attention Aware feature on Face ID models. A quick check on Twitter/X, Reddit, Apple Support, and TikTok shows many users complaining about their iPhone alarms suddenly not going off -- to the point where they've slept in, missed morning meetings, and gotten in trouble at their jobs. My advice: Set multiple alarms, try different apps, and have backup plans, because waking up 30 minutes late for work is a betrayal no one should have to endure, let alone repeatedly.
