I travel a lot, often to different time zones, and instead of having muck around with hotel alarm clocks, my phone alarm always goes off at the same time every morning relative to the local time.
And there's no alarm clock at home that buzzes in the morning and annoys the heck out of my neighbors before shutting itself off after 30 mins.
A phone also doesn't blink 00:00 when the power goes out.
But the most effective alarm clock I own is a good old-fashion quartz clock AM/FM radio. It's WAY louder than any phone or tablet can offer up, and having it is often more reliable as well, given that my phone sometimes needs a hard reboot after installing a security update and hence isn't booted when I wake up, or didn't align for charging correctly and ran out of battery while sitting on the charging pad.
On the other hand, the battery in the Xoom mitigates the risk of my alarm not going off due to a power outage, and it being smart mitigates the risk of being late due to a time change.
Mine predates the recession, and I still rely on it. I have it on my dresser, such that I need to stand up and get out of bed to turn it off. Hey, while I'm up, let's start the day.
In any case, everybody has different circumstances. Parenting is an improvisational pursuit, every kid has different needs. In my kid's case, end-of-semester sleep deprivation has more than typical impact because of hypothyroidism that requires carefully adjusted medication and really benefits from a regular sleep schedule. Engineering school? Regular sleep schedule? Pffft. So I cut some slack. Their tendency to over-sleep alarms is partly wonky body chemistry.
I recall oversleeping for a final. Luckily, it was an intro programming, you-mean-I-can't-test-out-of-this?? class. I walked in a hour late, and left a 1/2 hour early. Had that been DiffEQ or similar.... errrf.
Tho with VoD dominating all entertainment, what are kids doing nowadays when waking up early at a Saturday?
Though, like everything these days, I heard there is an app for that. Swipe to snooze. Calculate some math problem and enter the answer for alarm off. Haven't bought the app myself yet.
I set two alarms: 5 and 6. If I make my first alarm, I get an hour to myself. If I don't, I scramble to get ready before my kids wake up.
Since moving my phone, I have slept better (no more late night time wasting in bed) and I have gotten up at 5 more reliably. I'm not really a morning person, but I enjoy the morning schedule better than my previous "schedule" (kids wake me up by screaming).
Honestly though, I'm still shocked at the number of people who are on a screen that soon. That can't be healthy for the eyes.
An answer like "for some reason manufacturers only use garishly bright LEDs" is (too) true, but not really about it being digital (c'mon eink!), while answer like "I find analog clocks to be prettier/more elegant" can be true but is clearly subjective.
I've just never understood the desire to have a clock that doesn't tell the time but instead shows some foreign representation of the common understanding of time (and not too precisely at that). That doesn't mean there is no argument I'd find persuasive, I've just not heard it yet. Care to share?
It's probably just how I was brought up.
Thanks for the answer!
Since starting the day with an out-of-battery phone isn't very pleasant, it's been very effective at preventing phone use before bed. It still works fine for alarms, or, if I'm on call, pages.
