I'm always baffled by heavy Calculator users, to be honest. I've never understood the popularity of dedicated calculator apps or widgets, on any platform. 90% of the time you can simply round numbers in your mind, and if precision is necessary for big numbers that's likely a job for Excel.
Same for clock apps. Clock in your taskbar, sure; but who would ever start a dedicated clock app? I barely touch Contacts and always from other apps. Photos is terrible, but that's been the case for a while now, the obsession with hiding the filesystem has degenerated in an unusable interface (sharing in particular is just mystifying).
Of your list, I do use Messages (you don't really get a choice, if you want to receive SMS texts...) and Safari (again, no real choice), as well as the Camera simply because I use it so little it's not worth my time looking for a better app.
That's where the alarm is, and personally I use it several times a day, to wake me up and to remember the occasional meeting or random events I would otherwise forget about.
I hate ios Photos, mostly because of the white backgrounds however.
Good point. I never really used alarms until Siri, because it was too cumbersome. Now setting and deleting alarms via Siri is probably the best voice-recognition experience I've ever had.
