A clock that chimes every fifteen minutes
Yes — Horologe can chime every fifteen minutes, and it's $5.99, paid once. The quarter-hour chime is on when you want it and off with one setting, and the hour is counted out either way.
The spec, in prose: four faces — Mantel, Station, Chronometer, Nocturne. Five bells — Westminster, Whittington, Ship's Bell, Temple Bowl, Grandfather. Quarters on or off; the hour struck and counted, one for each o'clock. Quiet hours are silent from 10pm to 8am, and a right-click on the bell in the menu bar mutes everything at once. About three and a half megabytes, macOS 15 or later, from the Mac App Store.
Which bells chime the quarters
Two of the five, and they're the two English tunes. Westminster plays the full ceremony. Whittington is its rounder cousin and plays the same phrase on every quarter. Both mark the quarter-hours and then count the hour. The other three don't do quarters at all: Ship's Bell counts the nautical watch, Temple Bowl is a single struck note, and Grandfather just tolls. If you want the fifteen-minute chime, start with Westminster or Whittington.
What the fifteen minutes sound like
At a quarter past, four notes. At half past, eight. At a quarter to, twelve. On the hour, all sixteen — and then the hour itself, counted out, one stroke for each. It's the real sequence rather than a shortened jingle, and where the tune comes from is its own piece.
Quarter-striking is older than the tune. Tower clocks rang the quarters for people who owned no watch, so the street could hear the hour coming without standing in front of a dial. An hourly bell is the plainer version of the same idea.
How to make it stop
Three ways, and none of them takes more than a moment. Turn the quarters off and the clock keeps the hours to itself. Set quiet hours and it holds its tongue from ten until eight. Or right-click the bell in the menu bar and it's silent from that second, with the icon struck through so you can see it. Volume is a slider.
The honest advice for a first week is the same as it always is: hour only, volume low. The quarters are lovely, but they're the part people regret first. Living with Westminster is easier once you've heard a few hours of it.
The limits, in the same size
No alarms, no timers, no world clocks, and no ticking. It can ring during a call, because it can't see your screen or read your calendar and won't ask to. Muting it is one click for exactly that reason.
Horologe is $5.99 once. It chimes as often, or as rarely, as you tell it to.
