Bathyal
Read full descriptionHide full description
Bathyal is a clepsydra — an ancient water clock — rebuilt for the deep sea. In the bathyal zone there is no day or night. No sunrise, no shadow, nothing to set a clock by. The only light is made by living things. Bathyal is the instrument that keeps time down there: a face of glowing concentric channels where every drop is a second, and time is material. Watch it work: • Each second forms as a drop at the heartbeat and joins the ring • A full ring of seconds distills into one minute — and pours, visibly, down into the next channel • Minutes pour into hours, hours into the day's two halves, days into months — at midnight the whole cascade runs at once • Once a year, the last drop of December sinks past the digits into the abyss, unmeasured Make it yours: • Solid bands or beaded drops, sweeping or pulsing motion • 24-hour or 12-hour time — 12-hour splits the hours at the meridian into a morning ring and an afternoon ring • Calendar rings for the month and year, or a Monday-first week ring whose weeks are spent, not kept • Run the midnight cascade demo any time from the settings On your wrist: • A full-screen water clock for Apple Watch — seconds, minutes, and hours in the same adjacent channels • Add Bathyal as a complication; the live rings sit on any face and rewrite themselves as the day moves. No two times look the same — that is the instrument, not a hand on a circle • Hold the Watch face for settings. Pulse or sweep, 12- or 24-hour time, and an optional Monday-first weekday ring. Hours, motion, and the week calendar also travel from the gear on iPhone On the Lock Screen: • Add Bathyal as a Lock Screen widget — live rings, a different pattern for every minute, the same figure as the Watch complication • Hours, motion, and the weekday ring follow from the gear Quiet by design: • Completely free, no accounts, no ads, no tracking — it never connects to anything • Works fully offline • Keeps the screen awake on a desk or bedside table If the instrument keeps good time for you, you can send a drop — a small tip — and the face answers with the benefactor tinctures: other colors of bioluminescence, and a single grain of sand set on the seabed of the dial. Drops become months.

Verdict
The clearest difference is ads: Bathyal at none against Flip Clock's shown. Flip Clock's advantage is iOS requirement (13.0 vs 16.0). On price, update cadence, in-app purchases and device support there is nothing between them.
