Bathyal is a clepsydra β an ancient water clock β 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: β’ Each second forms as a drop at the heartbeat and joins the ring β’ A full ring of seconds distills into one minute β and pours, visibly, down into the next channel β’ Minutes pour into hours, hours into the day's two halves, days into months β at midnight the whole cascade runs at once β’ Once a year, the last drop of December sinks past the digits into the abyss, unmeasured Make it yours: β’ Solid bands or beaded drops, sweeping or pulsing motion β’ 24-hour or 12-hour time β 12-hour splits the hours at the meridian into a morning ring and an afternoon ring β’ Calendar rings for the month and year, or a Monday-first week ring whose weeks are spent, not kept β’ Run the midnight cascade demo any time from the settings On your wrist: β’ A full-screen water clock for Apple Watch β seconds, minutes, and hours in the same adjacent channels β’ 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 β that is the instrument, not a hand on a circle β’ 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: β’ Add Bathyal as a Lock Screen widget β live rings, a different pattern for every minute, the same figure as the Watch complication β’ Hours, motion, and the weekday ring follow from the gear Quiet by design: β’ Completely free, no accounts, no ads, no tracking β it never connects to anything β’ Works fully offline β’ Keeps the screen awake on a desk or bedside table If the instrument keeps good time for you, you can send a drop β a small tip β 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 in-app purchases: KeyCodeCheck at none against Bathyal's 3. Bathyal's advantage is update cadence (every 10 days vs every 2 months) and device support (4 vs 2). On price, ads and iOS requirement there is nothing between them.
