## What is Kaikoku?

Kaikoku is a classic × chuuni pocket-watch alarm app — built from a notebook the developer wrote in junior high and rediscovered decades later.

An antique pocket watch hangs from a real-physics chain in your palm. Snap the hunter lid shut and power gathers; open it and the day is unsealed. By night, wind the dial to cast one of twelve zodiac arcana. By day the sun seals your sorcery — six solar arts answer instead. Shut the lid and wind, and six seal-curses act upon the lid itself.

Rites await: cover the sensor to summon a fleeting night; touch a torn page of forbidden curses and the watch examines its keeper by Face ID — the owner unseals the chapter, while a stranger is shown a magic circle bearing an inviting sigil. Spin too far — thirty-six turns, one full day of the arcane world — and the chain sunders, until you resummon the watch by rite.

It keeps real time too: alarms with six bells, a magic hourglass timer, a chronograph with Live Activities, an Apple Watch companion that resonates with your pocket watch, widgets, StandBy, and a wall-pinned grimoire recording your deeds and chants.

Every spell, art, and bell is free. Ads help keep the watch wound — forge the Pact (lifelong or monthly) to still them for good, or invoke a brief Farsight rite to send them away for a while.

Time is no stream, but an illusion dwelling in the heart. The one true magic is to carve the now.
