Pocket Alarm turns your iPhone into an interactive pocket watch with practical alarm tools. Set alarms with clear weekday controls, choose sounds, and use a timer up to 23:59:59 with hours, minutes, and seconds. Stopwatch, World Clock, widgets, Live Activities, Apple Watch, and a landscape Desk Mode keep time visible wherever you need it. The watch responds to motion, winding, its hunter-case lid, and an on-screen chain. If the chain breaks after extended winding, restore it through a short touch game. This game has no purchase, prize, currency, or random reward. Day and night automatically change the watch's atmosphere while preserving the same classic typography, metal finishes, and mechanical movement. Eligible monthly and annual plans include a three-day free trial. Monthly, annual, and lifetime access are available through Apple's in-app purchase system. Trial eligibility and final terms appear in Apple's purchase sheet. Terms of Use (EULA): https://pocket-chime-alerm.cavemen.jp/terms/ Privacy Policy: https://pocket-chime-alerm.cavemen.jp/privacy/
