Onseol: Countdown Widget

Onseol counts the days that matter — no account, no sign-up. Every date lives only on your phone. • Korean-style D-day — D-DAY, D-100, and days-since counted from day 1. 100-day and yearly milestones, automatically. • Lunar (음력) birthdays & memorials — converted to the solar date each year. • Home & Lock Screen widgets — they survive iOS updates and stay date-sorted. • Reminders — D-7, D-DAY, and milestones, all on device. No subscription. No account. A one-time Pro removes the ads and lifts the event limit.
