Tidemark - Countdowns & Deadlines Track what matters. One purchase, no subscriptions, no ads - ever. Tidemark is a countdown and deadline tracker built for people who take their time seriously. Clean, fast, and designed for productivity - not gimmicks. SMART COUNTING Count all days, business days only, or set a custom schedule. Tidemark automatically skips weekends and public holidays so you always know the real number of working days left. On the event day, you'll see "TODAY" — not "0 days." WIDGETS THAT WORK Beautiful widgets for your Home Screen, Lock Screen, and StandBy mode. Small, medium, and large sizes. Multiple countdowns rotate automatically. Widgets always show something useful — never a blank screen. LIVE ACTIVITIES Pin a countdown to your Lock Screen and Dynamic Island. Watch it count down in real time as your deadline approaches. STAY ORGANIZED Countdowns are automatically sorted into smart sections: This Week, This Month, Later, and Past. Pin important deadlines to the top. Organize with custom categories and icons. MAKE IT YOURS Choose from 12 gradient themes or set a custom background photo. Adjust overlay, blur, and crop. Pick from 20+ icons. Share beautiful countdown cards with friends. BUILT TO LAST • iCloud sync across all your devices • Repeating countdowns (daily, weekly, monthly, yearly, or custom) • Flexible notifications — on the day, 1 day, 7 days, or 30 days before • Count up from past events • Custom display units (months, weeks, days, hours, minutes, seconds) • Supports English and Polish ONE PRICE. THAT'S IT. No trials. No premium tiers. No "unlock full version." Pay once, get everything — including all future updates. Every day counts. Start tracking yours.
