About

Big Day

Big Day turns the dates you're excited about into bright, glanceable countdowns you can pin anywhere — your Home Screen, Lock Screen, and StandBy. Holidays, birthdays, trips, paydays, due dates, anniversaries — add a countdown, give it a colour and an icon, and watch the days tick down (or up) every time you glance at your phone. WHY BIG DAY • Start free — create your first countdown and pin it as a widget, no account needed. • Beautiful, brightly-coloured cards that look great on any screen. • The little details other countdown apps get wrong: it says "Today" at zero, handles "1 day" correctly, and uses your local time zone — never UTC. WIDGETS, EVERYWHERE • Home Screen widgets in small, medium, and large. • Lock Screen widgets — rectangular, circular, and inline. • StandBy support for your nightstand. • Configurable: pick exactly which countdown each widget shows. MAKE IT YOURS • Curated colour palette for every countdown. • Icon and emoji picker. • Widget styles: number, progress ring, progress bar, or photo background. • Adjustable text size and legibility. COUNT DOWN — OR UP • Countdowns to future dates, and "days since" counters for the past. • Repeating events — annual, monthly, or weekly. • Local reminders as your big day approaches, plus a day-of nudge. TEMPLATES & SHARING • Seasonal and holiday template gallery — browse and add in a tap. • Export a shareable countdown card for any event. PRIVATE BY DESIGN • No account, no sign-up, no tracking, no ads. • Your countdowns sync automatically through your own iCloud — free, login-less, and only you can see them. We never receive your data. BIG DAY PLUS Unlock the full colour library, photo-background widgets, shareable countdown cards, and unlimited countdowns with a yearly subscription or a one-time lifetime purchase. Your free countdown and widgets keep working either way. Questions or feedback? Email coraliadigital@icloud.com — we read everything.
