OmniaChron vs Countdown

OmniaChron is a visual day counter for countdowns, count-ups, date ranges, and real-world progress. Track days until important events, days since meaningful milestones, or progress across any date range. See every timeline as a clear percentage, with progress bars that update in real time. Use OmniaChron for launches, school terms, work deadlines, sprints, vacations, anniversaries, seasons, retirement dates, personal milestones, and anything else worth measuring. What you can track: • Days until future events • Days since meaningful dates • Progress across date ranges • Working time based on your schedule • Repeating timelines and cycles • Year, quarter, month, and today progress Key features: • Three tracker modes: Range, Countdown, and Countup • All-day or exact-time tracking • Per-tracker time zones for travel and accurate dates • Working-time rules for weekdays, work hours, breaks, and public holidays • Explain view showing calendar time vs. working time • Breakdown of excluded days, usable time, and total time • Repeating trackers: daily, weekly, monthly, yearly, weekdays, and custom intervals • Milestone reminders and local notifications • Ready-made templates for basics, work, school, seasons, sports, streaks, and events • Share tracker cards as images or text • Import, export, and full backup restore with .omnia files • Dark and light themes, accent colors, and adjustable UI size • Local-first privacy with no account required Why OmniaChron is different: Most countdown apps stop at “days until.” OmniaChron also shows how much progress has actually happened and, when needed, how much usable working time is left. Exclude weekends, holidays, breaks, and off-hours. Then compare calendar time with working time so the number on screen makes sense. Free and paid: OmniaChron includes free trackers plus built-in timelines for year, quarter, month, and today. Unlimited trackers are available with Unlock Forever. No subscription required.

Count down the days to every big moment: birthdays, trips, weddings, holidays, exams and due dates. Countdown shows each event live, down to the second, and puts it on your home screen with a widget. Live countdowns Days, hours, minutes and seconds, ticking live. Switch any event between days, weeks and hours with a tap. Home-screen widgets Put any countdown on your home screen: one event per widget, small, medium or large, in three styles. Each widget works out the days by itself. On iPhone, widgets need iOS 17 or later; there are Lock Screen widgets too. Days since Count up from a date to follow anniversaries, streaks and milestones in days, weeks or hours. Reached milestones are ticked off. Your own style Choose a colour gradient, a photo from the background packs or one of your own photos. Each countdown gets its category and its occasion art. Reminders Get a reminder 30, 7, 3 or 1 day before, on the day itself and at milestones. Yearly events roll over to next year on their own.
