Read full descriptionHide full description
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.

Verdict
The clearest difference is update cadence: Countdown at every 4 days against OmniaChron's every 3 months. Countdown also leads on device support (5 vs 2). On price, ads, in-app purchases and iOS requirement there is nothing between them.
