Read 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.

About

Drift

Features
Read full description

Drift is a random timer for moments when fixed intervals make you watch the clock. Set a floor, target, and ceiling, then let Drift ring at gentle unpredictable times that still average near your target. Use Drift for trainer-bike position changes, standing desk resets, stretch breaks, focus sessions, hydration nudges, meditation bells, or any reminder that should feel helpful instead of rigid. Pick a preset, choose a sound, and start a session with one tap. Your presets, settings, generated sounds, and session summaries stay on your device. Drift is free with banner ads and occasional cooled-down interstitials; a one-time Remove Ads purchase removes all ads permanently. Optional custom sound credits let you generate short AI interval cues from prompts you type. Notifications are optional and only used for your active timer.

Verdict

The call
