iWorkUntil turns the time you have left into something you can actually see — every minute is a visible block, the grid fills as time passes, and one glance tells you where you stand in the day, the session, or the workday. Built for anyone who'd rather see time than read it. Especially good for ADHD focus sessions, deep-work blocks, study time, and any moment where "how long left?" is the question that matters. No accounts. No ads. No notifications. No streaks to break. No AI nagging. Just time, made visible. WHAT IT DOES • Visual countdown — your time as a grid of blocks that fills as it passes • Pick a duration (e.g. 25 minutes) or a range (e.g. 9 to 5) • Each block represents a slice of your time — at a glance, you know where you are • Choose a theme that fits your screen • Lives in the corner — never in the way WHO IT'S FOR • Anyone who loses track of time when they're focused • Visual thinkers who do better with shapes than with numbers • Pomodoro and deep-work sessions that need a clear stop signal • Workdays, homework, study breaks, screen-time wind-down • Cooking, exercise, meetings, presentations — anything time-boxed WHAT IT DOESN'T DO • No notifications. No dings. No dopamine traps. • No accounts, no logins, no data collection. • No ads, no subscriptions, no upsells. • No AI, no streaks, no guilt. A visual countdown that shows you time, instead of telling you about it. Available in 11 languages: English, German, French, Spanish, Dutch, Polish, Hungarian, Russian, Danish, Swedish, Slovenian.
