Read full descriptionHide full description
Time, shown as a single bar. ProgressTimer is a minimal landscape timer that turns elapsed time into a full-screen progress bar. For pomodoro sessions, workouts, cooking, presentation rehearsals — anywhere you want to see time at a glance, even from across the room. ◆ Two modes Count Down Set a duration and watch the bar fill from empty to full as time elapses. Count Up Start from zero and let the bar grow toward your target duration. Both modes auto-stop when the target is reached and play your selected alarm tone. ◆ Landscape × giant progress bar Numbers are secondary — progress is the point. A monochrome bar fills the entire screen so you can read your status from a distance. The time is rendered in a large monospaced number at the center, optimized for legibility against the moving bar. ◆ Lock Screen & Dynamic Island Full Live Activity support. The progress bar and remaining time appear on your Lock Screen and in the Dynamic Island. Play, pause, and restart the timer without ever opening the app. ◆ Keeps running in the background Closing the app or locking your screen doesn't stop the timer. When time's up, a local notification fires with your chosen alarm tone — Beep, Chime, Bell, or Digital. Use the system volume or set an in-app volume independently. ◆ Icon-first interface No text labels — every control is an icon. From mode selection to duration setup to start, you can begin a session in three taps. Designed to stay out of your way. ◆ Features ・Count Down / Count Up modes ・Hours / Minutes / Seconds wheel picker (up to 24 hours) ・Full-screen progress bar (landscape-only) ・Live Activity (Lock Screen / Dynamic Island) ・Pause / Resume / Restart from Lock Screen ・4 built-in alarm tones + none ・System volume or in-app volume slider ・Local notifications for background alarms ・In-app language switching (English / Japanese) ・Theme support (System / Light / Dark) ・Pure monochrome, distraction-free design ・Locked to landscape for fullscreen visibility ◆ Completely offline, completely private ProgressTimer makes zero network requests.

Be the architect of time. Turn the dial, set the rhythm that feels right for you. Who said a second has to be a second? In the world you create, may you find your peace. Chronos is not another 25-minute timer. It is a focus clock built on one quiet truth: we all live in our own time. Some of us flow best at midnight. Some find our rhythm in the early morning. We each feel time differently — what feels like a second to you might stretch into a minute for someone else. And all around us, every moment on this planet, life unfolds at its own pace: a bird takes its first flight, a snowball rolls down a hill, a whale grows beneath the waves. To notice this is to find peace. WHAT HAPPENS IN AN HOUR • Twelve living watercolor worlds move with your clock. Watch a whale breach at dawn, mist drift over karst peaks, golden dunes shift in the wind, aurora dance across snow, and the galaxy bloom over midnight. The sun and moon trace real celestial arcs across the sky. • The world responds to you. Brush the screen and wind ripples through the grass. Tap a bird and it banks away. Touch the water and waves spread outward. Every sound is synthesized from pure mathematics — no recordings, no loops, just quiet, living whispers. • Life grows as you work. Eagles court, brood, and hatch their young on the cliffside. Two ships cross the evening sea to meet. Your focus becomes their story. WHEN THE HOUR ENDS It burns. Gently, completely. Then you mark it: one needle, five weights of time, a line if you wish, and your seal. Every hour has its weight. THE FRUITS OF TIME Your history is not a spreadsheet. It is an orchard. Every day is a tree. Every focus session is a fruit. Weekends glow in terracotta. Scroll back through your seasons, and see your time bloom. No account. No ads. No tracking. Your hours belong only to you, and stay only on your phone.
