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.

Sit Still is a focus timer and app blocker that gives you somewhere to be. Most focus apps punish you, Sit Still keeps you company. A cat sleeps in a painted room while you work, and the reward for sitting still is a collection you build. Blocking is real, and as firm as you want it to be. The rooms are the heart of it: watercolour illustrations painted like the pages of a childhood picture book, meant to feel cozy and nostalgic — to stir a memory of being small and safe somewhere — each with its own soundscape. APP BLOCKING FEATURES Three app blocking modes for a focus session: Open, Whitelist and Strict. Additionally, app blocking rules allow you to put away the apps that keep distracting you throughout the day. You can lock the apps on a schedule of your own or hold them to a daily limit. You can also set a bedtime lock on a night schedule you choose. WALLPAPERS AND WIDGETS Any room you have can be saved to your Photos as a wallpaper, drawn at the full resolution of your phone or iPad, with your cat in the corner or without it. There are widgets too: the room you are sitting in with your focus stats under it, the collection with a different room every hour, a calendar of the month with your cat beside it, and your streak on the Lock Screen and in StandBy. A TIMER WITH THREE SHAPES Countdown, open-ended, or pomodoro. The pomodoro starts at the classic 25 / 5 / 15, and all three lengths are yours to change. A session carries on with the screen locked, and shows itself on the Lock Screen and in the Dynamic Island. A COLLECTION OF ROOMS A permanent collection of rooms, from a bookshop loft in Porto to a stilt house on the Mekong Delta, and two new rooms on the first of every month that leave with it. Every room has its own illustration and its own ambience loop, levelled against all the others so changing rooms is never a lurch. On iPad, every room opens out into a wide painting, upright or sideways. A CAT, AND THINGS FOR IT TO WEAR Six companions, hand-drawn and animated. Focusing earns whiskers, and whiskers buy cat accessories and the monthly rooms. Pet the cat and it notices. WHAT YOU NEED TO DO, AND WHAT YOU DID A task list that stays in sync with your phone's own Reminders. A record of every session — hours, streaks, and the note you left about what you were working on. Sit Still Premium is an auto-renewing subscription, offered monthly or yearly at the price shown in the app. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in Settings › your Apple Account › Subscriptions.
