## What is Kururi Clock?

Kururi Clock is a Pomodoro timer that quietly keeps you company while you focus.

Stuck at the very first step? Start with just 25 minutes. Using the baby-steps approach, break a big goal into small blocks of time and move forward one at a time.

WHAT IS THE POMODORO TECHNIQUE?
A time-management method that repeats a set of 25 minutes of focus and a short break of about 5 minutes. It began in the late 1980s, when Francesco Cirillo of Italy tried it with a tomato-shaped kitchen timer ("pomodoro" is Italian for tomato). Knowing when a session ends makes it easier to get started, and short breaks help you stay focused.

WHAT ARE BABY STEPS?
An approach that breaks a goal into small actions you can be sure to complete and moves forward bit by bit. Deciding "just this much today" lowers the barrier to starting and makes it easier to keep going.

FEATURES
• Tap the round button to start the timer. Choose 5, 15, 25, 30 or 60 minutes.
• You get a sound and a notification when it ends, even if the app is closed.
• A large, easy-to-read time display. Tap it to hide the date and show only the time.
• A 3D model that makes one full turn every 20 seconds helps you stay relaxed while you work.
• Swap in your favorite 3D data (STL, PLY, GLB, USDZ) to make it your own desk companion (paid version). Shown as a silhouette, or in color for PLY (vertex colors) and USDZ (material colors).
• Turn off auto-lock to keep the screen on — perfect for a desk or bedside clock.
• A soft, gentle design.
• Built-in help, available in Japanese, English, German, Spanish, French, Italian, Korean and Chinese (Simplified and Traditional).

FREE
Use every clock and timer feature with the included sample data: a whale (STL) and a moon (PLY, in color).

PAID VERSION (one-time purchase)
Load your own 3D data. This is a one-time purchase, not a subscription. All other features stay free.

SUPPORT DEVELOPMENT
You can optionally send the developer a tip in the app. Tips do not unlock any features.

ABOUT 3D DATA
• Files up to 50 MB can be loaded. For smooth display we recommend 10 MB or less and about 500,000 polygons. Please reduce heavy data first.
• If the model looks sideways or upside down, switch between Z-up and Y-up in Settings.

PRIVACY
No personal information is collected. Files you load stay on your device and are never sent anywhere.

PLEASE NOTE
• iPhone only (iPad is not supported).
• Keeping the screen on uses more battery and the device may get warm. For long use, we recommend keeping it on a charger.
