## What is Rubato?

Rubato is a daily planner that stacks your events vertically and lets you clear them from the top. Instead of pinning everything to a time, you stack them in order.

• A plan that flows
Stack what you want to do and it lines up from the top. Run late and everything after shifts; finish early and it moves up. You always see the whole day. Meetings and appointments become "fixed-time" events, and flowing events split around them.

• Stack and clear
Tap a frequent event in the History palette to stack it, or drag it into place. Complete it and it bursts away; the next one becomes current. Completion sounds and haptics are designed in-house.

• Usual
Rubato predicts what usually comes next, based on the time of day, the weekday, and what came before, and puts it first in the palette. It gets smarter as you use it.

• Your day ends when you sleep
Past midnight, the timeline keeps counting: 25:00, 26:00. Night owls' days stay in one piece.

• Live mode
The current time stays near the top, with only the current event and the next one shown large. Insert a break or a gap with one tap. Notifications arrive when an event starts, 10 minutes before a fixed-time event, and at the planned end.

• Works with your calendar
Events from your iPhone calendars (including Google) appear in the header; tap one to place it at a fixed time. Mark an event "Show in Calendar" and it's written to the calendar you choose, follows the flow as it moves, and settles into the actual time when completed. Subscribe to calendars by URL (iCal).

• All-day events and to-dos
Add all-day events and undated to-dos to any day. Tap a to-do to finish it; unfinished ones carry over to tomorrow. Place them on future days from the month view.

• iPhone and Mac
On Mac, Rubato lives in the menu bar and can be pinned as a standalone panel. It syncs through iCloud. There's no server: your data stays in your own iCloud.

• Pricing
Free to download. Try every feature free for 14 days (started by a ¥0 in-app purchase; it isn't a subscription and you'll never be charged automatically). To keep going, a single one-time purchase (¥2,200 in Japan; local price shown in the app) unlocks Rubato on both iPhone and Mac, forever. After the trial, viewing, completing, and syncing keep working.
