## What is TimeSpinner?

TimeSpinner is a calendar that places your events on a clock wheel. See what happens at each hour of the day as a pie chart. There are three wheels, Year, Month and Day, and the buttons above the wheel switch between them.

■ Pie chart schedule
The Day wheel follows a 24-hour clock, with a hand pointing to the current time. The Month wheel shows one month in a full turn, and the Year wheel shows one year. The Year view can also be shown as a grid.

■ Drag a tag to add an event
Save events you add often as tags. Drag a tag onto the wheel, and an event with the tag's duration is added where you lift your finger. Each tag has a name, duration, color and repeat setting. Drag an event on the wheel to move it, and drag its handles to change the start and end times.

■ Notes, URLs, alerts and repeat
Add notes and a URL to each event, and set up to two alerts. Repeat every day, every weekday (Mon–Fri), every week, every 2 weeks, every month or every year.

■ Home Screen widget
The widget comes in every size from small to extra large. Tap inside the widget's wheel to switch between Year, Month and Day.

■ Statistics
For each year, month or day, see the total time, trend, weekday and hour patterns, and a comparison with the previous period for each event.

■ Calendar Import
Show events from the Calendar app on your device on the wheel, including iCloud, Google and Outlook accounts added in Settings.

■ Write to Calendar
TimeSpinner events are written to the TimeSpinner calendar in the Calendar app. Events you edit, add or delete in the TimeSpinner calendar also change in TimeSpinner.

■ Sync across devices
Events and tags sync across devices logged in to the same account. Log in with an email address or with Apple.

■ Colors and display
Choose the background and dial colors. Show the next period in the passed part of the wheel, or dim the days that have passed.

Available in English, Japanese, Korean and Chinese (Simplified and Traditional).
