## What is Chaos Calendar?

Take your Time & Chaos or Chaos Intellect calendar with you — Chaos Calendar brings your Windows PC appointment data to iPhone and iPad, keeping everything in sync across your devices.

YOUR CALENDAR, YOUR PRIVACY
Chaos Calendar maintains an independent calendar database, completely separate from any other appointments or calendar program you have. Your event schedule stays private and is never shared with other apps without your permission.

FEATURES

  daily, weekly timeline, monthly calendar, or ongoing list
• Set an alarm on any event for a reminder before it starts
• Send or accept appointments via sharing
• Filter appointments listed using groups to stay focused on what matters
• Sync with Time & Chaos 10 or Chaos Intellect 10 on Windows through ChaosHost

REQUIREMENTS
Requires a ChaosHost account for cross-platform sync.
