About this app

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

YOUR CALENDAR, YOUR PRIVACY

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.
