What's New in Chaos Calendar
1.10
September 5, 2026
Link an appointment to the people it involves. Tap the new Linked Contacts field when you add or edit an appointment and pick one or more people from Chaos Contacts. Their names then appear on the appointment, each with a link to the full contact record and to every appointment you've had with them. When did you last meet? When was that last doctor's visit? The answer is one tap away. Requires Chaos Contacts (also updated)
