Check your agenda, add tasks and meetings, update lists and log habits on iPhone without opening Chronos.
By Byte Size Labs · Updated 16 October 2026
Ask for anything in your own words: add or move tasks and events, find time, summarise your week or a project, start a list, add to your journal, tick something off and more. Use it whenever the other phrases don't fit.
Saying “What's on my agenda in Chronos” without a day tells you what's next.
A time in the phrase books the meeting for today. Any hour or half hour from 6am to 9pm works (“6:30am”, “1pm”, “8:30pm”). For another day, or a time like 4:15, leave the time out and tell Chronos when it is.
Chronos schedules the task straight away and tells you when it's on.
Shopping, grocery, packing and to-do lists each have their own “Create a … list” and “Add to my … list” phrases. Name several items in one go. For any other list, say “Create a list in Chronos”.
Chronos names your current or next task and waits for you to say yes before ticking it off.
Each also works with “with Chronos”. Your brief covers what matters today and anything at risk.
Say “Log”, then the habit's name. It doesn't have to be exact: “sleep eight hours” finds a habit called “Sleep 8hrs” (iOS 17 or later). With only one habit, “Log a habit” logs it without asking. Siri tells you your streak, or that today's target is already met.
Separately from Siri, Pro and Teams members can turn on a “Hey Chronos” wake word in the app under Settings › Voice. Say “Hey Chronos”, then talk to Chronos the same way as “Talk to Chronos” above. Say “never mind” or “that's all” to finish. It's off by default, and your iPhone shows its microphone indicator while it listens.
Open the app and sign in once. Siri uses that session from then on.
Everything except habit logging uses the Chronos Agent, which comes with Pro and Teams.
Turn it back on in the Chronos app under Settings › Voice.
Siri stops waiting after about 20 seconds. The request may still go through, so check the app.
Wait for the previous request to finish, then try again.
Check your connection and try again in a moment.
To stop Siri using Chronos, switch off Siri in the app under Settings › Voice.
