How it works
Three steps.
- 1
Choose what is read
Allow calendar access and pick the calendars. On iPhone that is anything in Apple Calendar; on Android, the calendars on your phone. Their events come in as fixed.
- 2
Plan around them
Tasks and goals are placed in the room that is left. Nothing is put on top of an event.
- 3
See it in your calendar
The plan you confirm is written into a calendar of its own, named “TimeLoop”. Show it or hide it like any other.
Work
TimeLoop
In detail
What it does for you.
Your events are not rewritten
TimeLoop does not move or change an event it has read. To change one, change it in your calendar and TimeLoop follows.
A change comes back as a question
Move a TimeLoop block in your calendar app and TimeLoop notices. It asks whether to replan the rest or keep the plan as it was.
Reminders, both ways
On iPhone, iCloud Reminders without a time come in as tasks and can be given one. Done in one place is done in the other.
Google, with guests
Connect Google Calendar and events come in with their video links and guests. An event you give a Meet link or guests goes out to Google and follows every change.
What “two-way” means here, exactly
In: the events of the calendars you choose. Out: your confirmed plan, into the “TimeLoop” calendar, kept up to date as the plan changes. That calendar lives with the rest of your phone’s calendars, so the plan appears in every app that shows them.
TimeLoop does not write into your other calendars and does not edit events it did not make. The one exception is Google, and only when you ask: an event you create with a Meet link or with guests is added to your Google Calendar, so that Google can send the invitations.
A preview is only a preview. Nothing reaches your calendar until you have confirmed the plan.
Which calendars work
On iPhone: Apple Calendar, with every account you have added to it, such as iCloud, Google, Outlook or Exchange. On Android: the calendars on your phone. On either, Google Calendar can also be connected directly.
Outlook and Exchange are read through the calendar accounts on an iPhone. There is no direct Microsoft connection. iCloud Reminders are an iPhone feature.
Free or Pro
Calendar and Reminders sync are free. So is planning around your events by hand. Having the plan made from a sentence is part of TimeLoop Pro.
Questions
Asked before you asked.
Which calendars does TimeLoop read?
The ones you choose: on iPhone anything in Apple Calendar, including Google, Outlook and Exchange accounts added there; on Android the calendars on your phone. Google Calendar can also be connected directly.
Where is my plan written?
Into a separate calendar named “TimeLoop”, so your own calendars stay as they are. You can see and hide it in any calendar app on your phone.
What happens when I move something in my calendar app?
If it is one of your own events, TimeLoop reads the new time the next time it syncs. If it is a block TimeLoop wrote, TimeLoop asks whether to replan the rest or keep the plan as it was.
Does it work with Outlook?
On iPhone, through the Outlook or Exchange account you have added to the phone’s calendar: those events are read. There is no direct Microsoft connection.
Is calendar sync free?
Yes. Calendar and Reminders sync are part of the free version.
