Events and to-dos
don’t get mixed into one list
Events are organized by time, while to-dos stay in an action list. Keeping them separate makes it clear what to start with today.
Small steps bring you
closer to the change you want
Both the days you kept going and the days you came back are recorded. Streaks, completion rates, and day-of-week patterns show how steadily you’ve kept it up.

Frequently asked questions
Are any features limited without an account?
The planner — events, to-dos, habits and cycle records — works without an account, and your records stay in this browser. Connecting Google Calendar or Google Tasks, and syncing across devices, need you to sign in.
If I make an account later, will my existing records carry over?
Yes. When you sign in, you’ll be asked whether you want to import the records stored in this browser into your account.
Do I have to use the cycle feature?
No. It’s off by default. The Cycle tab appears only after you turn it on in Settings or tap Show cycle on the Monthly calendar, and you can turn it off again anytime.
Does it work with Google Calendar?
You can connect Google Calendar and Google Tasks. Connecting is optional and you can disconnect at any time.
Are my period records sent to Google?
No. Even with Google Calendar or Google Tasks connected, period records are never sent to Google.
Can I use it on Android?
The Android app is coming soon. Until then, you can add the web app to your home screen and use it like an app.
Can I see my cycle and my schedule in one calendar?
Yes. Your cycle appears as a soft tint in the calendar, with events and to-dos layered on top.
How do I see my next expected period in the calendar?
Go to a future month and your expected cycle appears in a lighter shade. The Cycle screen shows your next expected period date.
Can I view my cycle while planning my schedule?
Yes. You can view your expected cycle while choosing dates, and add events directly from the calendar.
Can I manage my period and schedule in one place?
Yes. Events, to-dos, habits and your cycle are all in one place, with optional Google Calendar and Google Tasks syncing.
