Kiyo

A personal planner that gives events, to-dos, and habits a structure of their own. Your menstrual cycle appears alongside them only when you switch it on.

What is Kiyo?

Kiyo is a personal planner for laying out the day’s to-dos and schedules and keeping a steady record of your habits. The same records carry over between the web and the iOS app, and you can start using it right away without an account.

What sets Kiyo apart from other planners is that it does not treat events, to-dos, and habits as one kind of record. Events are about when. To-dos are about what. Habits are about the change you want to keep building. Kiyo gives each one the space it needs, while bringing together what matters today.

Three things, three shapes

Who is it for?

It is for anyone who wants events, to-dos, and habits organized in one place. Period tracking is an optional feature that is off by default, so if you never turn it on, it never appears anywhere on screen.

If you do want your cycle in view, it appears as a soft tint on the calendar and Daily screens, so you can keep it in mind while you plan the day. Kiyo does not decide your plans around your cycle for you. Instead it groups your records by phase, so you can see when your to-do completion was higher and your habits were easier to keep up — something to refer to as you understand your own rhythm and plan what comes next.

Period calculations and your next expected date

Turn the cycle feature on and log the day your period starts, and Kiyo calculates your next expected period and marks it on the calendar in a light tint. Flip ahead to next month and the expected cycle is already drawn in, so you can see where your next period falls while you book a trip or an important appointment.

All you have to log is the start date each month. Once records build up, the estimate switches from the average you entered at setup to the median of your recent cycles, so it better reflects your own pattern over time. If you would rather run a quick calculation first, try the period calculator — your last start date and your average cycle length are all it needs.

Discreet mode

So that nobody glancing over your shoulder can read the screen, Discreet mode hides every phase name and shows emoji only. Pick faces, weather, moons, or nature, or assign the emoji yourself. Turn it on in Settings > Cycle Syncing.

Accounts and data use

Signing in is optional. With an Apple or Google account, you can:

• Sync and back up your planner records across devices
• Google Calendar sync — bring calendar events into the app, and push events you create in the app back to your calendar
• Google Tasks sync — import your to-dos and sync completions and deletions back to Google

This data is used only to provide the planner features above. We do not use it for advertising and we do not sell it to third parties. See our Privacy Policy and Terms of Service for details.

Also in Kiyo

• Seven themes — Ink, Cream, Sage, Pine, Clay, Indigo, and Midnight for dark mode
• Daily and habit reminders — a notification at the time you set (app only)
• D-Day — the days left until a date that matters, at the top of Daily

What matters to us

No one gets through every day exactly as planned. Some days you miss a habit. Some days you don't want to do anything at all. Some days you get more done than you expected.

Kiyo records those days as they were, and shows you the stretches where you kept going. We think plans exist not to pack life tighter, but to make it a little simpler and easier to live with.

We're building Kiyo to make everyday planning feel a little easier and help you feel good about the changes you've made.
