Write your day, your way

Tap and start typing. Each day is a page you build from blocks: writing, checklists, sticky notes, pictures, voice notes and drawings. Everything saves by itself a moment after you stop.

  • Bold, italic, headings and lists as you type
  • Voice notes up to 5 minutes, for when it's easier to say it
  • Draw with a pen, highlighter and shapes
  • Drag blocks into any order, and undo anything
  • Swipe sideways to move between days

A gentle check-in

Beside your page sits a quick daily check-in. Pick how you feel, note your sleep, rate your depression and anxiety, and tap where it hurts on the body map. Fill in as much or as little as you like.

  • Show only the sections you want, in the order you want
  • Health tools, a period tracker and a transition section, all off unless you switch them on
  • Medications, fitness, blood pressure, weight, tasks and more
  • Unfinished tasks offer to carry over to tomorrow

See how you've been doing

Every check-in builds a picture over time. Insights turns your days into charts and a colourful year in pixels, and the calendar shows every day in the colour of your mood.

  • Mood over time and by weekday
  • Depression and anxiety on one chart, with a week average
  • Patterns, like whether your anxiety is higher after short sleep
  • Sleep and pain charts, and a map of where it hurt most
  • Memories of this day in years gone by, and search across everything

Count the days that matter

Days since counters tick up live from a moment that matters to you, or count down to something coming up. Each one gets its own colour, and you can put them on your home screen.

  • Years, months, weeks and days, or just the total days
  • Home screen widgets that keep ticking even when Kaydence is closed
  • A little celebration for your first week, every year and more, with Kaydence's own chime

Private by design

Kaydence is made for the things you'd never post online. It has no accounts, no adverts and no analytics, and it never sends your diary anywhere.

  • Kaydence has no permission to use the internet
  • Your diary, pictures and voice notes stay in Kaydence's private storage on your phone
  • It's left out of your phone's cloud backup, so it never syncs anywhere by itself
  • A backup only leaves your phone when you choose where to save a copy
  • Kaydence Plus goes through Google Play, and Kaydence never sees your payment details

Kaydence's dark theme showing today's page
Not medical advice. Kaydence is a diary, not a medical app. Its health and period tools are for your own notes, and cycle guesses must never be used as contraception. Patterns only show what you've logged. They aren't a diagnosis, just a starting point for a conversation with your doctor. If things feel too much, Samaritans are there day or night on 116 123 (UK), free.

Coming soon to Google Play

Kaydence is in testing now. It'll be free to download for Android phones and tablets running Android 7.0 or later.

Questions

Is Kaydence free?

Yes. Kaydence is free to download, and writing, check-ins, pictures, voice notes, drawings, the calendar, search, reminders and backups are free for good. Kaydence Plus is an optional one-time payment that unlocks extras. There are no adverts and no subscriptions.

Where is my diary kept?

On your phone, in Kaydence's own private storage. It isn't uploaded anywhere, it's left out of your phone's cloud backup, and Kaydence doesn't even have permission to use the internet. A backup only leaves your phone when you save a copy somewhere yourself.

What happens when I get a new phone?

In Settings, Backups, tap Back up now and save a copy somewhere you can reach from the new phone, such as a cloud drive app or your computer. On the new phone, install Kaydence and restore that backup. If you bought Kaydence Plus, tap Restore purchase on the Kaydence Plus page while signed in to the same Google account.

Does Kaydence need the internet?

No. Kaydence has no internet permission at all. If you buy Kaydence Plus, the Google Play Store app on your phone handles the payment and tells Kaydence it's unlocked.

Can I lock Kaydence with a password?

Not yet. A lock with fingerprint or face unlock is planned for a later version. Until then, your phone's own screen lock keeps Kaydence private.

Is there an iPhone version?

Not yet. Kaydence is coming to Android first.

I found a problem or have an idea.

Lovely, please share it! In Kaydence, go to Settings, Help and feedback. Report a problem or suggest a feature opens an email to kaydee@kaydee.codes, and Make a bug report saves the app's private logs so you can attach them if you'd like. They never contain anything you wrote.
