XIU the puppy asleep on a green cushion under a starry night sky and a crescent moon

It's okay to rest today

The mood diary where even a rest counts

Try it

Tap one face, just like in the app, and XIU answers. If you need a breather, rest with XIU for ten seconds.

How are you feeling? Just tap one.

Just for practice: nothing you pick here is saved or sent anywhere.

Bosong’s rest screen: XIU asleep on a cushion under the night sky, with a button to start breathing

It’s okay to pause for a while

On days you’d rather not name a feeling, tap “Rest day” once. You can also breathe with XIU for a minute. A day of rest still counts as a day.

Bosong home screen: a just-one-tap card with a few XIU faces, and this week’s calendar

Today's feeling, just one tap

Tap one face on the home screen and it’s saved. On days you want more, pick up to five feelings, how strong each one is, and a few words.

The screen after saving: XIU holding a book, a speech bubble, and a card with the feelings you just saved

Save it, and XIU has a warm word for you

After you save, XIU says a few words, celebrating with you on bright days and keeping it calm and gentle on heavy ones.

XIU’s weekly letter: the three feelings picked most often and a note about a rest day

Every Sunday night, XIU writes you a letter

When the week ends, a letter from XIU arrives on the home screen. It mentions the feelings you picked most and your rest days. No scores, no grades.

Stats screen: what XIU noticed this month and a bar showing the mix of feelings

Look, your heart has its own rhythm

XIU tells you, like a little story, how days of the week, tags and rest days line up with your mood. Everything is worked out on your device.

Bosong home in dark mode: two of today’s entries and the calendar on a navy night sky

Cozy as the night sky

Dark mode is a navy night sky with faint stars, so writing late at night stays easy on the eyes.

XIU’s 24 faces

Each of Bosong’s 24 feelings has its own XIU face. Hover or tap to see its name.

Small, and safe to lean on

  • Entries stay on your device, backups are end-to-end encrypted

    Every core feature works without an account. Even with Plus backup on, entries are encrypted on your device first, so not even XIUSoft can read your diary.

    Read the Privacy Policy

  • Rest and breathing

    A rest day takes one tap, and XIU can breathe with you for 1, 3 or 5 minutes. Bosong cares about your rhythm, not streaks.

  • Widgets and Apple Watch

    Log a feeling straight from Home Screen and Lock Screen widgets or Apple Watch, without opening the app.

If your store offers a free trial, it shows it before you subscribe. There is no trial from our side and no charge without your store’s confirmation. Bosong Plus is not offered in some countries and regions (currently the European Economic Area and the UK); the free features work there just the same.

See you on Android and Windows

Bosong is on Google Play and the Microsoft Store. The other button will work as soon as the App Store lists the app.

Frequently asked questions

Do I need an account?

No. Recording, looking back, stats, the lock, reminders and export all work without an account. You sign in (with Apple or Google) only when you turn on Bosong Plus.

Can XIUSoft read my diary?

No. Without Plus your entries never leave your device. With Plus they are encrypted on your device before upload, and only your recovery key can unlock them. We see encrypted pieces, sizes and times, never feelings, dates or text.

What happens if I lose my recovery key?

Your entries on your current devices are fine. But a backup can only be restored on a new device with the recovery key, and nobody, including us, can recreate it. Keep it somewhere safe (the app shows it under Settings).

What happens when my Plus subscription ends?

Everything on your devices stays and keeps working for free. Your encrypted backup is kept for 90 days so you can restore it, then deleted. Sync stops until you subscribe again.

I already have a XIUSoft account from LiveSSH.

You can use the same account. Bosong data and LiveSSH data are separate; you can delete only your Bosong data, or the whole XIUSoft account (which also removes your LiveSSH data). See Support.

Is Bosong a therapy or medical app?

No. Bosong is a diary, not a medical service, and it does not diagnose or treat anything. If you are struggling, please reach out to someone: the Safety page lists crisis lines.

Why does a rest day count?

Because some days you don’t want to name a feeling, and that’s okay. Bosong values rhythm over streaks: a rest day keeps your rhythm instead of breaking it.

A letter from XIU

To you, who came all this way,

Hi, it’s me, XIU. How was your day? You don’t have to answer.

Bright days, so-so days, heavy days: I’ll welcome them all with a soft wag of my tail. Resting days count too.

Tonight, I hope you have a warm cup of milk and somewhere cozy to rest. See you soon!

Love, from under a cozy blanket — XIU
