### 5/5 — 좋다 싸다 깔끔하다

*2026-10-22*

다른앱보다 훨씬 낫다

## Version history (last 5 releases)

### 20261022.1.0 — 2026-10-22

See how many seconds are left in each inhale, hold, and exhale. You can turn it off in Settings.
The flower sits a little higher so the countdown is easy to read.
Now available in Italian.

### 20261015.1.0 — 2026-10-15

We removed all ads.
Meet Plus, a one-time purchase. Breathing guidance keeps going with the screen off, and you get every ambient sound, your own breathing pattern, the Apple Watch app, and widgets.
If you were already using Deep Breath, you keep the Plus features for free.
Settings are simpler and redesigned.

### 20260810.1.0 — 2026-08-10

Vibration now breathes with you. It swells as you inhale and fades as you exhale. Prefer something simpler? Switch to Minimal in Settings for single taps.
Apple Watch now guides you the same way your iPhone does, so once you learn one, you know both.
The Watch start screen fits on one page. Tap the orb to begin.
During a session, the orb sits at the center of the Watch screen and the end button no longer covers it.
In Guide Mode, you can return to the normal screen without ending your session.

### 20260717.1.0 — 2026-07-18

New: Apple Watch app. Breathe right from your wrist, with haptic guidance that keeps going even when the screen is off. Start a session with one tap from a watch face complication, and choose any length including unlimited.
Redesigned history with a monthly calendar and weekly rhythm.
New Guide Mode dims the screen so you can breathe with your eyes closed.
Improved vibration guidance.

### 20260518.1.0 — 2026-05-18

The widget has a fresh new look — frosted glass background and larger circular buttons for a cleaner feel.

Bug fixes
• Fixed an issue where chaining quick-start sessions from the widget would not restore the original session duration.
• Fixed an issue where toggling sound or vibration during a session could cause the session duration to reset after restarting the app.
