## Version history (last 5 releases)

### 1.7.0 — 2026-07-23

This update gives Slumbertone a fresh coat of polish and a stronger foundation:

* A refreshed look on iOS 26, with Apple's new Liquid Glass design across cards, controls, and the timer sheets, plus new raised play and stop buttons that follow your selected sound's color.
* Upgraded to the latest app framework for better performance, reliability, and compatibility with the newest devices.
* Cleaned up under the hood for a leaner, faster app.

As always: pick a sound, set your timer, and sleep well.

### 1.6.0 — 2026-05-27

Slumbertone 1.6.0 — Sleep softer.

• Brand-new native time pickers for Custom Duration and Wake At — the familiar iOS spinner, polished for low light.
• Slumbertone now steps aside gracefully for phone calls and resumes when the call ends.
• Music, Podcasts, and your other audio apps regain focus the moment Slumbertone stops.
• Smoother fade-in every time you press Play.
• Cancelling a sleep timer cleanly aborts any in-flight fade-out.
• Quicker sound switching from the home wheel.
• A handful of under-the-hood fixes for a more reliable night.

### 1.5.0 — 2026-04-25

Slumbertone has a brand new look. The interface has been completely redesigned with a clean, modern aesthetic — smoother gradients, refined glass cards, and a background that shifts color to match whatever sound is playing.

Sound selection is now a smooth scroll wheel right on the main screen — no more tapping into a separate picker. The play button now toggles to Pause while audio is running, and both timer pickers have been rebuilt as scroll wheels for a much more natural feel.

Same seamless loops, better everything else.

### 1.4.2 — 2025-09-14

What’s New (1.4.2):
	•	Resolved “Unable to start audio” on some devices after updating iOS.
	•	Rebuilt all noise tracks for seamless looping—no clicks or surges at the loop point.
	•	Tuned levels so Brown Noise is clearer at normal volume.
	•	Stability improvements for background playback and lock-screen control.

### 1.4.1 — 2025-09-11

Thank you for using Slumbertone! Here's what's new in this version:
* Louder and clearer brown noise
* Cleaner and more seamless transitions during looping
* Bug fixes and performance improvements
