Fixed sleep sounds staying faded out after a gentle wake-up — playback now returns to full volume for your next session. Improved reliability of tip purchases so they're credited correctly every time. Various stability and reliability improvements. ### 1.3.2 — 2026-06-14 Bug fixes and improvements Fixed an audible pop/snap at the end of the gentle sleep timer fade-out Sleep streak now correctly counts sessions that start just before midnight Live Activity timer no longer stacks if you stop and restart audio Sleep timer changes now reflect immediately in the player Stability and performance improvements ### 1.3.1 — 2026-05-06 v1.3.1 Under-the-hood code cleanup and stability improvements. No features were added or removed — the app looks and behaves exactly the same. Internal architecture was reorganized to make future updates faster and more reliable. Also updated support and privacy policy links to point to the correct pages. ### 1.3.0 — 2026-05-02 Under the hood security improvements to keep your data safe: Sensitive app data is now obfuscated in the binary, making the app more resistant to static analysis Added jailbreak detection with a non-blocking notice if a compromised device is detected Purchase and sleep log screens are now blurred when the app is backgrounded or a screenshot is taken Hardened release build configuration for a smaller, faster binary ### 1.2.0 — 2026-04-29 This update brings major reliability improvements and a few thoughtful new touches. Sleep & wake-up timers Gentle wake-up fade now works correctly when your screen is off — previously the fade could freeze and audio would keep playing. Sleep timer is more reliable under heavy system load, so it fires close to the time you set. Your timer length and gentle wake-up settings are now remembered between launches — no more reconfiguring every night. Added a fade duration picker (30 / 60 / 90 / 120 seconds) for gentle wake-up. Audio quality Fixed a bug where stopping playback during a fade could leave your mixer sliders stuck at low volumes the next time you opened the app. Audio chains now rebuild correctly when switching between speaker, AirPods, and Bluetooth devices — no more thin or metallic reverb on 48 kHz outputs. Added headroom to prevent harsh clipping when all three mixer sliders are pushed to maximum. Smoother fades — eliminated a small click that could occur if you adjusted a slider mid-fade. Driftless now gently ducks other audio when it starts, instead of competing with it. When you stop Driftless, other audio apps (Spotify, Apple Music, podcasts) will now resume automatically. Siri & Shortcuts Premium sounds are now properly gated behind your subscription when launched via Siri or Shortcuts. Siri intents handle the "app not running" case more gracefully and no longer lose sleep sessions. Sleep log & home screen Sleep timer countdown is now visible on the home card, not just inside the player sheet. Lock-screen artwork renders faster and uses three distinct wave colors. Improved VoiceOver labels on preset chips. Plus a number of internal fixes for better reliability and performance. Thank you for using Driftless — sleep well. ## More apps by Hrdlicka Apps LLC - [DebtDown](https://appshunter.io/ios/app/debtdown/id6760519735) - [MedMinder: Medication Tracker](https://appshunter.io/ios/app/medminder-medication-tracker/id6761089534) - [TorqueVault](https://appshunter.io/ios/app/torquevault/id6767338154) All apps by Hrdlicka Apps LLC: https://appshunter.io/developer/1896342974 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
