Cortex brings sleep sounds and a focus timer into one daily routine. Choose a sound for winding down, set your sleep timer, or start a focused stretch of work or study. No ads, no account, no sign-up. 40 SOUNDS FOR SLEEP AND FOCUS Explore 27 sleep soundscapes and 13 focus tracks. Soft piano, muted guitar, warm cello, low woodwinds and slow ambient textures give your evenings more variety. For work, choose lo-fi, acoustic music, gentle rhythms or a beatless reading background. Three focus tracks are built in and free. The other 37 tracks, including all sleep sounds, are part of Premium and download on demand. Once downloaded, they work offline. Wi-Fi is recommended for downloads. FIND YOUR NIGHTLY FAVOURITE Browse by category, save favourites and return to recent choices. The Downloaded view keeps ready-to-play sounds together. Listen to a 12-second preview of an unlocked, downloaded track before choosing it for your session. SLEEP TIMER, A SOFT FINISH Premium includes six sleep durations from 15 minutes to 2 hours. Your chosen sound repeats during the session and gradually fades to silence at the end, without an alarm. The 18 new sleep loops each contain at least three minutes of audio. A morning check-in lets you record how you slept. FOCUS AT YOUR OWN PACE Pomodoro 25/5, Long Focus 50/10, Short Sprint 15/3 and open-ended Flow are free. Track sessions, streaks and heatmaps.
