Description
Focus and sleep sounds that get out of the way and let you work.
Pulse Lab is a minimal, distraction-free white noise and focus sounds app. Isochronic tones and high-quality color noise — white noise, pink noise, and brown noise — for concentration, study, relaxation, and sleep. No playlists to scroll, no feeds, no accounts. Pick a session, press play, and get to work.
Download your sounds once and play them offline forever.
π§ WHAT'S INSIDE
- Isochronic tones across a range of frequencies, from slow and steady to alert - White, pink, and brown noise to mask distractions and steady your attention - Long-session playback that stays running through hours of focused work - Real-time audio visualization - Works offline once downloaded — no streaming needed during a session
π§ MADE FOR FOCUS AND CALM
- Deep work sessions and coding sprints - Studying for exams, certifications, and long reading - Writing, designing, and creative flow - Meditation and mindfulness breaks - Winding down and drifting off to sleep with steady white noise
π¦ OFFLINE AND DATA-FRIENDLY
- Download sound packs once, play them offline forever - Wi-Fi-only download option so you never burn mobile data - No streaming, no buffering, no interruptions mid-session
π INTENTIONALLY SIMPLE
- No accounts to create - No social features, feeds, or recommendations - No clutter — just the sounds and a play button - Optional upgrade removes ads for uninterrupted sessions
π THE UPGRADE
Most focus and sleep sound apps lock everything behind a monthly fee. Pulse Lab doesn't. A single purchase removes ads for good — nothing recurring, nothing to cancel later.
π ABOUT YOUR DATA
No account, no profile, nothing to sign up for. The free version shows ads through Google AdMob, which uses an advertising ID, and anonymous crash and usage reports through Google Firebase help me fix what breaks. That is the extent of it — nothing about which sounds you play or when goes anywhere.
Headphones recommended for the full isochronic effect.
Whether you need white noise to block out an office, focus sounds for a deep work session, or calm audio to fall asleep to, Pulse Lab is built to get out of the way and let you do the work.
Recent changes: A calmer Pulse Lab.
• New look — deep navy and teal replace the old red-on-black. Much easier on the eyes during a late session. • New app icon. • We're now just Pulse Lab. • Clearer text everywhere. Several labels were hard to read on dark backgrounds; every one has been checked for contrast.
Same one-time upgrade. Still no subscription, still works offline.
