dpli creates real-time, evolving spatial soundscapes for ADHD focus and deep work — generated live on your device, never played from a loop. Unlike standard noise apps that replay prerecorded tracks, dpli synthesizes every layer in real time. Sound sources can move through space, shift in intensity, and modulate independently, creating an immersive background that stays dynamic throughout your session. BUILT FOR FOCUS Choose a preset based on what you need: • SHIELD — A steady spatial soundscape designed to mask conversations, office noise, and sudden distractions. • FLOW — Moving, asymmetric layers that create an engaging background for writing, coding, studying, and deep work. • CLARITY — Steady, precisely layered noise that masks distractions and creates a clear background for writing, coding, studying, and deep work. • IGNITION — Designed for ADHD brains or anyone needing a strong push into active focus. An energizing white-noise field with dual-rhythm pulses and airy blue-noise sparkle that drives alertness and mental speed. • RELAX — A heavy brown-noise blanket with two pink streams drifting slowly around your head — eases you into deep physical relaxation while staying awake. Good for winding down, tension release, or a mid-day relax. • RESET — A still, dark cocoon with a slow warm breath that gently sways around you — shifts the mind from stress into rest. Best for 10–20 minute breaks when you feel wound up or anxious. MORE THAN COLORED NOISE Brown, pink and white noise generators are included for free. They are also the building blocks behind dpli’s layered presets, where position, movement, modulation, and frequency balance work together to create a richer listening environment. GENERATED, NOT STREAMED • No prerecorded audio files • No repeating MP3 loops • Real-time synthesis on your device • Spatial movement and independent modulation • Works offline with no account required PRIVATE BY DESIGN Your sessions stay on your device. dpli does not stream audio, require an account, or collect listening data. MADE FOR THE APPLE ECOSYSTEM Use dpli on iPhone, Mac, and Apple Watch. Start a session wherever you work, study, travel, or need a more controlled acoustic environment. dpli is a focus and sound-masking tool. It is not intended to diagnose, treat, or cure ADHD or any other medical condition. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

About

Ambient Timer

Features
Read full description

A timer that creates space — for stillness, and for deep focus. Paired with field recordings and ambient film — crafted by a single artist, not a sound library. Sounds and visuals by Chisato Ohori, whose work has been exhibited at Kunstpavillon, a historic contemporary art gallery in Munich. Set the ring. Press play. Let time pass. Optionally, pair your session with field recordings or ambient film — or keep it in silence. When the timer ends, a break mode continues the same atmosphere, so the transition from focus to rest feels natural. A minimal ring interface. A gentle bell to close each session. And a record of every session, quietly accumulating over time. The timer, sound selection, and session history are free. Field recordings and ambient film are available with Unlimited — a one-time purchase of $2.99.
