The Problem

Multitasking Is Killing Your Productivity

Constantly switching tasks fragments your attention — every interruption pulls you away and takes time to recover.

⚠️

Context Switching

Every time you switch tasks, it can take many minutes to settle back into deep focus.

Costly switching

Mental Fatigue

Juggling multiple tasks simultaneously drains cognitive resources and increases stress.

Digital Distractions

Most of us reach for our phones dozens of times a day, breaking focus again and again.

The Science

40Hz Binaural Beats: What They Are

1

What a binaural beat is

Play two slightly different tones — one in each ear — and you perceive a third, slower "beat" equal to the difference. Deep Focus uses a 200Hz/240Hz pair, so you hear a steady 40Hz pulse.

2

Why 40Hz?

40Hz sits in the "gamma" band that researchers study in relation to attention and concentration. It's an active, evolving area of neuroscience — and the evidence on audio "entrainment" is still mixed.

3

A calm sound layer

However the science settles, a steady, unobtrusive soundscape can help mask distractions and signal "focus time" — so we include it as one tool among several, to try for yourself.

An evidence-based note: binaural beats are a real and active area of neuroscience research, but the evidence for cognitive or productivity benefits is still emerging and mixed. We offer Deep Focus as a calm tool to help you single-task — not as a guaranteed result.

Stays With You While You Focus

Two new ways to keep a session running your way — see the timer without unlocking, and keep your own music playing.

Features

Everything You Need to Stay Focused

Deep Focus combines a calm focus environment with intelligent app design to keep distractions out of the way.

📱

Lock Screen Timer

Your countdown lives on the Lock Screen and Dynamic Island as a Live Activity. Glance at the time remaining without unlocking your phone or reopening the app.

  • Live Activity on the Lock Screen
  • Dynamic Island on supported iPhones
  • Counts down in real time, even while locked
🎧

Play Your Own Music

Deep Focus layers its 40Hz soundscape on top of whatever you're already playing — Spotify, Apple Music, a podcast. Start a session without silencing your music.

  • Mixes with any other audio app
  • Keep your own playlist or podcast going
  • Binaural beats and ambient sounds blend in
🔒

App Lock

Add a gentle speed bump to leaving a session. If you switch away and come back, Deep Focus blurs the screen and asks for your PIN before you continue — a moment to think twice. (iOS does not let any app block switching outright.)

  • Blurs the app and asks for your PIN on return
  • 4-digit PIN, stored in the iOS Keychain
  • For a true lock, pair it with iOS Guided Access
🎵

40Hz Binaural Beats

Stereo audio that generates a steady 40Hz binaural beat — a calm, unobtrusive sound layer designed to help you settle into focus.

  • Pure 40Hz gamma wave generation
  • Adjustable volume control
  • Real-time frequency adjustment
🌊

Ambient Sounds

Layer a calming sound over your binaural beats to mask distractions and set the mood — pick what suits you.

  • Nature: ocean, waterfall, rain
  • Noise: white, pink, brown
  • Independent volume control
🔕

Focus Mode Reminder

When a session starts, Deep Focus reminds you to switch on Do Not Disturb so notifications stay quiet while you work. (iOS apps can't toggle system Do Not Disturb for you, so this is a nudge, not an automatic switch.)

  • A gentle prompt to turn on Do Not Disturb
  • Your audio keeps playing throughout
  • One tap away in Control Centre
⏱️

Customizable Timers

Choose session lengths that work for you: 20, 25, 30, 40, or 45 minutes. Perfect for Pomodoro technique or extended deep work.

  • Pre-set timer options
  • Pause & resume capability
  • Completion notifications
📊

Session Tracking

Monitor your progress with detailed statistics. See how many focus sessions you've completed and track your productivity over time.

  • Session history

FAQ

Frequently Asked Questions

Do I need headphones?

Yes! Binaural beats require stereo headphones or earbuds to work properly. Each ear needs to hear a different frequency for your brain to perceive the 40Hz difference. Ambient sounds work with or without headphones, but headphones provide the best experience.

Is it safe to use daily?

Binaural beats are simply sound — there's nothing invasive about them. As with any audio, keep the volume at a comfortable level. If you have a hearing or neurological condition, check with your doctor first.

Can I unlock the app during a session?

Yes, with your 4-digit PIN. The lock feature is designed to help you commit to focus, but you always have control with your PIN.

How long until I feel the effects?

It varies from person to person, and the research is mixed — so we won't promise a specific result. The best test is to try a session or two and notice whether the calm, single-tasking setup helps you focus.

Does it work for everyone?

Responses to binaural beats vary from person to person, and the evidence is mixed. The timer, App Lock speed bump, and a quiet single-tasking session help regardless — we'd suggest trying it for a week to see what works for you.

What are ambient sounds?

Ambient sounds are background audio you can layer over the binaural beats: nature options (ocean, waterfall, rain) and noise options (white, pink, brown). They help mask environmental noise and create a more immersive focus environment. You can adjust their volume independently or turn them off entirely.

Can I play my own music during a session?

Yes. Deep Focus mixes its audio with whatever you're already playing — Spotify, Apple Music, a podcast, anything. Start your music first, then start a session, and the 40Hz beats and ambient sounds layer on top instead of stopping it.

Does the timer show on the Lock Screen?

Yes. Each session runs as a Live Activity, so the countdown appears on your Lock Screen and, on supported iPhones, in the Dynamic Island. You can glance at the time remaining without unlocking your phone or reopening the app.

What's the pricing model?

Deep Focus is a one-time purchase with no ads, no subscriptions, and no recurring fees. Pay once, own it forever. We believe in transparent pricing - you get lifetime access to all features without any hidden costs.
