How it works Pick a session - Deep Work, Quick Focus, or Long Session - and press start. A warm-up period eases you in, then the timer begins. When you’re done, you’ll see how long you stayed focused. That’s it. No complicated setup, no overwhelming features. Track your progress See your focus hours for today, this week, and this month. Watch your streak grow as you build a daily deep work habit. Every session is saved locally on your device - your data stays yours. What makes Deep Session different Starts in seconds, not minutes No sign-up or onboarding walls No cloud sync, no servers, no tracking Designed to feel calm and quiet Works completely offline Dark mode that actually looks good Built for deep work Deep Session is inspired by the idea that the hardest part of focused work is simply starting.

Choose a Focus Profile, set a duration, and see whether each device is protected—without a vague all-green status hiding a problem. FOCUS YOUR WAY • Start 25, 50, or 90-minute sessions, or choose a custom duration. • Build Profiles for Deep Work, Study, Reading, and your own routines. • Block selected apps and websites on iPhone and iPad with Apple's Screen Time controls. • Use the free Mac companion to protect supported apps and websites. • Keep a session going with local rain, café, train, forest, wave, and other procedural sounds. ONE SESSION, HONEST STATUS Private iCloud sync carries your active session, Profiles, schedules, history, and verified Pro status between devices. OneFocus shows iPhone Protected, Mac Protected, Waiting, Needs Permission, or Offline separately, so you know what is actually happening. Existing local sessions and history remain useful offline. HISTORY THAT EXPLAINS YOUR TIME Review Today, 7 Days, Month, and All Time.

Verdict
The clearest difference is in-app purchases: Deep Session at none against OneFocus's 1. Deep Session also leads on iOS requirement (15.1 vs 17.0). On price, ads and device support there is nothing between them.
