For the hours you spend studying or working alone. While you dive, the apps you chose truly won't open. Exams, certifications, deep work included.
Nautilus folds three things into one action: dive.
REAL BLOCKING, AT THE OS LEVEL
Tap to dive, and the apps you chose (social, YouTube, etc.) are shielded on the spot via Screen Time. Not a reminder — while you're diving, those apps genuinely won't open. Block sets change per focus type (e.g. Reading vs. Coding).
DUMP A DISTRACTION IN 3 SECONDS
A stray "I need to do that" mid-session? Jot it down from the Lock Screen or Dynamic Island in about 3 seconds, without leaving focus. Everything you dumped is waiting for you when you surface.
SURFACE, AND IT'S ALREADY A JOURNAL
When you surface, that session becomes a log entry automatically — what you dove into, how long, what distractions you dumped. No manual logging.
DESIGNED FOR ZERO GUILT
No red badges. A zero-minute day isn't punished. "Depth," the number that reflects your focus quality, only ever goes up.
Blocking relies on the device's Screen Time framework.
Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
If you start without choosing any apps, other apps are now blocked while you dive.
