Hey Product Hunt - I'm Hiroto, a first-year software engineer in Japan. I built Nautilus because every focus app I tried was made for students cramming for exams, not working adults juggling a day job and side projects. Nautilus went live on the App Store this week (iOS 18+, free) - the public 1.0 after weeks in TestFlight beta. What makes it different: - OS-level blocking via the Screen Time API (FamilyControls) - not a gentle reminder. When you dive, your chosen apps are shielded and opening one shows a custom screen: "Diving now. Surfacing in N min." (You can still lift it from iOS Settings > Screen Time if you really need to - it puts distance between you and the temptation, it doesn't trap you.) - 3-second thought capture from the Dynamic Island or Lock Screen - the "oh, I need to do that" that hits mid-session gets caught without breaking focus, and comes back when you surface. - Auto dive-log - surface and your session is already a journal entry: depth, duration, and the thoughts you captured. No manual logging. The depth metric: you go deeper the longer you focus without reaching for a blocked app. ~50 minutes undisturbed = about 50m deep. It only ever increases - no streaks, no red badges, no guilt on a zero-minute day. Just honest data. I built this for myself first. What's the one thing that breaks your focus that no app has solved yet? Tell me below - I read every reply.
