The app blocker that talks to you like a friend, not a drill sergeant

Thoughtful messages instead of cold "BLOCKED" screens. Progressive accountability when you need it. Quick access for emergencies. Focus that respects your intelligence.

Conversational blocking that adapts to you

Messages escalate based on your behavior. Tier 1 is gentle. Tier 2 is reflective. Tier 3 is honest.

Tier 1: Check-in

Each time you close this screen, the habit gets a little weaker.

A gentle, supportive nudge

Tier 2: Conversation

Take a breath. What were you doing before you picked up your phone?

Reflective questions that prompt self-awareness

Tier 3: Full support

That's 15 times today. That's a lot of energy.

What would actually help?

Honest, compassionate support

Because life happens: Quick Disable

Need to check an urgent work message? Waiting for an important call? Quick Disable lets you bypass blocking for 5, 10, or 15 minutes.

  • Limited to 1x per day (or 2x per week, your choice)
  • PIN-protected
  • Automatically re-enables when the timer expires

We're honest about this: Jublu isn't unbreakable. It's thoughtful. For emergencies, you have an escape hatch. For everything else, you have accountability.

Everything you need for focused work

Blocking groups with smart commitment

Scheduled groups auto-activate. One-time groups for timed sessions. Manual 24/7 groups with a 30-minute commitment lock to prevent impulsive deactivation.

53 messages across 7 emotional tones

Supportive, empathetic, encouraging, curious, reflective, grounding, direct. Messages vary so you never see the same one twice in a row.

De-escalation rewards restraint

Resist for 20 minutes, drop a tier. 90 minutes, back to tier 1. 6+ hours, full reset. The only blocker that gets gentler when you show self-control.

Block distracting websites too

Works in Chrome, Firefox, Samsung Internet, and DuckDuckGo. Block websites the same way you block apps. Same conversational approach.

Daily focus insights

Focus time protected, strongest group, streak, top blocked apps, and most-used apps from your device. Understand your patterns without judgment.

Notification interception

Blocks notifications from blocked apps, not just the app itself. Stored and delivered when your session ends. No FOMO, no interruptions.
