UrgeLock is built for people who want to stop turning to adult content, manage urges, and regain control of their attention, habits, and time. UrgeLock requires a subscription. Eligible new subscribers get a 3-day free trial. Because quitting isn't only about counting days. It's about what you do when the urge actually hits. UrgeLock gives you a complete set of tools to help you get through difficult moments, understand your patterns, stay accountable, and keep moving forward, one day at a time. WHEN THE URGE HITS Don't face it with willpower alone. Tap the Urge Button and immediately give yourself somewhere else to go. Breathe, reflect, make a commitment, play a quick mind game, write down what you're feeling, or talk to Locky. The goal is simple: interrupt the pattern and make your next choice easier. MEET LOCKY: YOUR AI RECOVERY COMPANION Sometimes the hardest moments happen when nobody else is around. Locky is your personal AI companion inside UrgeLock, available whenever you need to talk, reflect, find motivation, or work through an urge. BLOCK THE CONTENT THAT PULLS YOU BACK Make temptation harder to reach before the difficult moment arrives. UrgeLock's Content Blocker uses Apple's Screen Time technology to help restrict adult websites and lets you add sites you personally want blocked. TRACK EVERY DAY YOU TAKE BACK Watch your clean time grow from the moment you decide to start. Track your current streak, clean days, milestones, and activity. If you slip, record what happened, reflect on what led to it, and start again. No shame. No hiding the reset. Just information you can learn from and another opportunity to move forward. TURN PROGRESS INTO MOMENTUM Recovery can feel invisible. UrgeLock makes your progress something you can see. Unlock achievements, reach new milestones, complete daily commitments, build your streak, and watch small decisions add up over time. JOURNAL YOUR WAY Use private text and voice journals to capture thoughts, urges, wins, difficult moments, and the patterns you begin to notice along the way. TOOLS FOR THE MOMENTS THAT MATTER UrgeLock gives you more than a counter (subscription required): • Urge Button for difficult moments • Locky AI companion • Content blocking • Streak and clean-day tracking • 105 achievements and milestones • Daily commitments • Text and voice journaling • Guided recovery meditations • Breathing exercises • Focus and sleep sounds • Mind games • Articles and recovery resources • Relapse and trigger tracking • Activity summary YOU DON'T HAVE TO DO IT ALONE Join an anonymous community of people working toward the same goal.

We do not sell your personal data. Your private journal and voice notes stay on your device, and an optional backup is encrypted with a key only you hold.
