THE ARC DIFFERENCE Arc doesn't just block apps - it redirects your attention with a powerful three-part system: - Session Limits: Automatic breaks when a session has reached the set limit. No more unintentional doomscroll sessions. Daily limits are not helpful when the problem is getting sucked into the scroll hole and not realizing it. That's why we built session limits! - Smart Nudges: Gentle reminders about your to-dos while you scroll - Integrated To-Do Lists: Track what really matters, all in one place - Advanced Analytics: Track every session with precision. See exactly when you close apps yourself (exits) vs. when the timer saves you (lockouts). Discover your most addicting apps through unblock tracking, identify your best and worst self-control patterns, and get AI-powered recommendations tailored to YOUR behavior. No more guessing where to improve, the data shows you exactly which apps need stricter limits, where you're building great habits, and actionable steps to reduce your screen time based on real patterns, not generic advice or behavior patterns. HOW IT WORKS Select your distracting apps (Instagram, TikTok, Twitter, etc.) Add your daily tasks and goals Get Nudged with your to-do tasks when you're mindlessly scrolling Session Limits create automatic breaks after extended sessions Watch scrolling turn into productivity BUILT FOR YOUR LIFESTYLE Set your bedtime to switch from productivity Nudges to Sleep Reminders. Arc adapts to help you make better use of your time all day long. PERFECT FOR: People who unconsciously doomscroll and want to stop Professionals who lose focus to social media Students procrastinating on assignments Anyone who wants to build healthy daily habits Scroll Goblins People tired of feeling guilty after doomscrolling START SEEING RESULTS Reclaim hours of your day Complete the tasks you've been avoiding Track scrolling habits through intelligent insights Build habits that stick Rebuild a healthy relationship with social media Feel accomplished, not guilty Download Arc and turn scrolling into productivity.
