Less scrolling, more living. Spool blocks doomscrolling, brainrot, and screen addiction at the source — by making you justify yourself before you scroll. Most screen time blockers don't work because they treat phone addiction like a discipline problem. It's not. It's a habit loop your brain is stuck in — a dopamine cycle reinforced every time you reach for your phone without thinking. Spool interrupts the cycle. Before any blocked app opens, you have to state your case to our AI. Use the same excuse too many times and Spool locks you out automatically. Built on cognitive behavioral techniques and behavioral research on attention and habit formation. WHY YOU'LL LOVE SPOOL - Understand your hidden triggers with daily AI insights - Track your phone addiction patterns over time - Discover when you reach for apps most (and why) - Instant app and website blocking that actually works - Schedule blocking windows for your weak hours - Lock in during deep work with custom focus sessions - Reflect on every excuse you've made and spot the loops - CBT-inspired techniques to break the dopamine cycle - Detox from doomscrolling, brainrot, and mindless scroll WHO IT'S FOR Spool is for anyone struggling with phone addiction, doomscrolling, or losing hours to TikTok, Instagram, Reels, YouTube Shorts, or X. Built for people who've tried Screen Time, willpower, and other app blockers — and want something that actually changes the habit, not just the limit. WHAT MAKES SPOOL DIFFERENT Other apps just block. Spool teaches you about yourself. Every excuse you make becomes data. Every reflection makes you more aware. Every blocked attempt strengthens the new habit. Reclaim your focus. Build a more intentional relationship with your phone. ————————————— Spool Full Access — Weekly Length: 1 week, auto-renewing Price: $4.99 USD / week Spool Full Access — Yearly Length: 1 year, auto-renewing Price: $44.99 USD / year Payment will be charged to your Apple ID account at confirmation of purchase.
