Brain Rot Control puts a pause between you and the apps you open without deciding to. When a protected app opens, a Screen Time shield lands first. You can stay out, or take a timed unlock — five, ten, or fifteen minutes that lock themselves back automatically. That single pause is the whole product. WHAT YOU GET - A shield before the app, not a report after it - Timed unlocks that re-lock on their own - Deep Detox: a stronger session for when you need the door shut - Bedtime, work, study, morning, and weekend windows with real hours and days - Brain Recovery: a score that moves when you stay out, finish a detox, or hold bedtime — never from a tap - A weekly recovery report: time reclaimed, opens prevented, longest detox, nights protected - Challenges built from what you actually did, not from streak theatre - Home Screen and Lock Screen widgets HOW IT WORKS Setup starts with a few questions about where your time goes, then builds a protection plan around them. After that you pick the real apps and sites with Apple's own picker, and the first rule goes live. You test it immediately: open one of the blocked apps and watch the shield appear. HONEST ABOUT THE LIMITS Screen Time settings always stay yours. Deep Detox makes leaving slow on purpose, but no app can stop you from changing Screen Time permissions in iOS Settings, and this one does not pretend otherwise. PRIVACY Your selected apps and recovery progress stay on your device. No account, no backend, no advertising, and no cross-app tracking. SUBSCRIPTION Yearly Pro includes a 3-day free trial. Monthly Pro is available without a trial. Everything above requires an active subscription. Payment is charged to your Apple ID account. Subscriptions auto-renew unless canceled at least 24 hours before the current period ends. You can manage or cancel your subscription in App Store account settings.

Most apps are designed to be opened without thinking. Cogio turns those moments into a daily cognitive workout. Every time you open a guarded app, Cogio steps in with a quick problem — math, logic, sequences, patterns. Solve it, and carry on to the app. It takes seconds. But those seconds add up to a sharper, more deliberate mind. Your brain is a muscle. Cogio is the gym. Most people solve 5–20 problems a day without even trying — just by going about their normal phone use. Cogio fits cognitive training into moments that already exist in your day, no extra time required. Who is Cogio for? Anyone who wants to stay mentally sharp without carving out extra time in their day. If you already pick up your phone dozens of times a day, you already have everything you need for a daily cognitive workout. What kind of problems? Mental arithmetic — fast calculation to keep your number sense sharp Logic — riddles and deductive reasoning Number sequences — pattern recognition and working memory Patterns — spot the rule, predict what comes next Visual memory & search — hold what you just saw, find what's different Inhibition — resist the reflex answer when your brain wants a shortcut Every problem is randomized, so your brain never gets to autopilot through the same one twice. How it works 1. Choose which apps to guard — Instagram, TikTok, YouTube, X, Reddit, or any app you open on autopilot 2. Grant Screen Time permission (Apple requires this for the guard to work) 3. Open a guarded app as you normally would 4. Cogio steps in with a problem — solve it in seconds 5. You're through — carry on to the app you opened Track your progress Cognitive fitness score — one number that grows with every rep Skill levels — watch your accuracy per category climb Daily solve streak — build a habit of consistent mental exercise Lifetime solves — watch the reps add up Cogio Pro Cogio is free to download. Cogio Pro unlocks the full experience, including guarding multiple apps, with monthly, annual (7-day free trial), and lifetime options. Payment is charged to your Apple ID account; subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Built for privacy Cogio's problem-gating runs entirely on your device using Apple's Screen Time API — no account required, and which apps you guard, your scores, and your settings never leave your phone. We use a standard analytics tool to understand how the app is used (like app opens and feature usage); it's never used for ads or to track you across other apps. Purchase and subscription data is processed by our payments provider to manage your subscription. See the App Privacy section on this page for exactly what's collected. Cogio uses Apple's Family Controls framework (the Screen Time API) for one purpose: to detect when you open an app you've chosen to guard, and to present the problem before you continue. It cannot see what you do inside other apps, read their content, or track your activity. Think before you scroll. Terms of Use: https://cogio.app/terms Privacy Policy: https://cogio.app/privacy
