Stop doomscrolling on autopilot. Most apps are designed to be opened without thinking. Cogio turns those moments into a daily brain workout.

Every time you open a guarded app, Cogio shows a quick problem: math, logic, patterns, memory or focus. Solve it and the app opens. About 10 seconds each.

You pick up your phone around 80 times a day. One problem each time is 80 hours of brain training a year, with no time set aside.

Your brain is a muscle. Cogio is the gym.

Not just another app blocker
Hard blocks get switched off. Cogio doesn't lock you out. It puts a beat of real thought between the urge to scroll and the feed, so you decide whether to keep going, and your brain gets a rep either way. It's brain training built into the phone habits you already have.

Challenge your friends
Just solved something fast? Send it. Your friend gets the exact same problem in their browser, no app needed, and sees whether they beat your time. They can send one back. It never ends.

Circles
Start a circle with your family, friends or office and see who solves the most each week. One invite link, no sign-in, no strangers, no global leaderboards. Resets every Monday, so last week's champion has to earn it again.

What kind of problems?
- Mental arithmetic: fast calculation.
- Logic: deduction, set membership, odd one out.
- Sequences: number patterns and working memory.
- Pattern recognition: Raven's-style matrix reasoning.
- Inhibition: Stroop-style focus and impulse control.
- Visual memory and visual search: recall and compare what you just saw, find the match.
- Ordered tap: speed and sequencing.

Problems are generated from a bank of over 150,000 stems, so your brain never autopilots through the same one twice. Like brain games, but built into your day.

How it works
1. Choose which apps to guard: social media, video, news, or anything you open too often.
2. Open a guarded app as you normally would.
3. Cogio shows a problem. Solve it in seconds.
4. The app opens and you're on your way.

Who is Cogio for?
Anyone who wants to cut down on doomscrolling and screen time without deleting their apps, and anyone who wants a daily mental workout without carving out extra time. If you already pick up your phone dozens of times a day, you already have everything you need.

Track your progress
- Daily streak and total problems solved.
- Solve rate and time per category in your cognitive profile.
- Weekly circle standings and your challenge history.

Built for privacy
No account required. Cogio works without ever asking who you are. Your guarded apps, problem history and scores stay on your device. If you join a circle, only your first name, the circle name and your weekly solve count are stored so other members can see them; leave the circle and they're deleted. We use a standard analytics tool to understand broad usage patterns; it's never used for ads or to track you across other apps. Purchases are processed through Google Play and our payment provider to keep your Pro access working.

Accessibility Service disclosure
Cogio uses Android's Accessibility Service to detect when you open a guarded app so it can present the problem gate at the right moment. This is the only way to reliably detect foreground app changes on Android. The Accessibility Service is used solely for this purpose. It does not read screen content, capture keystrokes, record audio, control other apps, or transmit any data. You can disable the service at any time in Android Settings.
