Cogio: Daily Brain Workout

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 presents a quick problem: math, logic, sequences, or focus challenges. Solve it, and the app opens. It takes about 10 seconds, and those seconds add up to a sharper, more focused mind and less mindless screen time.

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 consciously whether to keep going, and your brain gets a rep either way. It's brain training built into the phone habits you already have.

Most people solve 5–20 problems a day without even trying, just by going about their normal phone use. No extra time required.

What kind of problems?

- Mental arithmetic — fast calculation to keep your number sense sharp.
- Logic problems — deductive reasoning, set membership, and odd-one-out.
- Number sequences — pattern recognition and working memory.
- Pattern recognition — Raven's-style matrix reasoning.
- Inhibition challenges — Stroop-style tests for focus and impulse control.
- Visual memory — recall and compare what you just saw.

Each problem is generated from a bank of over 150,000 stems across six categories, so your brain never autopilots through the same problem twice. Like brain games, but built into your day.

How it works

1. Choose which apps to guard — social media, video, news, or any app you open too often.
2. Open a guarded app as you normally would.
3. Cogio presents 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 reduce screen time without deleting their apps, and anyone who wants to stay mentally sharp without carving out extra time. If you already pick up your phone dozens of times a day, you already have everything you need for a daily cognitive workout.

Built for privacy

No account required — Cogio works without ever asking who you are. We use a standard analytics tool to understand broad usage patterns like how many people open the app; it's never used for ads or to track you across other apps, and your guarded apps, problem history, and scores stay on your device. Purchase and subscription status are processed securely through Google Play and our payment provider to keep your Pro access working across sessions.

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.
