## What is Cerbio?

Most apps are designed to be opened without thinking. Cerbio turns those moments into a daily cognitive workout.

Every time you open a guarded app, Cerbio 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. Cerbio is the gym.

Most people solve 5–20 problems a day without even trying — just by going about their normal phone use. Cerbio fits cognitive training into moments that already exist in your day, no extra time required.

Who is Cerbio 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. Cerbio 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

Cerbio Pro
Cerbio is free to download. Cerbio 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
Cerbio'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.

Cerbio 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.

## Version history (last 5 releases)

### 3.0 — 2026-10-23

This release is a full redesign. Meet the new mascot — Cerbi — a hand-drawn, animated brain who waves you in, cheers your solves, and flexes when you rank up. The app icon, wordmark, and every screen have been rebuilt around a single visual language, with a dark-first theme and a light option in Settings.

New problem types join the gym: Odd One Out, Ordered Tap, Matching Pair, and Missing Number, plus new pattern problems — rule matrices, visual sequences, and mental rotation — under the Patterns category. Every problem is still randomized, so there's nothing to memorize.

The gate feels better to use. Correct answers fill green with a check and a tap of haptic feedback; wrong ones shake the card and let you try again. Rank-ups now get a proper celebration, and you can share your Cognitive Profile as a card straight from the Profile screen.

Also in this release: a clearer Pro page that leads with guarding multiple apps, smoother launch and welcome screens, and dozens of small fixes. As always, which apps you guard, your scores, and your settings never leave your phone.

Your brain is a muscle. Cerbio is the gym.
