Sphinx - Math App Blocker

Add healthy friction to break out of your addictive screen time habits - decide whether it's worth it to face the sphinx.

Is 5 more minutes of scrolling worth solving a math problem?

Sphinx makes you answer that question — not with a hard limit, not with a button you tap through, but with a real challenge that forces your brain to engage. When that challenge interrupts you, you make a conscious decision instead of continuing on autopilot.

HOW IT WORKS Choose which apps you want Sphinx to guard — social media, news, games, whatever pulls you into mindless scrolling. Set how often Sphinx interrupts — customize it to your needs. When your interval hits, Sphinx drops an OS-level shield over your apps mid-use. To continue, solve a challenge. Or walk away and reclaim your time. Either way, it was your decision.

REAL CHALLENGES, NOT FAKE BARRIERS Multiple choice math, typed answers, number sequences, and memory grids. Three difficulty levels — from a gentle pause to serious effort. Sphinx gives you friction, not restriction. You're never locked out. You always have the choice to continue.

BUILT AT THE SYSTEM LEVEL Sphinx uses Apple's FamilyControls framework to shield apps at the operating system level. This isn't an overlay you can swipe away or a notification you can dismiss. When Sphinx activates, the shield is real.

YOUR DATA STAYS ON YOUR DEVICE No sign-up. No email. No phone number. Install it and go. Everything is stored locally. No analytics, no telemetry, no third-party SDKs. Sphinx doesn't know which apps you use or how long you use them — it only receives callbacks from Apple's system frameworks. Sphinx was built on a simple idea: most screen time apps either block you completely or give you a button to ignore. Sphinx does something different — it makes you decide.
