ChessUnlock vs Sphinx

ChessUnlock helps you reduce screen time, improve focus, and build a better chess habit by turning distracting apps into chess puzzles. Choose the apps that pull your attention, such as Instagram, YouTube, Reddit, Discord, or other distracting apps. When you want to unlock them, ChessUnlock gives you a chess puzzle first. Solve the puzzle, choose your break time, and continue with more control. ChessUnlock is designed for people who want to stop automatic scrolling, reduce social media distractions, improve discipline, and practice chess in a simple way. Features: • Lock distracting apps • Unlock apps by solving chess puzzles • Choose your unlock/break time • Practice chess tactics while reducing distractions • Build focus and self-control • Simple setup and clean design • Useful for studying, working, and avoiding mindless scrolling ChessUnlock is not just another app blocker. Instead of only stopping you, it gives you a small chess challenge before your break. This helps you pause, think, and make a more intentional choice. Use ChessUnlock to stay focused, reduce screen time, and improve your chess one puzzle at a time.

Most app blockers ask you to have willpower. Sphinx asks you to have two minutes and a working brain. Lock the apps that eat your evening. When you want back in, you don't tap "ignore" — you solve a chess puzzle. HOW IT WORKS 1. Pick the apps you want locked, and choose how long the lock lasts. 2. Open one of them and you hit the Sphinx shield instead. 3. Solve a puzzle to buy back five minutes. Solve more for longer. EACH UNLOCK COSTS MORE THAN THE LAST The first unlock in a lock window costs one puzzle. The second costs two. The third costs three. After that, you wait until the window ends. The price is on screen before you commit, so a long session never feels free. PUZZLES, NOT TIMERS • 2,499 mate-in-one chess puzzles, every one verified solvable • Number pattern puzzles if chess isn't your thing • Everything is solved on device, so no connection is needed NO ESCAPE HATCH There is no "just this once" button, no snooze, no early exit. A lock window runs until it ends. Apps inside one can't even be removed from your list until it does. PRIVATE BY DESIGN Sphinx never learns which apps you locked. Your selection is handled entirely by Apple's Screen Time framework and stays on your device. No account, no sign-up, no tracking. LIGHT AND DARK Pick either, or follow your phone. — Sphinx uses Apple's Screen Time permission to lock and unlock the apps you choose. It cannot see your activity in those apps, and it cannot see which apps you selected. Sphinx Pro is an auto-renewable subscription: $4.99 per month or $29.99 per year.
