You already spend hours on your phone. What if that time was earned by learning something that actually matters? Shale locks your most distracting apps and only unlocks them after you study. Every flashcard you complete earns you one minute of screen time. When your time runs out, the apps lock again. No willpower needed. Just a simple deal: learn first, scroll later. HOW IT WORKS 1. Pick the apps you want blocked (TikTok, Instagram, YouTube, and more) 2. Tell Shale what you want to learn. Our AI creates a personalized flashcard deck in seconds 3. Study your cards and earn screen time. 1 card = 1 minute 4. Your apps unlock. When time's up, learn a few more cards to keep going AI-POWERED FLASHCARDS Just describe what you want to learn in plain English: "Help me study for my biology exam" or "Teach me basic Japanese phrases." Shale's AI generates a complete deck tailored to your level. You can also create cards manually or expand any deck with more AI-generated content at any time. SCIENTIFICALLY PROVEN LEARNING Shale uses spaced repetition to show you the right cards at the right time. Cards you struggle with appear more often. Cards you already know fade into the background. You learn faster with less effort. REAL APP BLOCKING This isn't a gentle reminder you can dismiss. Shale uses Apple's Screen Time API to actually block your selected apps until you've earned enough screen time. It works in the background, even when the app is closed. SCHEDULED BLOCKING Set daily blocking hours so Shale only steps in when you want it to. Block apps from 8am to 10pm, or keep them locked around the clock. LEARN ANYTHING Exam prep, new languages, job interview questions, coding concepts, history facts, or any topic you can think of. If you can describe it, Shale can teach it.

Verdict
The clearest difference is update cadence: Shale at every 5 days against Luwi's every 10 days. On price, ads, in-app purchases and device support there is nothing between them.
