Turn your screen time into study time. Delay makes you answer practice questions on topics you want to learn before you can open distracting apps like Instagram, TikTok, or YouTube. Instead of setting aside more time to study, learning becomes a transparent layer integrated into something you already do every day. EARN YOUR SCREEN TIME Before opening a blocked app, Delay gives you a few quick practice questions. Answer them correctly to earn access. Every time you reach for a distracting app, you get another small repetition of something you actually want to learn. LEARN WHAT YOU WANT Choose exactly what you want to study. Whether you're learning a language, preparing for an exam, memorizing important concepts, or building knowledge in a new subject, Delay turns your material into questions you can practice throughout the day. LEARN THROUGH REPETITION Delay integrates learning into moments that would otherwise be spent scrolling. Instead of relying on long study sessions, you repeatedly encounter your material throughout the day. Over time, those small repetitions add up. END THE DOOMSCROLL Your apps automatically lock again after your earned screen time expires. If you want to keep scrolling, you study again. This creates a simple cycle: learn, unlock, scroll, repeat. IMPORT YOUR STUDY MATERIAL Bring the material you already want to learn into Delay and turn it into practice questions. Keep different subjects organized and choose what you want to practice when unlocking your apps. TRACK YOUR PROGRESS See how much you've practiced, how consistently you're answering questions, and how your knowledge improves over time. The screen time you would have spent scrolling becomes measurable learning progress. SEAMLESS INTEGRATION Delay works directly with your apps so studying becomes part of your normal routine. Once it's set up, simply use your phone as usual. When you try to open a blocked app, Delay gives you your questions, you answer them, and you're right back in. MAKE SCREEN TIME USEFUL You’re already going to open your favorite apps throughout the day. Delay simply puts learning in between. Instead of finding more time to study, use the time and habits you already have. DOWNLOAD DELAY Delay requires a subscription to access certain features. Download Delay and start turning everyday screen time into learning time. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
