Turn a scrolling break into DSA coding interview practice. Guard distracting apps, answer a quick question, and build a habit across seven interview topics. Build your DSA coding interview practice into the moments you already reach for your phone. DSA Lock combines an app blocker with short coding interview lessons. Choose distracting apps and daily lock times. When a practice session is due, your selected apps stay blocked until you finish a card and its recall question. PRACTICE BEFORE YOU SCROLL Read a focused explanation, study the code or diagram, and answer a quick question. See why the answer works, then unlock your selected apps until the next scheduled session. SEVEN INTERVIEW TOPICS. Build understanding across data structures and algorithms, low level design LLD, databases and SQL, object oriented programming, operating systems, computer networks, system design and aptitude puzzles. Explore C++ and SQL examples, complexity analysis, patterns, and common mistakes. MAKE RECALL A HABIT Follow the curriculum, revisit material with spaced review, and track your progress and streaks. Keep your daily practice small enough to fit between the other things you do. CHOOSE WHAT GETS BLOCKED Use Apple's Screen Time picker to choose the apps you want to guard. Set your own lock times and adjust your practice intensity. Emergency unlock options give you a temporary break when you need one. BUILT FOR IPHONE DSA Lock uses Screen Time permission to shield your selected apps. Supported iOS versions open DSA Lock directly from the shield, earlier versions use a local notification or manual opening. After practice, automatic return is available for supported apps, with clear manual guidance when needed. YOUR PROGRESS STAYS ON YOUR DEVICE No account is required. Your learning progress and selected app list stay on your phone.
