Lockin allows you to score Straight A's while minimizing study time
Built for What Students Actually Need
Rote memorization wastes your time and actively holds you back
Optimize your focus and studying in three easy steps.
Lockin helps you bridge the gap between procrastination and flow state with a custom physical and mental checklist.
Lockin synchronizes instantly across all tabs. Close the tab, open it elsewhere — your timer remains synchronized.
Lockin integrates active recall directly into your dashboard. Build question databases, track your progress, and improve through practice.
Just the fundamental tools you need for deep work.
Fully synchronized Pomodoro timer featuring dynamic break scheduling, subject tagging, and a practice problem database.
Create questions and practice sets directly in your dashboard. Test yourself with active recall checks to keep track of difficult concepts and problems.
Organize study sessions by topic or class. Track your time invested in each subject.
Monitor focused hours and tag distributions. Analyze logs and weekly patterns to verify if today was more productive than yesterday.
A zero-mouse interface. Use shortcuts to dynamically control timer states.
In his bestselling book How to Become a Straight-A Student, Cal Newport highlights a core cognitive reality: most students spend hours re-reading notes or highlighting textbooks, which creates a false "illusion of competence." They recognize the words, so they assume they know them.
Cognitive science indicates that true learning only happens through retrieval practice—the difficult, active process of forcing your brain to retrieve knowledge.
Lockin replaces passive cramming with active self-testing. By wrapping deep focus sessions with structured activation routines and integrated self-testing lists, we ensure you study less, but study deeper.
