Locked In: Prep for Security+

Locked-In is a bite-sized study companion for the Security+ (SY0-701) exam. Built for people who study in 10-minute windows on the train, on lunch, or between meetings — every lesson is short, focused, and ends with a quick-check so you know what stuck.

WHAT'S INSIDE
• All 5 SY0-701 exam domains, broken into bite-sized lessons
• Visual diagrams for every key concept (CIA triad, PKI, AAA, IR phases, and more)
• Inline quick-checks at the end of each lesson
• A 500+ question practice bank, organized by domain and difficulty
• Performance-based questions (PBQs) — drag-and-drop, matching, and ordering
• A full 90-question, 90-minute timed mock exam with flag-for-review and a final review screen
• Flashcard deck of must-know terms with spaced repetition
• Searchable glossary covering every acronym you'll see on test day
• Progress tracking, streaks, bookmarks, and personal notes
• Weak-spot review that surfaces the topics you keep missing

WHO IT'S FOR
• Career changers studying Security+ alongside a day job
• Students supplementing a course or boot camp
• Professionals refreshing before a recertification window
• Anyone who learns better in short, focused sessions than long lectures

WHY LOCKED-IN
• Works fully offline — no account, no tracking, no ads
• One-time unlock, no subscription
• Built by an indie developer, not a content mill
