Features
Read full description

Security Guard License Prep is the focused study app for unarmed guard licensing in California (Guard Card / BSIS), New York (security guard registration / NYS Dept. of State), Florida (Class D Security Officer License / FDACS), and Texas (Level II Non-Commissioned Security Officer / Texas DPS). Pick your state and study exactly what your training and license actually cover โ€” with 2,363 original questions and full-length timed mock exams. A purchase is required to use this app. There is no free version. EVERY CORE TOPIC, DRILLED โ€ข Legal Powers & Limits โ€” what a guard's arrest, detention, search, and trespass authority actually is, and where it stops. โ€ข Use of Force โ€” the force continuum, the reasonable-force standard, restraints, and weapons authorization. โ€ข Observation & Reporting โ€” incident report writing, note-taking, evidence preservation, and chain of custody. โ€ข Emergency Response โ€” fire, medical emergencies, bomb threats, evacuations, and active-threat scenarios. โ€ข Public Relations โ€” de-escalation, customer service, and working with police and the public. โ€ข Ethics & Conduct โ€” integrity, confidentiality, and the judgment calls that define a professional guard. โ€ข Patrol Procedures โ€” patrol technique, access control, key control, alarm response, and post orders. STATE SELECTOR, BUILT IN Switch between California, New York, Florida, and Texas any time. Each state gets its own onboarding, timed mocks, and readiness score โ€” progress in every state saves separately. FULL-LENGTH TIMED MOCK EXAMS Run a mock built to match your state's real training emphasis. Answers lock once submitted, just like test day. A RATIONALE FOR EVERY SINGLE QUESTION Not just "the answer is B." Every question explains the reasoning behind the correct answer and the most tempting wrong one. KNOW WHEN YOU ARE READY โ€ข Readiness score that moves as you study, per state โ€ข Per-section mastery and weakest-subtopic breakdown โ€ข Score trend across every mock you take โ€ข Countdown to your test date, daily question goal, and streak STUDY THE WAY THAT STICKS โ€ข Quick practice: 10, 25, or 50 mixed questions โ€ข Practice by topic and by subtopic โ€ข Weak-area drills built automatically from the questions you actually missed โ€ข Flashcards with spaced repetition โ€” miss a card and it comes back sooner โ€ข Review every question you got wrong, plus everything you bookmarked BUILT THE WAY IT SHOULD BE โ€ข Works fully offline. The entire question bank ships inside the app. โ€ข No account, no sign-up, no email. โ€ข No ads, no analytics, no third-party SDKs. Nothing leaves your device. โ€ข Full VoiceOver support and Dynamic Type. Light and dark mode. iPhone and iPad. SUBSCRIPTION & PRICING โ€ข Monthly Access โ€” $9.99 per month, billed every 1 month. โ€ข Annual Access โ€” 3-day free trial, then $49.99 per year (about $4.17 per month), billed every 12 months. โ€ข Lifetime Access โ€” $99.99, a one-time purchase.
