Pass your CompTIA exams — one flashcard at a time.
A flashcard app built for CompTIA certification prep. Five decks — A+, Network+, Security+, CySA+, and Linux+ — with 750+ cards, spaced repetition, and scenario-based questions that mirror the real exams. The A+ deck is completely free. Fully offline once downloaded.
Most CompTIA study apps just throw cards at you in the same order every time. CertFlash uses spaced repetition — the SM-2 algorithm — so the cards you find hard come back sooner and the ones you've mastered come back later. You spend your time where it counts.
The cards go beyond definitions. Scenario-based and performance-style questions mirror the way the real exams test you, so you're not just memorizing terms — you're practicing how to apply them under exam conditions.
Built natively with SwiftUI. Works fully offline once downloaded, syncs your favorites across devices with iCloud, and supports dark mode out of the box.
Every deck includes scenario-based and performance-style questions modeled on the real exams.
The SM-2 algorithm schedules every card based on how well you know it. Rate each card Again, Hard, Good, or Easy and CertFlash decides when you'll see it next — so weak cards resurface and strong ones space out.
Test yourself with a random set of 10, 20, or 50 questions, separate from your spaced-repetition schedule. Perfect for a fast knowledge check before exam day without affecting your review queue.
See your progress per deck and a Due for Review count that tells you exactly what's ready to study today. Always know where you stand and what to tackle next.
Build a daily study habit with streak tracking and milestone celebrations. Daily reminder notifications keep you coming back, and a burst of confetti marks every completed session.
Bookmark tricky cards and search across all 750+ at once. Your favorites sync across devices via iCloud, so the cards you flag on your iPhone are waiting on your iPad.
Built natively with SwiftUI. Swipe to move through cards, study fully offline after download, and switch to dark mode for late-night review sessions.
CertFlash is great for drilling. When you want the full explanation behind a concept, IT Study Hub has free CompTIA study guides, roadmaps, lab walkthroughs, and resources covering certifications, networking, security, and core IT.
Flip a card, then read the guide — the two are built to work together.
