Make your own flashcards in seconds and let spaced repetition tell you exactly what to review today. CardFlip is a free flashcard maker for students who want to memorize words, terms and formulas without an account, without a paywall and without an internet connection. FOUR WAYS TO STUDY YOUR CARDS - Flip: classic flashcards with a smooth 3D turn. Tap to reveal the answer, then rate how confident you were from 1 to 5. - Quiz: multiple-choice questions built automatically from your own study cards. - Match: find the front-and-back pairs in a memory grid and beat your own time. - Type: write the answer from memory to test real recall, not recognition. SPACED REPETITION THAT DOES THE PLANNING Spaced repetition is the reason flashcards work. CardFlip schedules every card for the day you are about to forget it, so a few minutes of revision each morning replaces a night of cramming. Each deck shows how many cards are due today, so you always know where to start. BUILT FOR REAL STUDYING - Unlimited decks and unlimited study cards. - An optional hint on any card for when you are close but not quite there. - Tag decks by subject - Spanish, biology, anatomy, history, GRE, SAT. - Search every card in every deck at once. - Import hundreds of cards from a CSV or a tab-separated file, export any deck as JSON. LEARN VOCABULARY OFFLINE Every deck lives on your device. Language learning cards work on a plane, on the metro and in a basement lecture hall. Nothing to sync, nothing to log in to. TRACK THE WORK - A daily streak, and a record of your best one. - XP for every card studied and every quiz answered. - Achievements as your decks fill up. - A weekly chart of the minutes you actually put in. - A progress ring on every deck showing how much of it you have mastered. PRIVACY FIRST Your decks and your progress stay on your device. No account. No personal data collected. Your study cards are yours alone. MADE FOR STUDENTS Light and dark themes, smooth flip animations, tuned haptics and adjustable card text - the small things that make revision cards something you actually open. Whether you are learning a language, prepping for the GRE or SAT, memorizing medical terms, revising for school exams or building vocabulary, CardFlip is your offline study companion. Download CardFlip and start memorizing, one card at a time.

FlashDB is a simple, focused flashcard study app. It does one thing well: lets you study cards you create or import, without ads, accounts, trackers, or cloud services. STUDY YOUR WAY • Quiz mode shows four answer choices for every question. • Flashcard mode flips cards to reveal the answer. • Pick the number of questions per session — 5, 10, 20, 50, All, or any custom count. • Shuffle questions so you don't memorize the order. BUILD YOUR DECK • Add questions one at a time from inside the app. • Import question sets from a JSON file in your Files app. • Attach images to questions for visual prompts. • Export the whole database to back it up or share it. ORGANIZE WITH TAGS • Tag any question with one or more labels. • Use the Filter by Tag button on the home screen to scope a session to just the tags you pick. • Tags travel with exported JSON. TRACK YOUR PROGRESS (OPTIONAL) • Show Live Score and an answer-confirmation haptic during quizzes. • Track Question Performance counts attempts and misses, then surfaces a Study Weak Only mode for the questions you keep getting wrong. • Show Study History gives you a daily streak and a 7-day session count on the home screen. • Every progress feature is off by default. Turn on only what you want. DESIGNED FOR EVERYONE • Full VoiceOver support, including custom rotor actions for flipping and moving between cards. • Honors Reduce Motion, Dynamic Type, and your color scheme. • iPad keyboard shortcuts: Space to flip, ← and → to navigate cards, ⌘N to add, ⌘S to save. • Optional "blind quiz" mode hides per-answer feedback so you only see your total when the session ends. PRIVACY YOU CAN VERIFY • No accounts, no sign-up, no tracking. • No third-party analytics or ad SDKs. • No internet access required after install. • All questions, images, and session history stay on your device. A small starter set of 25 sample Spanish-English questions is bundled with the app so you can start studying the moment you open it. Add your own, import sets you've found, or delete the starter cards and never look back — it's your library. FlashDB is intentionally simple. Every visible new feature is gated behind a setting that defaults to off, so the app stays focused unless you decide otherwise.

Verdict
The clearest difference is in-app purchases: FlashDB at none against CardFlip's 1. CardFlip's advantage is iOS requirement (15.0 vs 17.6). On price, ads and device support there is nothing between them.
