Flash Dictionary turns the world around you into a vocabulary notebook — whether you're picking up a new language or pushing into advanced words and phrases in one you already speak. Point your camera at a menu, a book, or a street sign — Flash Dictionary reads the words on it, looks up what they mean, and tucks them into a notebook you can come back to. Voice and typing work too, for the moments you don't have a photo. WHAT YOU CAN DO • Capture from photos. Snap a picture of any text and the app extracts the words worth learning, in the language you're studying. • Speak it in. Voice dictation lets you save a word hands-free, in 30+ language locales. • Hear it spoken. Every saved word gets a native-quality voice playback, with adjustable speed for tricky pronunciations. • Lean on AI. Meanings, example sentences, and part-of-speech are filled in automatically, so you spend your time learning, not looking things up. • Organise by language. Keep one notebook for Spanish, another for French — switch tabs with a tap, search across either. HOW IT WORKS 1. Sign in with Apple or Google. 2. Pick your native language and the languages you're learning. 3. Add a word by photo, voice, or typing — it syncs to your account and is ready next time you open the app. BUILT FOR 30 LANGUAGES Spanish, French, German, Italian, Portuguese, Mandarin Chinese, Japanese, Korean, Arabic, Russian, Turkish, Hindi, Bengali, Urdu, Persian, Vietnamese, Indonesian, Thai, Polish, Dutch, Swedish, Norwegian, Danish, Finnish, Czech, Romanian, Greek, Hebrew, Ukrainian, and English. WHY IT'S DIFFERENT • Works whether you're starting from scratch or already fluent — capture your first hundred words, or your next thousand advanced ones. • Built for the way people actually pick up vocabulary: in the wild, from real things you see and hear. • No drills, no streaks, no shame. The notebook is yours; revisit when you want. • Sentence-case spelling preserved consistently so your list always looks clean. • Free. No ads. No in-app purchases. PRIVACY Words you save and notes you write belong to you. They are stored against your account so they travel with you across devices. We don't sell or share your data, and we don't use your email for marketing. Sign in with Apple is supported. A pocket-sized, AI-assisted way to keep every word you pick up — from anywhere.

Verdict
The clearest difference is in-app purchases: Flash Dictionary at none against Lexicon's 8. Flash Dictionary also leads on ads (none vs shown) and iOS requirement (15.1 vs 17.6). On price, update cadence and device support there is nothing between them.
