Khat vs FoundKey

Khat is the easy, fun way to improve your Arabic handwriting and master the basics of Arabic calligraphy. It teaches both Ruq'ah (خط الرقعة) and Naskh (خط النسخ) letter by letter with guided on-screen strokes, then trains you on letters, words, sentences, numbers and letter connections at your own pace, on iPhone or iPad, with your finger or Apple Pencil. WHY KHAT • Practical handwriting improvement: trace each letter's path with instant feedback whenever your stroke drifts off • Two core scripts: fast, everyday Ruq'ah and the clear, readable Naskh used in books and the Quran • A logical progression: single letters, then words and sentences, then ligature "ladders" and numbers • Your own sentence: type any text and practice it in the script you choose • Daily challenges that refresh every day, plus tournaments against real learners • Badges, streaks, points and a weekly leaderboard to keep you motivated • School homework: teachers can assign challenges to their students, shown with a School Challenge badge • An ink and paper shop to personalise your writing board • Fully bilingual: Arabic and English WHO IS IT FOR • Anyone who wants better Arabic handwriting: students, teachers, professionals and parents • Arabic learners who want to form the letters correctly from the start • Calligraphy hobbyists who want solid foundations before pens and ink NEW IN THIS VERSION • Better support for large screens, iPhone Duo and iPad multitasking • Prices shown in your local currency • Performance and stability improvements Download Khat today and start writing beautifully.

FoundKey is a hands-on cryptography toolkit and learning app. Run real cryptographic operations, see exactly how ciphers transform your text, build multi-step cipher recipes, and trade encrypted messages and code-cracking challenges with friends - all in a beautiful, fast, fully offline app. WORKBENCH - 45+ OPERATIONS • Encode & decode: Base64, Hex, Binary, URL, Morse code (with audio playback), and more • Classical ciphers: Caesar, Vigenère, Atbash, Rail Fence, Playfair, Enigma, and friends • Modern crypto: AES, ChaCha20, Blowfish, and other symmetric ciphers • Hashing & key derivation: SHA-256 and the SHA-2 family, MD5, BCrypt, Argon2 • Utilities: frequency analysis, text tools, random keys, and more SEE HOW CIPHERS ACTUALLY WORK Tap "Explain" and watch your own text get transformed step by step - letter shifts, key alignment, rail patterns. It's the fastest way to truly understand a cipher: not a diagram from a textbook, but your message, traced live. CIPHER LAB - BUILD YOUR OWN ENCRYPTION Chain operations into reusable recipes: Vigenère into Base64 into reversed text — whatever you can dream up. Save, color-tag, and share recipes, or publish them as "black box" puzzles where friends must figure out the password. LEARN - A CRYPTOGRAPHY LIBRARY IN YOUR POCKET Illustrated chapters take you from ancient ciphers to modern encryption and hashing, with progress tracking as you read, test, and master each topic. MESSAGES - REAL ENCRYPTED NOTES Compose messages encrypted with real algorithms and pass them to friends by QR code, AirDrop, or link. They decrypt in the recipient's app with the key you share. No accounts, no servers — the message travels inside the code itself. CHALLENGES - CRACK THE CODE Solve built-in puzzles across difficulty tiers, race the clock, use hints sparingly - or craft your own challenges and dare your friends. PRIVATE BY DESIGN • No account, no ads, no analytics, no tracking • Everything stays on your device; works fully offline • Sensitive clipboard copies expire automatically and never sync to other devices • History auto-deletes on your schedule POWER-USER FRIENDLY • Siri Shortcuts for Base64, Hex, and SHA-256 • Spotlight search for operations, articles, and recipes • Deep links and .cwb files for sharing • Beautiful native design for iPhone and iPad, light and dark FREE VS PREMIUM Free forever: all 45+ operations, 5 cipher recipes, the first Learn chapters, starter challenge packs, and unlimited message exchange. One single purchase — no subscription — unlocks unlimited recipes, all 8 Learn chapters, every challenge pack, and early access to new features. Whether you're a puzzle lover, a student, a developer who needs a quick Base64 or hash, or just someone who thinks Enigma machines are cool — Crypto Workbench turns cryptography from a black box into a playground.
