FoundKey vs Morse Code

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.

Learn Morse code the right way through practice. Morse Code gives you 7 different training modes so you can learn at your own pace and in the style that works for you. From guided lessons to audio drills to real-time decoding — every mode is designed to build genuine fluency. INTELLIGENT LEARNING SYSTEM Our app uses spaced repetition algorithms combined with letter frequency analysis to optimize your learning journey. You'll master the most common letters first, building a solid foundation before progressing to less frequent characters. The system intelligently reviews letters at the perfect intervals to cement them in your long-term memory. MULTIPLE LEARNING MODES **Visual Learning** Watch Morse code patterns displayed on screen, helping you recognize the rhythm and structure of each letter and number. **Audio Learning** Train your ear with authentic Morse code sounds. Adjust the frequency and speed to match your skill level, gradually increasing the pace as you improve. **Practice Mode** Put your knowledge to the test with interactive practice sessions that reinforce what you've learned. **Callsign Practice** Prepare for real-world amateur radio operation with dedicated callsign recognition and practice. POWERFUL TRANSLATION TOOLS **Bidirectional Translator** - Convert text to Morse code instantly - Decode Morse code back into readable text - Multiple output options: sound, visual flash, or vibration - Perfect for communication or learning verification HIGHLY CUSTOMIZABLE Tailor the app to your exact needs: - **Adjustable Speed**: Start slow and gradually increase WPM (words per minute) as you improve - **Frequency Control**: Customize the audio tone to your preference FREE FEATURES - Complete visual learning mode - Full translation capabilities (text ↔ Morse) - All output methods in translation (sound, flash, vibration) - Customizable speed and frequency settings PREMIUM UPGRADE Unlock the complete learning experience: - **Callsign Practice** for amateur radio preparation - **Audio Learning Mode** for comprehensive ear training - **Ad-Free Experience** for distraction-free learning - **Lifetime Access** - pay once, learn forever
