Turn your Spanish into a secret language of emoji and symbols… and back again. Write messages only your friends can read, learn it through play, and share one-of-a-kind cards. Every letter, number and sign has its own symbol from a fixed table, so anything you write can always be read back. Type a normal message and watch it appear in Marlek; paste a message in Marlek and reveal it in Spanish. WHAT YOU CAN DO • Two-way translator: Spanish to Marlek and Marlek to Spanish. • Learn Marlek: rank up, keep your streak, and master the cipher through four games — no key sheet needed. • Shareable cards: turn a message or your rank into a beautiful card for your stories and chats. • My Messages: save your favorite translations on your device to revisit anytime. • Table: the full key sheet with every symbol. Print it to decode on paper too. • Marlek Keyboard: a system keyboard to write Marlek messages inside other apps. • Siri & Shortcuts: translate with your voice or from a shortcut. MADE FOR THE WHOLE FAMILY Marlek is perfect for sending secret messages between friends and siblings, playing decode-the-clue, or just having fun with an invented language.
