Build your vocabulary in historical languages by reading iconic texts in Latin, Greek, French, Arabic, and German. Instead of practicing language with boring stock sentences, read the real texts that shaped civilization. For centuries, scholars learned languages by studying significant texts, not canned exercises. In CodexTutor, we are inspired by that approach. HOW IT WORKS A passage arrives as a stack of cards, one chunk of the original on each. Read it. Tap to check the translation. Swipe right if you had it, left if you didn't. Tap any word for its dictionary entry: headword, part of speech, what it means. No hovering crib telling you what the sentence says. The lexicon is at your elbow and the meaning is yours to assemble. At the end, you will be able to read the whole passage. Then, you will move on to the next passage! VOCABULARY THAT KNOWS YOUR TEXT Every text carries its own vocabulary, ordered by how often each word appears in that text — not a generic frequency list. When previewing vocabulary, high frequency words are prioritized. The system is meant to making reading the real text easier. THE LIBRARY Readers can choose from iconic texts in Latin, Greek, Arabic, French, and German. Modern languages and some ancient texts have audio. Homer and Virgil. More texts are always being added. WORKS OFFLINE. NO ACCOUNT. Texts download once and stay on your phone. There is no sign-in, nothing to subscribe to, and nothing about your reading leaves your device.

Morse Trail

Morse Trail turns learning Morse code into something you can see, hear, and feel. Most apps make you memorize a chart. Morse Trail builds the code into muscle memory by engaging four senses at once: you trace the path of each letter along an interactive Morse tree with your finger, while you hear the tone and feel every dot and dash through haptics. Sight, sound, touch, and motion reinforce each other — so the code sticks. LEARN BY TRACING The classic Morse tree, redesigned to fit on a single screen. Dots go left, dashes go right. Follow the path with your finger and your hand learns the rhythm. SIX WAYS TO PRACTICE • Learn — trace new letters on the tree • Listen — decode what you hear • Key — tap out symbols yourself • Words — build real words from the letters you know, or switch to the ham set: Q-codes, CW abbreviations, RST reports and callsigns • Challenge — beat the clock • Review — smart spaced repetition brings back what you're about to forget BUILT TO MAKE IT STICK • A guided 15-unit course from E and T to the full alphabet and numbers • Reviews are timed by how well you remember each symbol, not by how much you practice • XP, levels, and daily streaks keep you coming back • Optional reminders, including an evening nudge when your streak is at risk • A Home Screen and Lock Screen widget with your streak, level, and mastered symbols • Adjustable speed with Farnsworth timing — fast characters, comfortable gaps • Real sidetone generated on device, plus precise Core Haptics ON YOUR APPLE WATCH The watch app comes with Morse Trail for iPhone and keeps working when your phone is out of reach. Feel every dot and dash on your wrist, with haptics that make a dot (a quick tap) easy to tell from a dash (a long buzz). Switch on Sound to hear the code too, practice with the Feel & Guess quiz, mirror playback from your iPhone in real time, and keep your streak on a watch-face complication. YOURS, PRIVATELY • Works 100% offline — learn on a plane, on the trail, anywhere • No accounts. No ads. No analytics. No tracking. • Data Not Collected — everything stays on your device DESIGNED FOR iPHONE & iPAD Beautiful themes, full Dynamic Type and VoiceOver support, and a clean interface available in 12 languages. On iPad, a sidebar keeps every section one tap away, and in Key mode a hardware keyboard works as a telegraph key: tap Space for a dot, hold it for a dash. The first four units and the Learn and Listen modes are free, and Morse Trail Pro, a one-time purchase, unlocks the full 15-unit course, all six modes, and every theme. Whether you're a ham radio operator, a maker, a student, or just curious — Morse Trail is the most hands-on way to finally learn Morse code. Download and trace your first letter today.
