Sidetone CW vs Morsenger

Sidetone is the ultimate app for anyone looking to learn Morse code (CW) from scratch or sharpen their existing telegraphy skills. Whether you're a curious beginner or a ham radio operator wanting to increase your speed, Sidetone offers the tools you need in a clean, modern, and ad-free interface. KEY FEATURES: • Learn with the Koch Method: Build your speed the right way. Sidetone uses the highly effective Koch method, which trains your ears to recognize characters at full speed from day one, preventing the bad habit of counting slow dots and dashes. • AI-Powered QSO Simulator: Train for the real world! Our smart simulator uses an external API to generate realistic radio contacts (QSOs). Practice sending and receiving exchanges just like on the actual bands, giving you the confidence you need before sitting down at the rig. • Intuitive Input: Send your Morse code using the app's responsive, circular key and get immediate visual and audio feedback on your timing. • No Login Required: Sidetone respects your privacy. Open the app and start practicing right away—no accounts or passwords needed. Sidetone is a passion project created for the love of amateur radio and coding. The app is completely free to use, but if you enjoy it and want to help support the server costs (and fuel the developer's coffee intake), there's a voluntary tip jar in the settings. Fire up Sidetone, put on your headphones, and start your CW journey today. 73!

Morsenger is a complete Morse code toolkit for learning, encoding, and decoding — built for students, history enthusiasts, amateur radio operators, and anyone curious about the language that changed the world. DECODE Listen through your device's microphone to decode Morse code signals in real time. A scrolling waveform timeline shows signal activity as characters are recognized. Import audio and video files (WAV, MP3, M4A, FLAC, AIFF, and common video formats) to decode recorded transmissions. The decoder auto-detects frequency and words-per-minute, adapting to noisy or imperfect signals. Gap-based decoding also recognizes percussive tapping — tap on a desk, table, or any surface and watch your message appear. ENCODE Type any message and hear it rendered as authentic 1970s-style Morse audio. Export recordings in Apple Lossless format or share directly via iMessage. Stealth mode shifts the tone to near-ultrasonic frequencies for transmissions that are virtually inaudible to most listeners. TELEGRAPH KEY An interactive key turns your device into a working telegraph station. Use mouse clicks, touch, or keyboard input to send Morse with real-time audio feedback. Your transmitted characters are decoded and displayed as you key them. GAME Learn Morse code through a hangman-style game with word and phrase modes across multiple difficulty levels. The game draws from a curated library of over 1,500 WWII military messages, making practice both educational and historically grounded. PRACTICE A dedicated practice mode lets you study letter by letter. Tap the play button to hear the correct dit-dah pattern for any character, then build speed and confidence at your own pace.
