Every inch of the screen is your straight key. Press anywhere to send — it lights up and plays a sidetone. RECEIVE — the Koch method with Farnsworth timing. Start with two characters at real-world speed (15-25 WPM) and unlock the next at 90% accuracy, through 40 levels. The answer pad shows only the characters you have learned, so there is nothing to second-guess. SEND — real-time decoding with automatic dit/dah calibration. Watch yourself descend the Morse code tree with every keypress: hold for left, tap for right, with dot and dash waypoints always showing where the next press leads. Targets grow from single letters to common CW abbreviations and callsigns. CHART — the full alphabet, numbers and punctuation. Tap any row to hear it at your configured speed and tone. SETTINGS — character speed 15-25 WPM, effective (Farnsworth) speed 5-15 WPM, sidetone 400-1000 Hz, key haptics. Volume follows the silent switch. PRICING — all training features are free, with no ads. A one-time Pro (Supporter Pack) purchase adds alternate app icons, theme colors and a 30-day progress chart. Everything stays on your device — no account, no tracking, fully offline.
