Frequently asked questions
Learn what the Android app supports, where progress is stored, and how the open-source project can be inspected or improved.
How do I enter dots and dashes?
You can use separate dot and dash controls, one-button press-duration input, or optional volume-button input. In one-button mode, a short press enters a dot and a longer press enters a dash.
Do I need an account?
No. Training history and learned status are stored locally on your Android device, so the app does not require an account for practice.
How does the app help me remember Morse?
Exercises combine spoken characters, Morse sound feedback, immediate correction, replay after mistakes, and mnemonic phrases. Progress information helps the app keep practice focused on a small character set.
What is the online Morse key?
The online key is a browser-based demonstration of one-button Morse input. The Android app adds guided exercises, audio, mnemonic support, and locally stored progress.
