After installing, please go into the settings and enable SMS Morsify -- it is installed disabled by default.
You can set the duration of the dits and dahs in the settings, as well as change the gap durations to make transmission faster and slower, depending on your proficiency level.
You can set a delay before the start of the transmission, so that your normal Notification vibration does not interfere with the Morse code playback.
The transmission in Morse code can be stopped by turning the screen on.
Please note that for security, SMS Morsify does not have permissions to access the network.
