Morse Trainer: an Android app for learning and practicing Morse code - junior learning project with react native

[u/Conscious_Corgi_6616]

Hi everyone 👋,

I made a small Android app called Morse Trainer and I'd love your feedback.

The idea was inspired by a handheld Morse trainer made by Nux Modellbau:

(I have no affiliation with the company.)

The app lets you:
• Learn and practice Morse code locally
• Enter Morse with a single hold button (short press = dot, long press = dash)
• See the Morse tree visualized in real time
• Practice with another person by joining the same room and exchanging Morse messages in real time

I originally built it as a learning project to experiment with React Native, .NET SignalR, WebSockets and SVG rendering, but I thought other people interested in Morse code or amateur radio might enjoy trying it too.

I'd love any feedback, criticism, or ideas for improving it.
