@jerzecokno Use clickable to create an app skeleton by choosing the Python template.
Then copy the content of the Main.qml file of the project I pointed you to. Create a public repository somewhere and then if you have any concrete questions on how to proceed, either ask them here or join our App Development Telegram channel for more interactive support.

Yeah, this needs definitely some improvement. App development (not only for webapps) is held back by not recieving enough attention for too long making it way to difficult to deliver great applications at the moment. My respect to everyone who is developing anyways, there are some great apps on Ubuntu Touch!

If you have wishes or ideas how to improve the problems, be sure to speak up.
