Update: I tried with my iPad and connection is good with it so the connection issue might be with my phones (they're relatively old now).
But app opens up very differently on iPad, its elements are placed in a strange way that some parts of the app are unusable and some parts can't even be opened.
I think this can be fixed easily and fast. And if I remember correctly other people also mentioned on this forum that they want to use it with iPad. If done correctly using the app on iPad will be so much fun. If you can just make it identical to iPhone version, that would be good for now.
You can test CsTimer on iPad, you can test it with WebBLE browser.
But warning, no guarantee that it will work. Some iOS users use it for the Giiker cube
Android users can use regular Chrome. Choose in the options the Giiker.
I have the same problems, Gan knows the problems since months. If you ask for help or updates you get a copy and past answer.
Oh my funny solution: I'm using a mirror App on Android and stream it to the iPad for a big screen size
