JS is optional, it’s unpleasant, as well as use a bunch of fat frameworks. But now there is HTMX, which makes any GUI without JS, pure HTML combined with some Bootstrap 5 is enough. I write in Go, it has a great built-in template, and it’s enough for any level of GUI

Open Signal rewiews on GooglePlay, there’s every third review about this situation. I forgot to mention, i’m talking about the Android version. The ios version works on ipad at the same time

Unfortunately the Signal recommended by many people may not work for you, it cannot work on multiple mobile devices at the same time, for example on a smartphone and tablet.

I don’t understand why no one recommends Jami? It’s the only messenger that works without a server at all. And yes, it has the ability to forward messages to itself (to use as a note) and works on any devices at the same time.

Depends on the task
