RapidZapper for now Essential store all the data on your phone only so that might be a part of the challenge to bring it to the web/PC
You can limit it to work between Nothing phone(s) and PCs when they are on the same network. I would argue that having access to it when you are not anywhere near your phone is not really important in that case. But at home/work, on same WiFi, it would be a killer feature and it’s still technically on-device, it’s just being “streamed” to web version. Just like Quick Share for example works.
