I still use it on for my Samsung watch, but i just dont give it network permission. The advantage of being on graphene os.

Fedora writer also works fine for basic flashing

I use autodesk inventor, which is like the more professional version of fusion360. But there is no free version and it is very expensive, i have a free student licence.

I like it way more than fusion360, and it is much better at Assembly’s. Still clumsy sometimes.

It doesn’t run on linux so i just remote into an old windows laptop when i need it.

I have tried freecad and onshape a lillte but i am just so used to inventor that its harder to use them.
