Especially for those of us with no coding background, who can’t just build/edit an app.
For example, I like using Gadgetbridge to replace my fitness tracker app: https://gadgetbridge.org/
It’s not nearly as full-featured as a regular fitness app, but it literally can’t connect to the internet so there’s no way anyone can get my health info.
I had no idea about that.
I do remember how much I liked their various logos, be it those of Netscape and how madly I loved the old Mozilla t-rex logo — I still wear their old t-shirt from time to time, just because of that stupid but gorgeous head ;)
