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.
Warpinator, use it to transfer files wirelessly between my PC and android phone.
What would be the difference between Warpinator and Local Send, I wonder.
