About
x-doo is the name under which I, Nenad Karalić, an independent developer from Serbia, publish my software. There's no company or investors behind it: every app is designed, built and supported by me.
What that means for you: software that does one thing well, works without the internet, keeps your files on your computer, and has a fair one-time price instead of a subscription. When you write to support, you talk to the person who wrote the code.
