About Solo Tuna

Hi 👋 I'm Simon, the indie dev behind Solo Tuna.

By day, I work as a .NET developer. In the early mornings and on weekends, I build the Mac apps I've always wanted to use. I created Solo Tuna as a home for these ideas — focused tools that save time, reduce friction, and feel right at home on macOS.

Have feedback, ideas, or just want to say hi? I'd love to hear from you.
