About SimpleBit
SimpleBit is an independent software studio. We believe the best tools are invisible — they get out of the way and let you do your best work.
We ship one thing that works perfectly rather than ten things that work adequately.
Every design decision asks: does this help the user think, or does it interrupt them?
User data is not a product. We build tools that work without surveillance.
We maintain what we ship. Apps should get better with time, not abandoned.
"Software should feel like a natural extension of thought."
