Made with a different kind of vision.

My eyes aren’t great.My apps are.

I got tired of squinting at my phone.
So I started making apps I actually enjoy using.

Find your next little ritual

Small pleasures. Clearly made.

Two apps. One point of view.

Sudoku Studio

One square
at a time.

A good puzzle should challenge your mind. Reading the board shouldn’t be part of the challenge.

  • Big numbers and distinct colors
  • Notes you can actually see
  • Themes that feel right for your eyes
Open Sudoku Studio

Zentrist

One night
at a time.

A fan, a little rain, a chorus of crickets. Make the sound that feels like winding down to you.

  • Blend ambient sounds your way
  • Shape your mix with effects and EQ
  • Big controls for glasses-off bedtime

A little personal.

Built for my eyes.
Maybe yours too.

I’m Ransolo—the person behind Ransolo Dev. I have less-than-great eyesight, and I like a good puzzle and a little background sound at bedtime.

Tiny numbers, crowded screens, controls I have to hunt for—I wanted something easier to live with. So that’s what I’m building.

Apps with room to breathe. Things big enough to see. And the details that make you want to come back tomorrow.
