We wanted software that feels calm. Tools that stay out of your way, keep your data yours, and look beautiful doing it. So we started making them. We're small team of two, designing and building, one product at a time.
Building softwares
that respect your time
Where others add noise, we leave silence.
Your mind deserves tools as gentle as your best ideas.

The Wall of Love
Kind words from the people using our tools.
LeedPDF "It's really cute 💚 the drawing works well with my Apple Pencil."
Lina Heinz
Web Developer PinkRain "Love the design, it actually looks fantastic. A design I could rest my eyes on."
Leif Strand
Builder Cristalyse "It took all of 10 minutes to replace an old integration of community_charts_flutter with a working Cristalyse implementation, and way, way less code."
Colin Young
Developer
Glucose "Oh, that looks cool! Thanks, man, exactly what I needed! 💪"
Max Wang
Builder DoublOne "The attention to detail across all their products is rare. You can tell a small team built these with real care."
Priya
Startup Founder Golden Day "GoldenDay is genuinely one of the apps I use the most. Really good for both collecting and finding inspiration."
Clara
Graphic Designer "Accessibility is such a pain to get right but it's often a requirement. So glad Hux UI makes it built-in."
Sarah
Engineering Manager CaraML "I cancelled all my other AI subscriptions and now only paying for CaraML. Definitely saving a lot of money."
Yuna
