The Marrowyn

The Marrowyn is a dark, focused workspace for designers and makers — two precise tools in one calm dashboard, with no accounts and no clutter.

Ratio Studio handles dimensions. Type any two of width, height, or an aspect ratio and the third is solved instantly, shown next to a live preview rectangle so you can see the shape before you commit. Tap a preset like 16:9, 4:3, 1:1 or 21:9 to fill the ratio in one move, or drop in two pixel sizes and let it reduce them to their cleanest ratio. Any result can be saved or shared.

Palette Forge handles colour. Pick a base hue with the brightness and saturation sliders, then choose a harmony — complementary, analogous, triadic, tetradic or monochrome — and five balanced swatches are built for you. Tap a swatch to copy its hex code, or save the whole set.

Everything you keep lands in the Library, where saved dimensions and palettes sit side by side, ready to reopen, copy or share again. Choose an accent colour, switch haptics and click sound on or off, and work in landscape on iPhone.

No sign-up, no ads — just two clean tools that each do one job well.
