The studio
Silkway Studio is one person making software, mostly for Apple platforms. The same care runs through every product: native interfaces, fast layout, and details that feel like they belong on the device.
The name comes from the Silk Road, the old routes that connected distant places. The products are connected the same way: one studio, one thread, and each product a world of its own.
