I design software by day and chase light above treeline by weekend.

I’m Rowan, a designer and developer in Bellingham, Washington. I run Switchback Studio, a two-person practice that builds tools for outdoor brands, parks groups and anyone who works where the signal drops. Most weekends I’m above treeline with a film camera.

    What a 35mm prime taught me about interface density

    One focal length for a whole summer made me stop zooming and start walking. Fixed constraints do the same thing for a dense screen: fewer choices, closer looks, and a layout that earns every inch it keeps.

    Shipping a map app that works above treeline

    Vector tiles, a 40 MB budget and a battery that has to last four days. What we cut, what we kept, and the one test we run on every release before it goes anywhere near a trail.
