Hollowfield
Collective
A small collective making apps about paying attention to things.
Folklore, sound, and the water, so far. The through line is that each one asks you to notice something you would otherwise walk past, and gives you a reason to go outside and look.
Everything here is built by a very small number of people. There is no roadmap and no funding, and things ship when they are good. One of them is already out and free.
What we've made
-
Hollowfield Institute
iOS Sept 2026A field guide to real American cryptid folklore. Photograph where you are and the Institute develops the picture with something in it that was not there when you pressed the shutter. Forty legends, honestly sourced, including the ones that turn out to be documented hoaxes.
On the App Store in September 2026. hollowfieldinstitute.com
-
Tone Twin
Web In betaA tone companion for guitarists. Describe a song and it works out the target tone, then translates it into knob-by-knob settings for the exact gear you already own.
-
Whale Watch PNW
iOSCetacean sightings in the Salish Sea, in real time. It watches the Acartia network and pushes an alert when orcas, humpbacks, greys, minke or porpoises are reported near you, filtered by the species you care about and how far you are willing to drive.
On the App Store, free.
Soon
Taking on work
The collective will shortly start taking on small app projects and ideas from other people, alongside non-profit work. Small in scope, made properly, and the kind of thing that would not otherwise get built.
If you have something, write and describe it.
