A sleep log for bodies that don't run on a 24-hour clock.

Circadia 24-hour dial
plate icircadia24h dial

Not every sleep log is built for rhythms that drift past a 24-hour day. Circadia is Dayah's answer: it takes the pattern you actually have, finds your real drift, and forecasts the next window instead of pretending you will fall asleep at eleven.

§02 - apps

In the workshop.

Circadia leads, with Talons close behind; the rest splits into launchable apps, active prototypes, and substrates O+K is dogfooding before offering outward.

Open alpha

Circadia

A sleep drift log for Non-24 rhythms, forecasts, and irregular rest patterns.

Free alpha

One Month of Open Alpha

One month into open alpha, Circadia has moved from a tool I built for my own impossible sleep into an app with enough real N24 data to make the research side feel less theoretical. The Community tab is live, Jon replaced the particle filter forecast with a tag-aware Kalman-IMM model, and the app now has enough users to expose the administrative layer under health software: platform rules, security audits, server costs, and the boring financial reality of keeping something useful alive.

What Is Non-24-Hour Sleep-Wake Disorder?

A plain-language guide to Non-24-Hour Sleep-Wake Disorder (N24): what it is, what "free-running" means, why sighted people get it too, how it's diagnosed and managed, and why several of its stranger features — marathon wake periods, sleep debt that won't clear, a sleep window that slams shut — are completely normal for the disorder.

Two τ Changes Today, and the Bug I Caught On My Own Data

Why your τ tile might look a little different from this morning — and why the change is mostly the math finally admitting it can't fit a 30-hour cycle onto a 24-hour clock face.

One Number Is Never the Whole Story

Why Circadia lets you change the math behind your sleep — and why my own settings look nothing like the defaults. Featuring a very bad Airbnb, a fourteen-hour lurch, and the embarrassing number of hours I do not spend asleep.

§06 - owl + kestrel

The two of us.

Jon builds the systems; Dayah builds the bodies. Also married.

Kestrel@spicystrippa
Flexibility teacher, model, and builder

Flexibility teacher, model, and builder of tools for bodies and rhythms that do not fit the default template.

§07 - questions

Questions we get.

01

What is Owl + Kestrel?

A two-person workshop and estate shell. Jon builds software and infrastructure; Dayah teaches flexibility and built Circadia. O+K is also the first customer for family products like Nest, Chirp, Plumage, Pigment, and Quill; Quill's standalone source MVP combines social notes, longform publishing, and optional verified history.

02

How do I book a class with Dayah?

Bookings is the current place to join the waitlist. The schedule is still firming up, so this is not a live class calendar yet.

03

Are the apps free?

Pricing and access are product-specific. Circadia is in open alpha, Talons is free during its alpha, Conduit and Glideslope are alpha downloads, and several substrates are still dogfood or contract-first rather than packaged for public purchase.

04

How do I keep up with new things?

Join the updates list or follow the journal.

05

Why Owl + Kestrel?

It is the two of us: a nocturnal systems-builder and a sharp-eyed teacher. One small workshop, two sets of projects.

§08 - updates

Updates when there is something to say.

New apps, posts, and class openings from Dayah. This preview signup only asks for an email address.
