Indie apps,
made with care.

I've spent twenty years building systems for other people, from NFT art marketplaces to Ethereum rollups. These days I'm also making things of my own: two little Mac utilities that live up in the notch, and an astrology calendar for your phone.

Apps

Things I'm making

Two small utilities that live in your Mac's notch, and a bigger one about the sky. All of them sweated over down to the spring curves. The Mac apps have no networking code at all, so your stuff stays on your Mac.

xcv app icon

xcv

A clipboard manager that lives in the notch.

Coming soonmacOS 15 or later

The xcv panel dropped down from the MacBook notch. It shows recent clipboard items as cards (an image, a colour swatch, a Swift snippet and a link), each marked with the app it came from and how long ago it was copied. A search field sits above, with History and Pinned tabs, and type filters below.
Press the shortcut and the notch springs open with everything you've copied. ⇧⌘V

  • Springs from the notch

    One spring morphs the notch into a panel of cards, newest first. No notch? It hangs from the top edge, or slides in from any side of the screen.

  • Pastes where you were

    ↩ pastes straight into the app you came from, ⌘1–9 grabs any of the first nine cards, and plain-text paste is one modifier away.

  • Knows what you copied

    Text, links, images, files and colours each get a real preview and the icon of the app they came from. Search, filter, pin, drag out, or Quick Look with Space.

  • Private by design

    Sandboxed with no network access. Anything a password manager marks as concealed is skipped, and you can exclude any app you like.

Percolate app icon

Percolate

Keeps your Mac awake, one sip at a time.

Coming soonmacOS 14 or later

While it's on, a little cappuccino tips toward the notch for a sip. The timer is live: it started when you opened this page.

  • One click

    Click the cup in the menu bar to start or stop. Right-click for the menu. That's the whole interface.

  • A cup that sips

    The notch grows like a Dynamic Island, the cup drinks from it every few seconds, and your uptime sits on the other side. Four sips to a cup, then it refills.

  • Awake from login

    Turn on Open at Login and Start Percolating When Opened, and your Mac stays awake from the moment you sign in.

  • Light as foam

    Built on macOS's own caffeinate. The animation runs in the system's render server, so Percolate idles at about 0% CPU. No notch? It draws its own.

Astrolical app icon

Astrolical

Your cosmic calendar companion.

Beta on TestFlight iPhone · Android soon

Astrolical's transit timeline for a week in July 2026: each sky event is a pill of planet and aspect glyphs, with an arrow running across the days it's active. Astrolical's home screen: an advisory for an intense energy period, today's new moon at 29°49′ Cancer in the 12th house, the next new and full moons, and a retrograde watch listing Mercury and Neptune with exact degrees and houses. Astrolical's calendar for July 2026 with Tuesday the 14th selected, listing that day's transits to the natal chart with exact times.

  • Precise, not vague

    Every screen is drawn from live ephemeris data: exact degrees, natal house placements, retrograde stations and void-of-course windows.

  • Transits you can read

    A week of sky events in glyph notation, and your month as timeline bars, so you can see what's coming and plan around it.

  • Your chart, drawn properly

    A vector birth chart with canonical glyphs, orb-weighted aspects, and every cusp and degree placed with astronomical precision.

  • Go deeper with Pro

    AI chart interpretations, synastry, composite and progressed charts, solar returns, and alerts before major transits hit your chart.

About

I'm Ryan, a technical leader and builder with twenty years at the intersection of systems, craft and curiosity.

I led engineering at SuperRare, one of the first NFT art marketplaces, from the Rare Protocol contracts to the platform behind them. I've since built next-generation Ethereum infrastructure with init4 on Signet. Through Cedar Inventive, I design, build and run software for schools, non-profits and local businesses. My own apps are where I get to sweat the details just for fun.

Away from the keyboard you'll find me on the air as a ham radio operator (VA3RYC · KO4YVB), tinkering with electronics, or working with my hands. I've also volunteered in emergency medical response and Waldorf education.
