Hisashi Space

Apps

Ten products, one person. Five for the Mac and five on the web, every one of them designed, written, signed and shipped by me.

On the Mac

Notarized by Apple, and none of them asks you to make an account before you can try it.

SpaceDeck

macOS · $129 one-time

Mission control for every app you live in.

A macOS browser built around the fact that most people hold more than one account of the same service. Gmail, Claude, Notion and Slack each get an isolated space, so three work inboxes stay open side by side instead of taking turns. One notification bell, per-app zoom and mute, a built-in terminal. No account required.

Kagemusha

macOS · Free for 3 apps

Turn any website into a standalone macOS app.

Wraps a website into a real app with its own icon, its own window and its own profile, powered by whichever Chromium browser you already use: Chrome, Brave, Edge, Vivaldi. Ships with 240+ presets.

Caltimate

macOS · Free tier

A native Mac calendar that syncs with Google Calendar.

Plain-language and voice entry, meeting links detected automatically, real travel time from real map data, and tasks in the same grid as events. Japanese-language site for now.

Coming next

Named, in progress, not out yet.

Atriens

macOS · in progress

File management for working with AI.

Your folders, your terminal and your AI in one window, instead of running Obsidian and Cursor side by side. When an agent stops and waits for an answer, you can reach your Mac from your iPhone and keep it moving.

Ultenix

macOS · in progress

A terminal that works with you, not just for you.

A terminal emulator with an AI dock built in. Imports your iTerm2 arrangements, lets you pick the monospaced font and the colours you actually want, and puts Claude one keystroke away from the command you are about to get wrong.

On the web

The Mac apps are the newer half of the work. These have been running for years, and the oldest of them pays for everything else. They are in Japanese.

@SOHO

Web · Free to use

A freelance marketplace with 300,000 members.

Japanese companies post work, freelancers take it, and neither side pays a commission. Started in 2004 and the largest of its kind in Japan within four years. Still one developer.

Rizaflow

Web · Paid plans

Bookings for businesses that get paid in person.

Salons, coaching, yoga, clinics and schools. Takes the booking, sends the reminder and the thank-you note, and gives every customer a page of their own. Existing customer lists import from CSV.

Pinateca

Web · Free up to 5 people

Halict

Web · Paid plans

From form submission to answered, in one screen.

Tsudoo

Web · Free tier

One place for a class, a club or a neighbourhood.

Announcements, a schedule with attendance, chat, photos and video, all in one group notebook. Built for classes and courses, and it works the same way for a PTA or a residents association.
