Seven Products in Four Months From One Desk in Tokyo
Between June 29 and October 9, 2026, I designed, built and released seven products from Tokyo: four iPhone apps, two Mac apps and a desktop companion for Claude Code, each released under my own name. This is the dated list, with what each one is, what I wrote, and a link so you can check it instead of taking my word for it.
Why a list
Everyone in design claims to ship. Most portfolios are screenshots of work that a team released under a company's name, which proves collaboration and not much else. A store listing is different. It carries a seller name, a release date, a version history, a privacy declaration and reviews from strangers. It cannot be mocked up.
So when I say I am an AI product designer and design engineer in Tokyo, this is the evidence I would want someone to check. Every date below comes from the App Store or the package registry, not from me.
The seven
1. Glimpse Vision AI
iPhone. Released June 29, 2026, now on version 1.3.5. English, Japanese and Spanish. Point the camera at something and ask, and Glimpse answers out loud in real time, through Glimpse Glasses or the phone alone. No wake word, no menus. I designed the interaction, wrote the iOS app and the streaming pipeline between the camera, the model and the voice, and localized the listing myself. App Store.
2. AnimaEcho
iPhone and iPad. Released July 14, 2026, now on version 1.6. A Live2D companion you talk to, not type at. She listens while you speak and answers in her own voice, in real time, with nine backdrops that carry a live weather layer. The whole app has no keyboard. I built the character pipeline, the speech to speech loop and the subscription. App Store, case study.
3. Ground Control Chat
iPhone, plus a command line package. The npm package shipped July 16, 2026 and the app followed on July 25, now on version 0.1.11. Every Claude Code session running on your Mac appears as a small pixel pilot on your phone: cyan while working, lavender while idle, pink when it needs you. Tap one and you are inside the conversation. One command pairs the Mac, there are no accounts, and the relay is end to end encrypted so it cannot read a byte. I designed the pilots, wrote the iOS app, the relay and the package. App Store, npm, case study.
4. Nightwatch
Mac App Store. Released September 14, 2026, now on version 1.0.3. A menu bar app that keeps the Mac awake for exactly as long as you ask, with a countdown in the bar. It exists because overnight coding agents die when the Mac sleeps. Small, deliberately. Mac App Store, the article.
5. Yubi
macOS, direct download, September 2026. A voice assistant in the menu bar. Hold a key, say what you need, and she types it, clicks it or answers it inside the app you already have open. Dictation runs on the device. The agent reads the accessibility tree of the front window rather than taking screenshots, which is a privacy decision and a design decision at once. I wrote the Swift app, the Japanese site, the account and billing backend, and the metering. yubichan.ai, seven things to say to it.
6. Reshito
iPhone. Released September 23, 2026. A household ledger for Japan: you punch in the receipt amount like a calculator, pick a category built for Japanese life (konbini, groceries, the subway), and the home screen shows the month and the last seven days. Six months of reports, CSV export, Japanese and English, and a separate space for sole proprietors with an invoice registration number. I built it because the apps I tried were designed for a different country. App Store.
7. Koharu
macOS, direct download, October 2026. A token accountant for Claude Code: an animated office worker who sits on your desktop and keeps the books on what your sessions are spending, with fifteen outfits because I could not stop. It is the smallest product on this list and the one I enjoy most. lastres.ai/mods/koharu.
What is not on the list
AnimaNext, the NFC business card, has been shipping since 2024 and kept getting work this year: a Wallet pass, a lighter design, Spanish and Japanese end to end, and a checkout that delivers to 245 countries. It is my own product too, and the one that made me stop measuring my value in handoffs.
Client work ran through the same months and most of it carries someone else's name, which is as it should be. The cases I can show are on the work page: a film studio's site that went from design to launch in four weeks, brand work for Japan's first regulated yen stablecoin, and a year of brand, product and growth for an AI infrastructure company.
One more app is in App Store review as I write this. It is not on the list because it is not live, and the whole point of the list is that everything on it is.
What it took
I want to be honest about the method, because "seven products in four months" invites a wrong conclusion. AI did not write these apps. I use Claude Code every day and I hold the Claude Partner credential for it, and what the tools removed was the cost of trying an idea, not the cost of being right. I have written about the parts that did not get faster, and they are the same parts that always decided whether a product works: the error states, the subscription that has to restore, the copy in a second language, the moment the model is wrong.
What made the list possible is the thing the title of this site says. One person did the product decision, the interface, the code, the store listing and the support, so none of those steps waited for another. That is the whole argument for the design engineer as a role, and I would rather make it with dates than with adjectives.
Why from Tokyo
Three of the seven exist because of this city. Reshito is built around a Japanese receipt. Yubi speaks Japanese first and her site is Japanese first. Glimpse was localized into Japanese on day one because the people I test it with are here. Tokyo is the city that named the design engineer, and it is also a market where very few people hold the role in software. That gap is where I work.
If you need someone who can do this for your product, here is what to check before you hire anyone, me included. The press kit has the bios and photographs, and the contact form reaches me directly.
