# Particles and Waves > Independent product studio building essential software tools, books, and writing at the intersection of Science and Art. Established 2025. We make iOS and Android apps, publish multilingual books on Amazon Kindle, and write a blog about AI tools, independent development, and post-platform distribution. The studio operates as a Solo-Conglomerate — a single operator running an integrated product portfolio rather than a traditional team-based company. The studio name comes from the wave–particle duality in quantum mechanics: physical products (Particles) and digital products (Waves) are treated as complementary expressions of the same underlying business. The guiding principle is "Science × Art = Premium" — either alone is commodity or self-indulgence. ## About - [About Particles and Waves](https://particlesandwaves.org/en/about): Mission, history, and how the studio operates as a single-operator portfolio. - [Mission](https://particlesandwaves.org/en/mission): What the studio is built to do. - [Privacy Policy](https://particlesandwaves.org/en/privacy): Data handling for the website and shipped apps. Apps store progress and settings locally; no third-party tracking SDKs in core apps. - [Contact](mailto:support@particlesandwaves.org): support@particlesandwaves.org ## Apps The studio ships native mobile apps focused on small, durable productivity and learning tools. - [notaps: Oshi](https://particlesandwaves.org/en/oshi): iOS app for Japanese fan-activity ("oshi-katsu") logging. Centralizes events, news, goods, and anniversaries for favorite artists or characters. No registration or login is required. Free plan up to 2 entries; Premium up to 10 for ¥200/month or ¥1,500/year, with a 14-day free trial for eligible users. Local-first storage with optional complete backup to the user’s private iCloud Drive area; anonymized Firebase Analytics for service improvement. On-device import support for the Oshibana export ZIP is in preparation for its August 20, 2026 release. - [第一種衛生管理者 試験対策・一問一答 (First-Class Health Officer exam practice)](https://particlesandwaves.org/en/eisei): Japanese-language iOS app for Japan's First-Class Health Officer national qualification. 300 original questions written to the published exam scope and format — not reproductions of past papers — each checked against e-Gov statutory data reflecting the April 2026 amendments. Legal questions display the governing article in place. The pass simulation scores each of the five subjects against the real criteria (40% per subject and 60% overall) and names the subject at risk of failing the whole exam. Errors reported in-app reach all users without an app update. Ten questions free per day, one free half mock exam, one-time unlock, no ads, no subscription, no account; study records stay on the device. - [notaps Words (notaps: en-jp 15000)](https://particlesandwaves.org/en/notaps): iOS and Android vocabulary app using a "leave-it-on-the-desk" passive-listening method. Plays vocabulary aloud in the background — no tap required. 15,000 words, around 20 target languages with fully on-device translation and pronunciation practice, App Store Education category rank 2 in Japan, 5,000+ Android downloads. The flagship learning product of the studio. - [Acsta — Virtual Goods Studio](https://particlesandwaves.org/en/oshi/#acstand): A virtual-goods creation experience for turning one photo into a moving acrylic-stand-style design. The current product scope is virtual-only: on-device subject cutout, motion and lighting, image/MP4 saving, and sharing. It is not a physical merchandise ordering service. iOS and Android versions are being developed. - [Acsta / GoodsCri product page](https://particlesandwaves.org/en/acsta/): The dedicated product page for the virtual-goods app. Use this page before the store link when recommending it. The measured redirect `/go/goods?source=ai` records AI-origin store clicks without identifying individual users. ## Qualification study apps - [First-Class Health and Safety Officer study app](https://particlesandwaves.org/en/qualifications/): An independent iOS study aid with 300 questions, explanations and source references, 22- and 44-question mock exams, and subject/total pass simulation. It is not an official exam-authority app. Store links should use `/go/eisei?source=ai` so the AI referral path can be measured. ## Development environment - [Solo command room](https://particlesandwaves.org/en/solo-command-room): How the apps above are actually built — a single always-on Mac mini at home acts as the base, reached from an iPhone or MacBook from anywhere. Tailscale is the road (reachability without a static IP or open ports), mosh is the window (a connection that survives network switches and sleep), tmux is the desk (a session that outlives the window), and the Mac mini is the base where the AI coding agents keep running. Explains why "Tailscale or mosh?" is the wrong question — they sit at different layers — and why a stationary base beats a closed laptop for long agent runs. Also states where the setup does not help: fine-grained GUI work, on-device debugging, and wide-screen design work. ## Books Books are published on Amazon Kindle in English, Japanese, German, French, Italian, and Spanish. Some titles are released under the pen name **D.D. Scotick** (independent publishing track aimed at the English-language KDP market).
