About
Founder of Ark Co., Ltd. One developer, one dog, one PC. We are developing tools that leverage our experience living in Japan, a country prone to natural disasters. survivalOS — disaster preparedness, two things in one app. A survival calculator: how many days can you live on what is already in your cupboard? It counts calories and water together, including the water it costs to cook. A knowledge base: 178 survival tips otherwise scattered across government PDFs, gathered in one place. 79 verified against the original agency, the rest labelled unverified rather than dressed up. Offline. No account, no ads. ANZEN — crime prevention, built on the same idea. Safety advice exists somewhere, but never where you are when you need it. Also building small workflow tools.
