About KIYODO

An engineer and writer based in Tokyo, Japan. By day, building software (web, automation, AI tooling); on the side, running indie SaaS products and embedding generative AI into operational workflows. Always insists on hands-on testing before forming an opinion — first-hand experience over secondhand reporting.

Topics covered

  • Building and running iOS apps solo (the task, the route, oshi)
  • Measured revenue and costs — ads, subscriptions, build fees
  • Failures and fixes — App Store review, outages, data loss
  • Using Claude and other AI dev tools in real development

Editorial stance

First-hand information only, from apps I build and run myself. Numbers are ones I measured; guesses are labeled as guesses. Anything involving ads or affiliate links is always disclosed as PR.
