About
Built to last, at a sustainable pace.
One developer, from planning to store review to updates.
Founder / Solo DeveloperAfter four years as an enterprise application engineer, I went independent to build software at my own pace. Every Abolabo app is planned, designed, coded, submitted and maintained by one person.
Since May 2026 all new titles are built in Flutter and released on iOS and Android at the same time. Earlier Android-only apps stay supported.
I live in Tajimi, Gifu, a pottery town that once recorded Japan's highest temperature. I also grow around fifty fruit trees, and the long-term plan is to open an avocado orchard here. The apps are what keep that plan going.
