About
AESTIHARMONY
A sole proprietorship in Japan
Run by Daito Iwasaki.
I produce competition floor music for gymnastics, and I build mobile and web applications.
What I do
Gymnastics AI
Designed, built and operated soloAn iOS app that calculates the D-score in artistic gymnastics under the FIG 2025–2028 Code of Points. It includes a rules assistant that answers questions with the relevant article quoted, and a database of more than 800 elements. Available in Japanese and English on the App Store.
Competition floor music
ProductionMusic cut and arranged around the routine itself — accents placed where the tumbling passes and leaps fall, within rules such as the 90-second limit from first movement to final accent. From editing an existing track to composing an original piece.
App and web development
Client workMobile apps in Flutter, web applications and internal tools, websites and landing pages. I also take on updating existing apps and bringing them onto current SDKs. One person from planning through release.
Why music and software
I am a former gymnast who competed at the All-Japan Championships. Since leaving competition I have kept working on the problems the sport still has.
Working out a D-score is heavy work for gymnasts and coaches alike. The Code of Points is intricate, and reading an article correctly takes experience. That is the problem Gymnastics AI was built to solve.
Floor music is the same. Anyone can cut a track to 90 seconds, but knowing where the tumbling begins and where the gymnast needs to breathe is what makes the music fit the routine. Having been on both sides, performing and producing, is the work itself.
The technologies differ, but the thread is the same: turning competition experience into something gymnasts can actually use. AESTIHARMONY is the name that holds that work together.
