Software I build. Some of it is in the app stores, some runs on my own servers.
MusicGym
A practice gym for wind players. MusicGym generates exercises and routines for your level, renders them as real notation, listens through the microphone and gives live feedback on pitch and timing, keeps streaks and goals, and has an AI coach that explains what to work on next.
It is also made for music teachers, my colleagues. A teacher account links to student accounts and shows how each student practises at home: what they worked on, how often, and where it goes well or not.
Studio Suite
A music lesson management system: students, lessons, scheduling, invoicing and subscriptions, on an open-source ERP foundation. The system I use to run my own teaching practice, packaged so other teachers can run theirs.
