An evening for music teachers — Tracktice. Wednesday 22 July, 7.30 to 8.30pm, CYL Music Studio, 91A Joo Chiat Road, Singapore 427385. Free, small snacks provided, 10 seats.

What it is: a short, informal sharing session — not a hard sell. I'll walk you through Tracktice on the projector: what it does, and how a flute teacher ended up building it. You can try it on your own phone while I go, and ask anything.

Tracktice is built for a small, specific group: freelancers who teach music. People who want to teach more effectively, speak a lesson summary into their phone for the student and their parents, invoice without chasing, keep lessons, gigs and rehearsals in one timetable, and actually see what they're earning.
