In their own words
DuetStudio
DuetStudio is a web-based studio management service for private music teachers, covering scheduling, lesson notes, practice assignments, invoicing, and a student portal. Teachers can set one-off or recurring lessons, track attendance, manage cancellations, and send automatic morning-of email reminders. Notes can be shared with students and parents or kept private. Students use an emailed magic link without a password to see upcoming lessons, assignments, practice logs, and shared notes; they can log practice time and track completion. Online invoice payments run through Stripe, while teachers can list Venmo, Zelle, or Cash App details. DuetStudio says it takes no share of lesson payments. The free plan includes manual invoicing; Pro costs $120 a year, billed annually, and adds automatic invoicing, a music library, practice analytics, repertoire tracking, and a public booking page. Organization costs $208 a year, billed annually, requires at least two seats, and is marked coming soon. The responsive web app works on phones and tablets, but there is no native mobile app. Students must currently be added manually because import is unavailable.
