Adagio vs OPS

Adagio is a web and mobile app for music teachers managing classrooms or studios and keeping students involved between lessons. Teachers can schedule lessons, assign homework, keep class or lesson notes, and track practice time. In the Practice app, students can log sessions, notes, and personal to-do lists. They can also comment, use a social feed, and earn levels and points for practice sessions. Students can opt in to share practice sessions, assigned homework, goals, and notes with teachers. Adagio includes student records, attendance tracking, a student portal, and online payments. Invoices can be created manually or after a completed lesson, with PayPal payment options and email reminders for overdue bills. Its free plan is free; Premium is $5 a month. The Organization Plan supports multiple teachers and classrooms, administrative oversight, and shared class access. Adagio is available on Android, iOS, and the web.

OPS is a management platform for orchestras, bands, and music schools, bringing scores, member records, instrument inventory, accounting, and documents together. Its score library uses OCR to identify scanned scores and create a separate PDF for each instrument part. Member management supports custom fields and groups, bulk imports and exports, and optional user accounts. Instrument records can include loan contracts, repairs and maintenance, QR labels, photos, and waiting lists. The music school module handles enrolments, courses, attendance, grades, report cards, and a parent portal. Accounting follows the French Plan Comptable Général for associations and includes FEC export. Setlists can be shared with a public link or embedded on a website; ensembles can cross-share scores through the Mediathek. OPS Scores is an iPad app with Apple Pencil annotation, offline access, and Bluetooth page-turn pedal support. OPS Mobile for iPhone supports QR scanning, score browsing, inventory and loan management, member lookup, and an accounting overview. The maker says data is hosted on OVH servers in Strasbourg, stays in Europe, and is GDPR-compliant. Events, calendars, and in-product communication are marked as coming soon.
