Both plans include
- Every desktop feature: musical ideas (form, chord motion, particular chords, color, and two key readings), source notice, stems, scores, lyrics, and the vocal line
- One device at a time — signing in on a new Mac automatically transfers the license
- Offline grace: keep using Prism for up to 30 days without a network
- Stacking renewals: renew early and every remaining day is added on top
