PromptersBox is an opera library built by a working singer, staged for the people who actually have to sing it. Every opera is hand-set into act-books, line by line, so you always know what you are singing, how it sounds, and what it means. THE SEASON A growing library of operas, published in two editions: - Full Study: libretto, IPA, word-for-word translation and dramaturgical analysis, with directorial notes, character dossiers and performance pitfalls. - IPA & Translation: libretto, IPA and word-for-word translation, ready fast. New productions join the season all the time, and you set the queue. Request an opera, or move one already in progress up the bill. FIND YOUR ROLE Type your role and land on your first line. Every role in every act is mapped to its entrances, so the Playbill takes you from a character's name straight to the music they sing. THE READER - Tap the page edges to turn. - Day and Night paper, and the reader keeps your page. - Search the libretto itself: the sung lines, including transliteration for operas not printed in the Latin alphabet. - Your repertoire shelf keeps your books ready offline. FREE SAMPLES Every act-book opens five pages free, set at a real moment in the score, so you can read before you pay for anything. THE FULL SEASON One subscription opens every book in the library, starting with a 3-day free trial. Subscriptions renew until cancelled and can be managed in your App Store account settings.

Verdict
The clearest difference is in-app purchases: AR Time at none against PromptersBox's 1. AR Time also leads on update cadence (every 4 days vs every 9 days) and iOS requirement (12.0 vs 17.0). On price, ads and device support there is nothing between them.
