Opus · Concerts & Opera

Every night at the concert, kept in memory.

Every opera, every symphony, every recital, with its programme, its venue and its performers. Season after season, Opus shows you how much of the repertoire you have already heard live. On iPhone and iPad.

The Opus Calendar on iPad: the next concert on top, the thread of years and the evenings of 2026
The concertgoer's journal

An evening and its programme

That same night or the next day, note what you heard. Opus already knows the works: you only have to pick them.

New performance on iPhone: searching “Brahms” lists the works already seen and those of the catalogue

Logged in seconds

Type “Carmen” or “Brahms”: the work comes from a built-in catalogue of nearly 250 composers, from Monteverdi to Pärt. Add the venue, the conductor, the orchestra and the soloists.

  • Several works in one evening
  • Your own notes, to remember what moved you
  • A work missing from the catalogue? Opus looks it up online, or you type it in
Programme read on iPhone: the Ravel concerto is to check, Opus offers the two possible works

Take a photo of the programme

Opus reads the pages of the printed programme and prepares the evening: works, composers, performers. You check, you confirm. The photos are never kept.

  • Up to six pages at once
  • An uncertain work is flagged to you, never added silently
  • With Apple Intelligence, from iOS 27
The Calendar on iPhone: an evening to confirm, then the next concert and its countdown

Upcoming concerts, up front

Got your tickets? Log the evening in advance: it waits in the calendar, with a countdown. The day after, confirm it with a single gesture.

  • The next concert always at the top
  • A missed evening is removed just as easily
  • Theatre and dance have their place too, without skewing your figures

Show mode on iPhone: the screen dimmed on the night of Tosca
In the hall

Quiet when the lights go down

Show mode dims the screen so you never disturb your neighbours. On concert evenings, it switches on by itself from 5 pm.

  • Day mode, night mode, or your device's setting
  • “Not tonight” pauses it until midnight
