Notarium: Sheet Music

Notarium is a sheet music app for musicians: a library for PDF and image scores, a clean full-screen viewer, setlists, practice tools and a notation editor — all of it working offline.

📚 Library
• Import PDF files, images, MusicXML (plain or compressed), ChordPro and text — or scan printed pages with your camera
• Search across titles, composers, artists, genres and tags
• Group by composer, genre, collection or what you opened recently
• Collections and filters by genre, key and difficulty
• List or cover grid, alphabetical index for large libraries

🎼 Viewer
• Full-screen reading with minimal interface
• Page modes: single page, two pages side by side, vertical scroll and half-page turn
• Crop margins to make the music larger on screen
• Bookmarks and link points — jump instantly at repeats and codas
• Night mode with inverted colors for dark stages
• Your last position in every song is remembered

✏️ Annotations
• Pen, highlighter and text notes directly on the page
• Two layers, eraser and undo
• Original files stay untouched — markings are stored separately

🎶 Setlists
• Build your program by drag and drop
• Performance mode: continuous page turning through the whole setlist

🥁 Practice tools
• Metronome: 30–300 BPM, accented downbeat, visual beat indicator
• Audio player: attach recordings to songs, slow down without changing pitch, A–B loop for tricky passages

🎸 Chord sheets
• ChordPro and plain text files with chords over the syllable you play them on
• Transpose the whole sheet by semitones with musically correct spelling
• Adjustable text size, choruses and tab blocks laid out properly

🎹 Notation editor
• Write music from scratch: notes, rests, accidentals, ties, dynamics, lyrics
• Select several notes at once and edit or transpose them in one step
• Properties panel for the selection; two voices and parts; key, time signature and clef settings
• Transpose by any interval with correct spelling
• Playback with piano sound and a moving cursor
• Import MusicXML; export MusicXML, MIDI, PDF and PNG
• Engraving powered by Verovio

📷 Scanner
• Scan printed sheet music straight into your library
• Automatic edge detection and perspective correction, batch scanning of up to 30 pages
• Scanned pages are stored in your library as images

⚙️ Yours to keep
• Light, dark or system theme, Material You colors, and an interface in 44 languages
• Back up your whole library — scores, markings, setlists — into one file and restore it on another device
• See exactly how much space the library takes and clear derived caches

🔒 On your device
• Reading, marking up and writing music work offline; the scanner and buying Pro go through Google Play
• Your scores, markings and recordings are kept in the app’s own storage on your device

💳 Free, with an optional Pro
• Everything you need to play from the screen is free: the library, the viewer, annotations, setlists and performance mode, the metronome, the audio player, the scanner, the notation editor, and export to MusicXML, MIDI, PDF and PNG
• Notarium Pro adds what teachers and arrangers need on paper: PDF with a title page and printing margins, PNG at high resolution, a whole setlist as a single file, plus stamps, shapes, custom palettes, extra annotation layers and exporting a page with your markings on it
• Pro is a monthly or yearly subscription, or a one-time purchase. Google Play handles the payment; your library stays where it was

Who is it for?
• Performers: full-screen viewer, setlists, night mode
• Students: metronome, slowed-down playback, A–B loop, annotations
• Teachers: scan exercises, mark them up, keep them organized
• Composers and arrangers: notation editor, transposition, MusicXML and MIDI export
