Part Prep

Handwrite your markings. Export publisher-quality parts. Part Prep is the ultimate sheet music preparation app built by a music educator, for music educators and players. Write fingerings and shapes using your Apple Pencil, and Part Prep instantly turns them into clean, professionally typeset, print-ready parts. Students can't tell your fingerings from the publisher's. SMART HANDWRITING RECOGNITION • Write fingerings by hand → Part Prep instantly converts them to clean type and learns your handwriting over time (100% on-device & private) SMART SHAPES • Draw rough lines, brackets, arrows, slurs, hairpins, or half-step markers → watch them snap into clean vector graphics. Long-press to tweak with handles STAMPS • Dynamics (ppp–fff), articulations, bowings, pizz./arco: tap to place and resize easily NOTE NAMES • Tap-to-place note name stamps with letters inside noteheads, sharps and flats included: perfect for beginners & accommodations, plus plain noteheads for sight-reading practice FREE TEXT FOR ANYTHING ELSE • Boxed rehearsal marks, reminders, multi-line notes, etc. HIGHLIGHTERS • Sized to the staff, with adjustable opacity: a dyslexia-friendly reading aid! SEMANTIC COLOR SYSTEM • Assign colors by string or voice (plus black and white) with saveable favorites banks. Swap colors across entire selected passages in a single tap DIGITAL WHITE-OUT • Layer white ink over publisher mistakes or awkward dynamic placements, then typeset your new markings directly on top YOUR PARTS, PROTECTED • The original PDF is never modified. Every marking lives on its own layer: you can erase, edit, move, resize, and recolor forever EXPORT OPTIONS • Marked: the part with all your markings, print-ready • Typeset: your typeset markings only, handwritten ink hidden, white-out preserved: for parts that look publisher-printed • Clean: the untouched part, for handing out fresh copies • Marked + Clean (2 files): post both to Google Classroom, print both for class, etc. • Multi-Part PDFs: label individual pages inside a master PDF to export a selection of parts, or all parts, in one tap BUILT FOR REAL TEACHING • Scan paper parts with the camera, or import PDFs from Files, AirDrop, or "Open with" • Organize pieces and parts in a library with backup and restore • Crop, straighten, and scale badly-photocopied parts, non-destructively • A five-minute walkthrough teaches the whole flow on a practice page A VERSATILE LIVE REHEARSAL TOOL Project to a screen and mark live in rehearsal: • Circle that problem low-2 in real time, blown up on the board so even the back row can see it! • Have students make markings and share with class • Conduct live sight-reading practice using blank sheet music and the note stamps FREE + PRO • Everything is unlocked free for your first 14 days - no signup, nothing to cancel • After that, ink, shapes, highlighting, PDF import, and all exports stay free forever. Scanning, handwriting recognition, stamps, and favorites banks are a one-time Pro purchase. No subscription, ever. NOTE FROM THE DEVELOPER: Part Prep was built by me, an orchestra director who was tired of physical whiteout, multiple trips to the copier, resizing woes, and messy handwritten parts. This has been a passion project of mine and combines every feature I've wished for over years in the classroom. While designed with string parts in mind, it is built to adapt to any instrument, whether you need fingerings 1-5 for piano or positions 1-7 for trombone (adjust your digit settings in Settings). If there's a stamp, shape, or feature your classroom needs, let me know in a review or message and I'll add it! TWO PROMISES • Your music and your markings never leave your device. There are no developer servers, and I don't collect any data, nor do I want to, ever. • Absolutely no ads, ever. I can't stand them so my apps don't have them. An Apple Pencil is required for handwriting and drawing. Browsing, scanning, importing, and exporting all work without one.
