We work hard every day to make our apps the best they can be, but the world doesn’t end with the home button. Our work becomes part of a larger experience, and each of our apps is part of a unique set assembled by each user to fit their needs. From the beginning, forScore was designed to be a great sheet music reader and we’ve worked incredibly hard to make that vision a reality. Ultimately, though, each user’s experience with forScore is defined almost entirely by their content. We’ve seen beautifully rendered digital scores and terrible scans of photocopies, and the differences are incredibly important.

We also know that there are plenty of choices out there for musicians, and as the iOS ecosystem continues to evolve, it’s clear that there’s plenty of room for different approaches and styles. We’ve always been willing to tell users to use the best sheet music reader for them, even if it isn’t ours, but apps don’t exist in a vacuum and neither do musicians. Instruments can be enhanced and defined by the complimentary and contrasting sounds of other instruments. Our instrument is forScore, and we want to make music with you.


You’ve worked hard to create the complex tools used by musicians to compose their own music, and now they’re ready to perform. ScoreKit lets you package up your PDF files with all kinds of important metadata, so they can move from writing to playing without wasting time on redundant data entry.

ScoreKit I/O

No sheet music reader is right for everyone. With ScoreKit I/O, your users can share their PDF-based sheet music with forScore users without losing their annotations, metadata, and more. There’s only one restriction: if your app can import 4SC files, it must also be able to export them. After all, share is share.


Just because band members don’t all use the same music reader doesn’t mean they can’t harmonize. Cue, our remote control system, is now available for use in your app so one musician can move between scores and flip through pages while everyone else follows along automatically. Apps that use CueKit can also choose to share PDF-based scores with bandmates over Bluetooth, just like forScore can, and they’ll even work with our standalone Cue app.

ScoreKit and CueKit are available as iOS frameworks, free to use, and both include ample documentation and sample apps to demonstrate their key features. Get in touch with us below and we’ll send you everything you need to get started.


Our time is best spent continuing to develop forScore for iOS, but we know there are many alternatives out there. If you’re a developer working on a sheet music reader for other platforms, we’d love to talk to you. Partner with us to make our apps more compatible with each other, join us to make something even bigger, or just say hello and ask us about our work.

If you make another sheet music reader for iOS, we’d love to talk to you too. There are a lot of mature choices out there for musicians, and there’s plenty of room for the kinds of collaboration that benefit all of us. We know no one app will ever be perfect for everyone, and we don’t ever want people to feel locked in. That’s why we designed forScore around PDF files, after all, and we think that was just the start.
