Welcome to Indie App Spotlight. This is a weekly 9to5Mac series where we showcase the latest apps in the indie app world.
If you find yourself playing an instrument with sheet music, flipping the page often requires you to stop playing to turn it. CueFlip solves that. You can teach it how you play a song, then it can turn the page for you whilst listening.
Highlights
CueFlip doesn’t just assume how it should turn the page — you can explicitly teach it how to. That starts with either a live rehearsal or a recording you can share with it. Then, you mark the turns.
CueFlip also has a built-in dictionary where you can look up terms on a page to learn how the composer meant them to be played, rather than having to guess. Many of these terms appear in other languages, but CueFlip offers built-in translation across up to 13 languages. The app covers over 20,000 terms and can pull terms from scanned scores as well.
Lastly, CueFlip has a clever Face ID feature. Winking with your right eye manually turns a page forward, while winking with your left eye goes backwards. CueFlip also works with manual Bluetooth page turners in addition to automatic turning, for situations where you need that option.
The Story
Here’s why 15-year-old classical guitarist Yuze Pan from Beijing decided to build CueFlip:
I play in the Primal Guitar Quartet, and page turns kept breaking up our rehearsals. Paper means taking a hand off the strings, a pedal or a wink is one more thing to remember in the middle of a phrase, and timed turns can’t follow a performer who speeds up and slows down. My first attempt, in 2025, didn’t work. In May 2026 I started again, this time by reading the research on audio alignment, and brought every new build to the quartet’s daily rehearsals.
