What CueFlip does, how it follows you, what it needs and what it costs. Setting up a piece and correcting a turn are in Support.
What CueFlip does
What is CueFlip?
CueFlip, sometimes written Cue Flip, is an app for iPad and iPhone that listens to you play and turns the pages of your sheet music at the moment you reach them. You teach it a piece once, by playing it through while it records; from then on it follows you in real time, so both hands stay on the instrument.
Is there an app that turns sheet music pages automatically?
Yes. CueFlip is an automatic page turner for iPad and iPhone: it listens to you play and turns each page of your sheet music as you reach it, without a pedal and without a touch. It does not read the notation and does not depend on a fixed beat; it follows the way you actually play, through repeats, first and second endings and D.S. jumps.
How can I turn pages hands-free while I play?
Let CueFlip turn them. Teach it a piece once: play it through while it records, and mark where each page should turn. From then on every turn happens by itself as you reach it, so both hands stay on the instrument. If you would rather turn pages yourself, a Bluetooth page-turner pedal or any keyboard works too.
How does CueFlip know when to turn the page?
It does not read the notation on the page. When you teach it a piece, it records you playing it through and learns what the music sounds like at each moment, together with the points where you want the pages to turn. During a performance it listens, finds your place in what it learned, and turns each page as you approach the point you marked.
What is score following?
Score following is the name music research gives to a computer that listens to a live performance and keeps track of where the player is in the score. The idea goes back to 1984, when Roger Dannenberg and Barry Vercoe each described a computer accompanist that followed a live soloist. CueFlip puts score following to work turning pages: it does not read the notation, but compares what it hears with a recording of you playing the same piece, a method called real-time audio alignment, and turns each page at the point you marked.
Does it follow repeats, first and second endings and D.S. jumps?
Yes. What CueFlip learns is the route you actually play, so it follows repeats, first and second endings and D.S. jumps without being told about them, turning back to an earlier page when the music does.
What if I play faster or slower than when I taught it?
CueFlip times each turn to the tempo you actually play; it does not depend on a fixed beat. If pages start turning too early or too late, the usual cause is a large difference in tempo from the recording the piece was taught from. Teach it again at a tempo closer to the one you now play at, or adjust where each turn is marked without re-recording.
How is CueFlip different from auto-scroll?
Auto-scroll moves the score at a speed set in advance, so it carries on when you slow down, hold a fermata or take a repeat. CueFlip does not depend on a fixed beat: it listens, follows the tempo you actually play, and turns each page when you reach the point you marked, through repeats, first and second endings and D.S. jumps.
How is CueFlip different from apps that turn the page when you wink, nod or look?
Those apps watch you through the camera and turn the page when you make a gesture. CueFlip needs no gesture at all: once it has learned a piece, it listens to the music and turns each page as you reach it, so your attention stays on the music and both hands on the instrument. If you want to turn a page yourself, a Bluetooth page-turner pedal or any keyboard works too.
Do I have to tell CueFlip what instrument I play?
No. It learns each piece from a recording of you playing it, and follows what it hears. For the most dependable turns, record at a tempo close to the one you will perform at, in the room and with the instrument you will perform with, and place the device where the instrument reaches the microphone clearly.
Do I need a Bluetooth page-turner pedal?
No. Once a piece is learned, the pages turn by themselves, without a touch. If you have a pedal, Bluetooth page turners from AirTurn, PageFlip, iRig BlueTurn and Donner work as soon as they are paired, and any keyboard turns pages too; while you teach a piece, a press of the pedal marks the turn.
Can CueFlip turn pages in a live concert?
Yes. On 8 August 2026, the day after its release, Primal Guitar Quartet performed with it at Blue Note Beijing, its first use in a formal concert, and it has been used in many concerts and rehearsals since. For a concert, teach it the piece at a tempo close to the one you will perform at, in the room and with the instrument you will perform with.
Automatic page turns that follow your playing
Which scores can I use?
Any PDF. Choose one from Files, iCloud Drive or the document app you already use; CueFlip keeps its own copy, so the score is there on stage whether or not you are online. CueFlip comes with no sheet music of its own apart from the tutorial score: bring the PDFs you already have.
Can I use CueFlip just to read sheet music?
Yes. CueFlip opens any PDF score and shows it as printed, in Sepia or in Night, with bookmarks for the places you return to; Pro adds Apple Pencil annotations in layers. You need to teach it a piece only for automatic page turns, and you can turn pages yourself at any time with a Bluetooth pedal or any keyboard.
Can I try CueFlip without my instrument?
Yes, with the tutorial score that comes with the app: play its demo recording near your iPhone or iPad, tap Perform, and the pages turn themselves.
Your own pieces are different. Playing a recording back at the app does not work for them, because audio from a loudspeaker no longer resembles a live instrument in a room closely enough to be matched. Test those with the instrument itself.
What it needs
Which devices does CueFlip run on?
iPad and iPhone, with iPadOS 16.4 or iOS 16.4 or later. A microphone is all it needs to listen; Apple Pencil is optional. There is no version for Android or Windows.
Does CueFlip need an internet connection?
No. Following the music and turning pages work entirely offline. A connection is needed only to buy or restore a subscription.
What happens to my recordings and scores?
They stay on your iPad or iPhone unless you send them yourself. There is no account to create, no tracking and no advertising, and the app collects nothing on its own. Nothing reaches us unless you choose to send a page-turn report.
Which languages does CueFlip speak?
English, German, Spanish, French, Italian, Dutch, Polish, Portuguese (Brazil), Russian, Japanese, Korean, Simplified Chinese and Traditional Chinese.
Does CueFlip work with VoiceOver?
Yes. CueFlip supports VoiceOver, Voice Control, Larger Text, Dark Interface, Differentiate Without Colour, Sufficient Contrast and Reduced Motion. The accessibility page says exactly what each one covers, and where the limits are.
Free and Pro
Is CueFlip free?
It is free to download. The free version turns the pages of one score of your own, as well as the tutorial. Pro removes the limit and adds annotations, the metronome, tuner and piano, folders, page editing and live sharing with players nearby.
How do I get Pro?
Inside the app: subscribe by the month or the year, or buy it once and have Pro for as long as you use CueFlip. Prices are shown in the App Store in your own currency. Subscriptions are billed by Apple; manage or cancel them in iOS Settings → your name → Subscriptions.
Can players in an ensemble share markings and a beat?
With Pro, yes. Pair with another device in the same room using a one-time code, and markings appear on both as they are written; the connection runs directly between the devices, with no router and no internet. Ensemble Sync locks every player’s device to the same metronome beat, so the whole group hears the click; the others join with a code.

Who makes CueFlip?
