For as long as there has been sheet music, someone has had to turn the page — you, reaching over, or a friend who caught your eye. CueFlip does that job. Play a piece through once so it learns the score. After that, just play: when you reach the last bar of a page, the next one is already there. It is not a timer. Hold the fermata and it holds with you. Take the repeat and so does it. Slow the final four bars as you always do, and nothing moves until you finish. And when it is wrong — one day it will be — tap the edge of the page, as you always have. If it was following well, it steps aside a few seconds, then picks you back up. If it had lost you, that same tap tells it where you are. ◆ TEACHING IT A PIECE Import any PDF you own — Files, iCloud Drive, AirDrop, another app. It opens straight in the reader: read now, teach it when you are ready. To teach it, play the piece through and tap the page edge whenever you turn. That is the whole setup. No instrument to hand? Import a recording and mark the turns as it plays. Turn backwards while teaching and it learns the jump: repeats, D.S., first and second endings. ◆ ON STAGE A small marker low on the screen shows its state: Listening, Auto, Paused, Manual. Nothing else moves. Tapping the page edge always works, and so does a Bluetooth page-turner pedal, on every plan. A pedal is what you reach for when you stop trusting the software; charging for that would be indecent. ◆ ON THE STAND Apple Pencil markings with the full system tool palette, clear at any zoom. Keep them on layers — fingerings, bowings, your teacher's notes — and switch each on or off. A metronome with tap tempo, any time signature, 30–400 BPM, count-in and a tempo trainer. In silent mode it pulses the screen edge instead of clicking; it stops itself before a performance begins. In an ensemble, every device can lock to the same beat. A tuner beside it: how many cents off, which way to go, and a concert pitch you can move to 442 or 415. And a piano, voiced key by key from recorded concert grands, with a sustain pedal — check a note or chord without leaving the page. Default, Sepia and Night, for the rehearsal room, the pit and the 6am service, with adjustable warmth. Rehearsing together? Share your markings live with a nearby iPad — no router, no internet. On iPad, a rail down the edge scans the whole score: drag, watch the page ahead, let go. ◆ INVITE A FRIEND Share CueFlip with a friend. When they join, you earn points toward free Pro time. Find it in Settings. ◆ WHAT STAYS HERE No account, ever. Your scores, recordings and markings never leave this device unless you send them yourself or turn on iCloud Sync (your own iCloud only). Nothing from the microphone is uploaded unless you choose to send us a page-turn report. ◆ WHAT IT COSTS Automatic page turning is free. So are importing PDFs, learning from a recording, pedal and manual turns, and restoring a backup — with one score performable at a time. CueFlip Pro lifts that limit and adds iCloud sync, annotation layers, the metronome and ensemble sync, the tuner, the piano, folders, page editing, live annotation sharing, multi-movement scores, performance history, and export — a learned score someone else can perform straight away, or your whole library as one backup. CueFlip Lifetime is all of it, bought once, yours for good. A score beyond your plan is never deleted or locked — it just stops turning pages. Students and teachers: discounted Pro, details in-app. Subscriptions renew automatically through your Apple Account unless cancelled at least 24 hours before the period ends. Manage or cancel in Settings. --- ※ CueFlip contains no sheet music: bring the scores you already have. iPhone and iPad, iOS 16.4 or later. Even without automatic page turning, it is still a perfectly good score reader.

Verdict

The call

The clearest difference is rating: CueFlip at 5.0 against IMSLP's 4.6. CueFlip also leads on review sentiment (100% vs 70%). IMSLP's advantage is ratings volume (513 vs 1) and iOS requirement (13.0 vs 16.4). On price, update cadence, ads and in-app purchases there is nothing between them.
