The short version
Piascore is a free PDF sheet-music reader for iPad and iPhone, in the same category as forScore. It displays the page; it does not read the notation from a photograph into playable notes and has no AI coach. Sheetly photographs your own printed page, turns it into a score that plays, and lets you ask a coach about that score by bar number. If you want a free place to keep and read PDFs, keep Piascore. If you want the page to play, try Sheetly.
- Keep Piascore if what you need is a free PDF reader for music on an iPad or iPhone. Sheetly does not replace a reader.
- Try Sheetly if you want a printed page or a PDF to play: at any tempo, looped on the hard bars, with a coach that has read the notes.
- Sheetly is, as far as we know, the only sheet-music app where you photograph your own printed page and then ask an AI coach questions about that score by bar number. It does not listen to you play and it does not replace a teacher.
We make Sheetly. We have not measured Piascore and make no claims about it beyond what its own materials describe. Where Piascore is the better tool we say so.
“Piascore alternative” is usually typed by someone who has just realised that a reader reads the file, not the music. That is not a complaint about Piascore. Hearing the notes is a different job, and it needs an app that understands the notation rather than the pixels.
What Piascore is for
Piascore is a free PDF sheet-music reader for iPad and iPhone, per its own materials, in the same category as forScore: a place to keep PDF scores and read them on a tablet. It treats the page as an image. It does not read the notation from a photograph into playable notes, and it has no coach that has read your specific page.
For a lot of musicians that is exactly enough. Someone who sight-reads well, or who is accompanying and only needs the part in front of them, gains nothing from the app interpreting the notes. A free reader on an iPad is a good answer for that person, and nothing here argues with it.
The gap is the learner’s gap. A learner wants to know what bar 9 sounds like before attempting it, wants bars 9–12 looped at half speed, and wants to ask what the fingering should be. A reader cannot do any of that, because to a reader the notes are shapes on a page, not pitches with durations.
Piascore and Sheetly side by side
Piascore is a free PDF reader with no notation recognition and no coach; Sheetly reads a photographed or imported page into playable notes, plays it, loops it, records your take and includes a coach that has read the score. Neither app listens to you play. Piascore is free; Sheetly is free to download with a Pro subscription.

What Sheetly does with your page
Sheetly photographs a printed page or imports a PDF, reads the engraved notation on a server, and returns a score that plays. Set any tempo, loop a bar or passage, choose piano, organ, flute, trumpet or another sound, record your own take against the score, and export PDF, MIDI or MusicXML. The coach has read the actual notes of the scanned piece and answers by bar number.
Reading accuracy is measured rather than claimed. On Sheetly’s own 31-piece benchmark the strict F1 (pitch, onset and duration all correct) was 96% on clean renders and 95% on simulated phone photographs. On OLiMPiC, a public suite of 60 systems cut from real scanned pages we did not author, it scored 90% mean and 99% median, with usable output for all 60. Method on the benchmark page; closed products were not measured.
Ask Sheetly: a coach that has read your score
Not a chatbot bolted onto a music app. The coach has the actual notes of the page you just photographed, so you can ask about your bar 12 and get an answer about what is written in it.
The coach has read the notes on the page. A reader shows the same page and cannot say any of this.
And what it does not do
Sheetly does not listen to you play through the microphone and does not mark your notes right or wrong. It reads printed, engraved notation only: not handwriting, not guitar tab, not shape notes. There is no correction editor; a misread note means a better photograph and a rescan. It needs a connection to scan and to ask the coach; scanned scores play back offline.
Which one should you use?
Keep Piascore if you want a free PDF reader for music on an iPad or iPhone and you do not need the page to make a sound. Use Sheetly if you are learning from a printed page or a PDF and want to hear it, loop the hard bars, record a take and ask a coach what is written there. Both can sit on the same iPad.
- You need a free place to keep and read PDFs. Piascore.
- You perform from a tablet and read fluently. Piascore, or forScore.
- You are learning a piece and want to hear it. Sheetly.
- You want to ask about bar 10 of this page. Sheetly.
- You want the app to hear you play. Neither; look at a lesson app.
Same page. Now it plays.
Photograph the printed page or import the PDF, hear it within a minute, loop the bars that need work, and ask the coach what to drill. Free to download on iPhone and iPad.

Questions
Can Sheetly replace Piascore?
For reading and keeping a library of PDFs, no. Piascore is a free PDF reader and Sheetly does not try to be one. Sheetly replaces Piascore only for the learner who wanted the page to play, loop and be explained by a coach rather than simply displayed.
Does Piascore play the notes on the page?
Not as far as its own materials describe. Piascore displays PDF sheet music on an iPad or iPhone; it does not read the notation into playable notes. Sheetly reads a photographed or imported page into a score that plays at any tempo.
Can Sheetly import the PDFs I already have in Piascore?
Yes, if they are printed, engraved notation. Sheetly imports a PDF, reads the notes on a server and plays the result; it does not read handwriting, guitar tab or shape notes, and it has no correction editor. Sheetly exports PDF, MIDI and MusicXML.
Is Sheetly free like Piascore?
Sheetly is free to download on iPhone and iPad, with a Pro subscription for the features a learner uses daily. Sheetly needs a connection to scan a page and to ask the coach; scores already scanned play back offline.
