### 4/5 — Fantastic when it works

*2026-03-26, version 2.0*

I don’t even attempt to use this when other instruments are involved as it seems to become confused. Most of the time it’s great but occasionally it doesn’t turn the page and if you have to turn manually it stops turning entirely. So 4 stars for working most of the time.

### 1/5 — KeyScore Has Gone Downhill

*2026-03-12, version 2.0*

It has reached the point that the program is not useable.  I put together a set list and save it.  Then I go to open that set list and the app closes completely.  The app is not useable anymore.  This has been going on for many months.  The error self generates error codes I have forwarded to the developer and also written notes.  I must have forwarded 50 to 100 error codes and the developer doesn’t reply.  I am past frustrating and upset that I have wasted the time and energy the past 4 years putting my music in to this app.

### 5/5 — Thank you

*2026-03-07, version 2.0*

This is a great app for reading and importing music. Excellent features. Very happy to pay for this app.

### 4/5 — Excellent scanner

*2026-03-05, version 2.0*

The ability to dynamicaly correct scanned images and straighten the staves before creating a pdf is superb.
This combined with easy transfer to other apps or storage makes this my go to sheet music scanner.
The apps ability though to auto turn pages is not reliable enough.
It would be a big improvement if a midi control of page turning was built in which allowed any midi signal to be a page turning event.

### 5/5 — Love it!

*2026-02-22, version 2.0*

I am not a professional musician. I play in the local community orchestra as well as a summer wind ensemble. I was tired of constantly losing pages or not being able to write on music that needed to be returned/ chasing music during windy outdoor performances. Key Score fits my needs perfectly. I love the half page turn option, so I don’t miss a single measure!  Marking up music is easy. You can even make a playlist so there’s no searching around during a concert for your next piece. I have not had great success using the tracking feature or automatic page turn, but for what I need the app for it’s great!

### 1/5 — Recover Deleted Scores

*2026-01-27, version 2.0*

Hi, is there a way to recover deleted scores?

### 1/5 — Developers have dropped support!

*2025-12-19, version 2.0*

They have let it go.  No responses to emails, no updates.  Program used to be great now is a big hassle.  Until developers start responding, leave the app alone!

### 3/5 — Disappointing V2

*2025-12-11, version 2.0*

When I discovered Keyscore a couple of years back, it was a godsent gift. Being a church organist, I no longer had to carry loads of large music scores. I have over 250 scores in Keyscore. Keyscore worked most of the time. Then V2 arrived, with its jumping staves, it’s delayed repeats, it’s lower sensitivity to soft organ sounds and it’s unpredictability. E-mailed the developers twice, with no response. I use it mainly for one page scores nowadays.

### 5/5 — Einzigartig

*2025-11-14, version 2.0*

Um beim Notenumblättern zu helfen, scannt die App die Papiernoten mit den eigenen Markierungen druckfertig abgeglichen  und mit fast besserem Kontrast als im Original. Es bearbeitet dann die Noten so, dass das pad-Mikro exakt den Spielverlauf registriert, also nicht angewiesen ist auf metronomartiges Abzählen von Takten, vielmehr geduldig wartet, falls  ein korrekturversuch gespielt wird. Da capo-Rückblenden efolgen natürlich automatisch, es ist - sehr erleichternd für den Laien - keinerlei Reaktion des spielers beim Seitenwechsel erforderlich. Kleiner Nebeneffekt: weil das Micro ohnehin in Aktion ist , kann jedes gespielte Stück (zu Trainingszwecken) gespeichert werden.
Als Laien-pianist bin ich von der überragenden Qualität dieser genialen App überrascht und empfinde sie dankbar als große Hilfe.

### 1/5 — Great concept, Terrible execution

*2025-10-31, version 2.0*

I gave a piano recital 3 years ago using the app and it worked great.  The Timberlabs guy was so helpful.  Today, I can only upload one page at a time and there is no customer service…no replies to email. What was loaded previously works but cannot get anything new uploaded.  Shame really.
