Our take

Start with local composition, then check which cloud functions your plan includes.

Multiple input methods and common music formats support both quick sketches and arranged scores.

Keep in mind: The desktop listing places cloud sync and collaboration in Power, while the website describes a free 15-score cloud tier. Verify desktop entitlement rather than assuming identical plans. PDF recognition uses credits.

What you can do

  • Keyboard, fretboard and MIDI note input
  • MusicXML/MIDI and PDF import
  • Sheet music and audio export

Review themes: 4 US App Store written reviews, updated Jun 30, 2026–Aug 15, 2026. Collected Nov 6, 2026.

Review sources & grouping details

These themes use the completed local review collection and Codex analysis: the latest accessible written reviews within one year, up to 500 per app. This is an accessible sample, not a guarantee of all reviews or a measure of all users.

The feed does not identify each review’s platform. Its date is an update timestamp and may reflect an edited review. Versions shown belong to individual reviews; reported limitations are not verified current-version behavior.

Codex grouped explicit opinions from the review text, with original-text evidence retained. Counts use distinct review IDs, independently of star rating. A review may appear in several topics. The three most-mentioned topics per side are shown first; where more are available, expand the list to see every topic supported by at least three reviews. Group summaries describe recurring aspects across the group; individual examples retain their own context and do not stand in for the whole group. 0 reviews were too general, unclear or off-topic to assign a specific theme. Example summaries are paraphrases; the labeled excerpts are original review text. Analysis updated Nov 15, 2026.
