"Poco-a-Poco: Music Reading Essentials" helps learning and practicing sheet music reading, understanding musical signs and symbols, note names, rhythms, intervals and more. Designed with the help of professional piano teachers, this fundamental tool is for those who are learning to play piano or other musical instruments, as well as for anybody who needs practicing sheet music reading. The application has four sets of flash cards divided into stages with increasing knowledge level. By choosing either one or a combination of any of the four sets, you can start testing yourself and study at the same time. The specially designed shuffling algorithm will start showing more often those cards, which were not answered correctly. Choose Notes from either Treble clef, Bass clef, Alto clef or the combination of Treble and Bass clefs ("Grand" mode). Use "Timer" to test your knowledge. The "Results" screen will show your progress as well what you need to continue working on. With the "Cards Info" screen you can see how the cards are arranged by sets and stages.

Verdict
The clearest difference is price: K at Free against Music Reading Essentials's $2.99. K also leads on update cadence (every 3 days vs every 20 months) and rating (5.0 vs 4.6). Music Reading Essentials's advantage is ratings volume (11 vs 1) and iOS requirement (15.0 vs 17.0). On ads, in-app purchases and monetization model there is nothing between them.
