P-Chord Piano Chord is a free Android app developed by Asoft under the multimedia category, specifically for music and radio. This app functions as a chord book for the piano and displays the form in the right hand. With the current version, all chords are available for free in the app, but if you choose to remove the ads by charging, the display will be slightly larger. It's worth noting that this app does not support Android 11 or higher, and the timing for an upgrade is currently undecided due to a lack of staff. However, there may be additional chords added in future versions.

Overall, P-Chord Piano Chord is a useful app for piano players looking for a comprehensive chord book, and the ability to remove ads is a nice bonus. However, the lack of support for Android 11 or higher may be a drawback for some users.
