The app was advertised as being FREE today instead of $1.99. The promo says, “NOW INCLUDES OVER 20+ TOP NURSERY RHYMES OF ALL TIME”  but the reality is that the download only has one free song – Mary Had a Little Lamb. You can also get 2 bonus songs – if you go to their Facebook page. If you click on any other songs, it wants you to upload to the pro version. That’s where you get the 20+ nursery rhymes. In Song Mode, you can play & listen to a song or you can play the song by following the highlighted keys. You can also record the song as you play it then play it back. The FREE version does allow you to exit song mode and play the xylophone on your own. Just like in Song Mode, you can record as you play then replay it. The app is nicely designed and has a good tone to it. You may want to try it while it’s FREE.
