I have played this app a few times, with varying degrees of success I'm ashamed to say! I think it could be a useful app for children who need to improve their working memory, attention and concentration. Ribbit frog Ribbit uses sound and visual cues, much like the old game Simon, but in a linear way.
First you press to show you are ready.
Then you listen to the notes, which increase or decrease in amount depending on how you are doing.
At some point when you repeat the sequence of notes, a coloured note pops out of one of the frogs' mouths, which you then have to identify at the end.
If you get the sequence wrong, the frog falls off the log. I'm not sure how long it would keep a child entertained, but I can see how regular short bursts could improve a child's working memory and attention skills. It's another one I will be trying in class.
