For a long time I faced questions from teachers about using Scratch on the iPad. They had used it successfully on PC, laptop or Mac, but when it came to tablets, they settled for web based alternatives, or even tried Scratch Jr. While Scratch Jr is great for younger children and a super starting block, it has limited features and lacks some of the coding elements that Key Stage 2 require.
Now Pyonkee solves this problem. A free app available on iOS, meaning anyone with an iPad can get it, with almost all of the features of Scratch on a PC. The only thing lacking is the ability to save projects to a shared file, but you can email them to yourself or your teacher. You may also see the missing cat and different logo, but other than that, it is essentially Scratch.
When using this app with children, I have found that they manage really well, however changing numerical values is slightly tricky as they require nimble fingers.
A latest release will hopefully mean it is slightly more stable, as occasionally it did crash on iPads that had very little memory.
I think the app is a very useful resource to get children programming on tablets where no PC is available, and the free price tag is even more appealing.
