There has been a degree of confusion about Google App Inventor (on my part) – not least because it didn’t originally have a name and there was a second ‘full blown’ software development kit (SDK) available from Google.
The full Android SDK is extremely comprehensive and comes with emulators for a wide range of phones enabling very sophisticated apps to be developed ….. HOWEVER …. it is tha App Inventor that appeals to me.
The ‘SCRATCH’ like interface seems the perfect next step for KS3 pupils.
