This is really for use in the classroom but if you have a fairly new Mobile Phone you may be able to use as well, you might have to pinch zoom out to make it work. It is worth a go.
All you do is press the green button and let your students try to put the phonetic sounds together to make the CVC word. I have made it so it SHOULD just be CVC words, and no long vowel sounds should appear. ( soft C sometimes does but i couldn’t stop that!)
