I use a lot of technology with my speech and language kiddos! I have an iPad that I use almost daily. Here are a few that you may also find helpful:
Articulation:
Articulation Station: you can buy only the sounds your child has to work on instead of purchasing the whole app.
there is an app called Chatterbox that I think is free. It may only be free for one set of flashcards but you can use it to practice your child's speech sounds at home.
Language:
Sentence Builder
Preposition Builder
Toca House
My Play Home
My Town
Vocabulary:
Peek a boo Barn
Peek a boo Fridge
Apraxia:
Word Flips from Super Duper Publications-this is my favorite app for the kids who have difficulty sequencing syllables.
Other:
Pogg: this app is a favorite for my kids. It’s this alien who does different actions and they usually involve him falling down or hurting himself somehow. I use it to get kids talking when they are shy or nervous and I use it to get kids describing what he is doing. (He is swimming; he is swinging, etc).
