Dyseggia is an aplication that trains phonological awareness through games (tasks like add, remove, sustitute letters into a word, separate words etc.).
Secondarily it helps to train orthography (in some activities, player has to change one letter or add one in order to write it correctly).This app is free and there is also a spanish version of it “Piruletras”. Available on apple store.
Our kids with learning disabilities enjoy this app more than traditional pen and pencil activities, though we might be aware that this is a complementary tool.
¡Hopping it will be usefull for you!
