Love the Sicilian language and culture, hence why I downloaded this app and took a risk in paying the $29.99 although the interface is nice and the app doesn't seem to have any bugs it is really really under developed. There are basically no phrases even when you pay for the premium version, no guided lessons with audio, no videos etc I wouldn't recommend paying for this app just yet or at least not premium until it has over 500 common phrases and over 1000 common words.

Hi Zeljko, sorry to hear you feel this way. There's currently over 250 phrases, over 500 words and over 300 conjugations of verbs past and present available in 9 different Sicilian dialects, translated into 3 languages.. Lessons are a new feature recently added which will improve. User subscriptions help fund development to improve the app.
