Good morning. 

I like the app, also in Italian is well done and intuitive to understand and to program. It’s full of interesting info and give plenty of advice. You need to modify few words that have probably been translated thru a web based translator. The days of the week are:

Monday = Lunedí

Tuesday = Martedí

Wednesday = Mercoledí

Thursday = Giovedí

Friday = Venerdí

Saturday = Sabato

Sinday = Domenica
