Breastfeeding apps?

Jacqueline
Hey y'all I just had my beautiful baby girl on the 10th & she is absolutely prefect! Breastfeeding is going great :) but I wanted to know if there is any apps out there that people are head over heels about & that every breastfeeding mom should have. Please let me know if you have an app or have heard of one that everyone is ranting & raving about & if you know the price of if, if not no but deal I'll just look it up :) thank you!!!
