App driving me crazy

Kiera • Married April 18th. Trying for second baby :)
I am 35 weeks and trying to find a breastfeeding app for when I start breastfeeding. I downloaded smallnest and it won't let me input any data and its pissing me off because it has great reviews and I haven't found any other app I like so far. Does anyone know how to solve this problem? I already emailed the company yesterday. If not than does anyone use an app they could suggest
