Can't find app support – Ad-Free Unit Converter Review

Hi, I like the idea for a converter but this one won't let me enter values. What am I doing wrong? Tried to enter 5lb 6oz to get the equivalent in grams but it will only tell me that 1lb equals 1.536grams. So I need to exit the app and do the math. Where's the convenience in that?
