It's great!...until it starts to essentially harass you. If I don't text for two weeks it starts threatening to have my number revoked; like that'll somehow force me to use the app more. Then I suppose I texted "too much" and it wouldn't let me talk to my friend for a whole entire day. I understand it's a free texting app, it won't be perfect, but I should be able to decide if I do or don't want to text. What's worse? They don't even always follow through, just threats for no reason.
