Cheep and does not sync
It requires an email for the paid verson. The default setting is set to Share and can not be changed to default to Private (even though the paid version is titled "Private"). It will not allow you to use the same user name on your other device. I.e you cant sign in on your iPhone if the user name is on your iPad. This is an app that has potential but the designers seem to be more interested in people chatting about their troubles and make it hard to maintain privicy. It is the cheapest functioning app Ive run into. It was a deceptive way to get my money.
