There's very little indication it's a subscription based service. I spent a lot of time writing up my first ad, then rewriting it repeatedly, as their filtering algorithm is a little overzealous. finally wrote one I was happy with, went to post the ad, and that's when it tells me about the different subscription payment options. I see it's buried near the end of the play store description, but I didn't see it on their website or FAQ or the app (until I hit submit ad). deceptive and time wasting
