User reviews

The ads are getting longer

I have been using this app for years and I really enjoyed using it. But the ads are getting longer and longer and it bothers me so much that eventually makes me not want to use this app anymore…some ads I need to wait more than 40 seconds which is ridiculous. I understand that you need to put ads in the app but please make it shorter

Confused

Id love to love this app but for some reason at the intro its not letting me put my birthday or
my anniversary with my boyfriend?? I don’t know how to fix it please help

Cookies

Says it wants to give personalized ads and to click allow in order to process it. It has an option to ask the app not to track but it doesn’t work, you literally have to let the app track you to proceed. Screw that.

광고가 너무 많이 나와요

대답 할때마다 광고가 나오는곤 조금 그런것 같아요.. 예전에는 한번 구매였는데 이제는 매달 돈내야하고..
