Insider internet dating forum
Tinder is a free dating app for smartphones that gets mixed reviews: positive from users who seem to be seeking short-term encounters and negative from users who bemoan the superficiality of a match system that's all about physical appearance.
The upgrade means showing up at or just shy of the top in searches, seeing a user's extended profile, seeing if your messages were read, and being able to use themes (e.g., designs and colors) to make your profile stand out -- features that seem more like frills than necessities.
OK Cupid also maintains a well-reviewed mobile app that has been downloaded from the Google Play Store more than one million times.
It earns four out of five stars and is the target of some griping about minor glitches. A monthly fee of .95 for six months, .95 for three months, or .95 for one month earn you a spot on the "A-List." The benefits, however, seem dubious: the ability to browse profiles invisibly; search through matches based on appearance, body type, or personality; see when someone has read your message; change your username; and kill ads.
Plenty of Fish has a strong mobile app and has been downloaded more than 10 million times from the Google Play Store, where it garners an average 4.5 stars in reviews.
A few users report minor operational problems but otherwise offer praise for its clean structure and ease of use.Plenty of Fish is one of the oldest dating sites and boasts a moderate-sized user base.
