There is no totally free dating app. The only app I used which is totally free is the Lemon app. This app has very limited functionality, and it does the purpose of dating. But it's not good for serious dating.   Other dating apps are not completely free, but provide most of the features for free. These apps are:   1. Lemon 2. Sweet Chat 3. Tantan 4. Tinder 5. OkCupid
