Best Android app for random and anonymous chatting I think would be

Dating Single Strangers | Anonymous Chat | Say Hi5 - Apps on Google Play, random chat

It has all features of tinder where you swipe left and right and match with strangers also it has features like group chat and also anonymous chat where you dont need login and you can chat anonymously in chat groups..

It has all checks where you can check the preferences smoker, non smoker drinking everything is menioned and you can get your perfect partner< it has a good user base and currently i think i am loving this app

it has best of everything and best part is its absolutely FREE. No charges or subscription

It is better than omegle or chatiw
