I am going to start with the cons for Sweatt, the number on our list of best free dating sites for singles in NYC because there is just one, which is the app for Sweatt is not available for Android devices as of now. However, the website claims that they are working on an Android version, and soon everyone will have access to Sweatt. For the time being, if you own an Android device, Sweatt can be an excellent app for you. This app is basically for the gym-going community, which is huge in New York City. This app is also exclusive to New York City as well. If you are on a quest to keep fit and would love it if your partner were also into the trend, then this is the only dating app out there that can ensure your mutual love for workouts and keeping fit.
