Developer Julian Klode has released a new APK titled DNS66 for Android, allowing ads and some malicious sites to be blocked on your device.

Unfortunately the APK is not found on the Play store, however it can be found on F-Droid. Simply run the installer and install! Most unwanted domains are automatically filtered out. However it has the option for custom DNS servers a well.
