Keep WiFi for Android will make your life easier by forcing your Android phone not to turn your WiFi off during sleep. If you have an unlimited data plan you will not bother, but otherwise it could save you money. This service does not influence your normal WiFi enable/disable behavior. If you switch your WiFi off by yourself, KeepWiFi service will not block it. This service will keep your Wifi connection on air, even if your phone's screen goes off.
