Great app

"I am so happy that I downloaded this app and I am a paid user. I downloaded because I have one of those robot lawnmower. I don't want it to go out after the rain so I keep an eye on the rain in the past with this app. Now with the new forecast feature I can plan when to send the lawnmower out and for how long. Lawnmower has it's own rain sensor but once the rain stops it starts back up. I don't want it to go back so I don't program it to mow it it rained."
