After my yard died last year, I was determined to water my lawn this year. I have a rain gauge that tells me if it has rained enough to forgo watering, but does not tell me the rain by week. Your yard needs around "1.5 inches of water a week to stay healthy. This app helps me log the rain by day. I would really like it if on the week report it could give me the total by week. Small effort change, but a big help! That would be worth another star. As for those who thought this app would somehow know how much it rained at Their house....... Interesting.
