My Rainfall allows you to enter your own rainfall data under individual gauge names. You can enter multiple gauges. This data can then be viewed on a bar graph or line graph, by month and by year. You can also view the average rainfall for your selected location for the past 100 years. You can then compare your rainfall data to the district average by month and by year. Your rainfall data is fully editable. You can also download your rainfall data to an Excel file on your device, which shows data for the current and past years (depending on what years you entered data for). Past rainfall can be added as a monthly total to save time. There is no option to import past data from Excel, csv etc files.
