Record rainfall from your own rain gauge, compare years at a glance, and keep your history backed up and synced across iPhone, iPad and Android. RainLog is built for rain gauge owners, farmers, gardeners, weather enthusiasts and property managers who want reliable records based on their own measurements—not generic online weather data. FAST, FLEXIBLE RECORDING • Record rain or snow in millimetres or inches • Add trace amounts, weather icons and notes • Record garden, crop and property watering • Manage multiple rain gauges in one place POWERFUL GRAPHS AND COMPARISONS See monthly and yearly totals, Month-to-Date and Year-to-Date comparisons, four-year totals, rolling 12-month rainfall and long-term 2-, 5- and 10-year averages. Choose a custom rainfall year—such as July to June—to match your seasons, farm records or local climate. SHARED RAIN GAUGES Share a gauge with another RainLog user. Give trusted family members, workers or property managers view-only access, or allow them to add and edit rainfall readings for that gauge. The gauge remains under the owner’s account, and invited users do not need their own subscription to access a gauge shared with them. SYNC ACROSS DEVICES Sign in with your RainLog account to securely synchronise rainfall records across supported Apple and Android devices. BACKUPS AND CSV EXPORT Protect your rainfall history with backup tools and automatic CSV backups. Export records in date order for use with Excel, Numbers or farm record systems—your data remains useful outside RainLog. COMMUNITY RAIN MAP Optionally share rainfall summaries from selected gauges and view rainfall reported by other RainLog users on an interactive map. BUILT FOR REAL RAINFALL RECORDS RainLog is designed for people who read their own rain gauge or weather station. It does not automatically substitute online weather estimates for your measurements, helping you maintain a personal and consistent rainfall history. Your rainfall. Your gauge. Your history. RainLog includes a limited free trial so you can explore the app before subscribing. Annual subscription plans are based on the number of gauges you manage and support the continued development and maintenance of RainLog.
