A data collection app for iPhones and iPads created for ranches with multiple rain gauges or wells positioned around the property. The user can choose to view gauge or well locations on maps as a group or individually. With the individual presentation there is also the facility to specify a date range and display rainfall recorded for that period, or changes in depth to water. The data entry option presents a list of gauges or wells in ascending alphabetic order and new gauges or wells may be added, gauge and well data include name, latitude, longitude and elevation and well depth. Upon selection of a gauge or well the user then enters the rainfall noted for that gauge, or depth to water for that well, which is then presented in the order of most recent observation to earlier observations. There is the facility in both gauge or well entry and rainfall or water depth entry to edit existing entries, this facility is useful to add historic data. Should the user wish to export data from this app, the iTunes File Sharing mode may be used to export SQLite files which may then be imported into an SQLite file reader or manipulator on the users computer. Gauge and well names and locations may be pre-loaded on a one time basis via iTunes File Sharing with JSON files.
