This application collects georeferenced field data in a Sqlite database. Data is entered by selecting attributes from three dropdown boxes, (Species, Location, and Sampler) that are user editable, then initiating a count event to create a record. An additional comments field is also available to store up to 512 characters to further describe that record.
Counts are made by pressing graphical buttons on the display with defined values for fast data entry. An additional 10-key popup keypad is available for more precise counts if time permits. Total cumulative counts for the subset of dropdown fields selected are shown in the "Total Number Counted" field. An additional tracklog feature is available that records latitude, longitude, satellite time, device time, and altitude at user defined intervals.
Collected data may be reviewed on the Data Table tab. Individual records selected on this tab are loaded into the Data Edit tab where values may be updated as needed.
The GPS Data tab shows current latitude, longitude, satellite time, satellites in view, satellites in use, as well as altitude, signal accuracy, and speed with all three in both metric and English units.

This application was originally written to collect biological field data in rapidly changing situations, such as flying in small aircraft at low altitudes counting wildlife, or counting fish in shallow rivers from a boat or in waders. Previous versions of this software primarily ran on PDA devices that used the Windows CE operating system. Until recently, hardware buttons were a primary method of program control on mobile devices with a standard configuration of 4 buttons plus a small toggle button in the middle, (Dell Axim, Juniper Archer, Palm Pilot, etc). This allowed the user to make counts while observing without having look at the device. This is important when observing from aircraft or counting animals as they move past (such as fish in a river, or birds overhead). The current generation of Gorilla Glass tablets and phones without exception lack hardware buttons in a standardized configuration. Further development in this application will seek to resolve this problem in an intuitive manner.
