TestStripDecoder app for iPhone and iPad

This app automates the reduction of test data from color change tests.Snap an image of a test strip and color key map, use text recognition to map colors to values, and read the test strip to interpolate the reading. The result can be copied to the clip board or saved in a comma separated spreadsheet file. The built in timer can be used to time tests and is annotated to the stored record. Manual entry of key values is supported. A practice file is provided to familiarize the user with the app controls. The most important factor in obtaining accurate results is even lighting across the test strip and color keys.
