This is a small app which makes it very easy to look up values in tables (math etc) when you have to interpolate both in two and in three rows. No more need for a calculator to interpolate manually. This app was designed primarily for cargo surveyors working with tank calibration tables, but the app does have its application in any environment where tables are used. As of 13th January 2015, this app has become FREE until further notice.
