From Gaston Santiago:
ThreePointEst is a utility app that calculates the PERT-based three point estimation technique, which allows for a more accurate estimation than just by single point methods of estimation. Use this app to estimate time, duration, cost, or practically anything that needs estimation.FEATURES:* Use a slider to control the decimal precision (up to 10 digits)* Easily toggle between positive and negative input values.* Computes the standard deviation (SD) in addition to the three point estimate.* Numeric-only input keyboard minimizes user input errors.
