Decisioneer

Weighted Decision Analysis

Free · Designed for iPad. Not verified for macOS.

Now optimised for iPhone Duo and runs natively on Mac. Decisioneer helps you make clearer decisions when the trade-offs are too complex for a simple pros-and-cons list. Compare options against weighted criteria, score each candidate consistently, and see which choice rises to the top. Decisioneer is useful for comparing products, suppliers, homes, projects, investments, locations, purchases, or any decision where several factors matter at once. Add candidates, define criteria, set weights, enter scores, and review a ranked result with the reasoning behind it. You can also add requirements, calculations, notes, source links, images, and reusable decision templates. Decisioneer supports: Weighted decision matrices Candidate comparison and ranking Rating, yes/no, numeric, date, duration, and location criteria Requirement filters for must-have conditions Calculated criteria such as currency conversion and payback period Visual weighting tools Score breakdowns and recommendation drivers Monte Carlo simulations Local decision files and exportable reports Your decisions stay under your control. Decisioneer stores your work locally on your device, does not require an account, and does not include advertising or analytics tracking.
