Reckon

Reckon is a decision journal designed for iPhone and iPad that helps users calibrate their judgment over time. Most decisions feel resolved the moment they are made, but Reckon preserves what hindsight typically erases: the original prediction, confidence level, and underlying reasoning. Through check-ins, users can track changes prior to an outcome by tagging new information as positive or negative and updating their confidence levels. At resolution, users log what actually happened, and weeks later the app prompts them to reflect on whether they would still make the same call. Over time, it reveals where confidence overshoots or undershoots and where judgment is sharpest.
