Reckon

Reckon is a decision journal for iPhone and iPad that records your predictions, confidence, and reasoning, then shows how your judgment holds up. Log calls when outcomes are uncertain, add quick check-ins as information changes, and later mark what happened and how satisfied you were. Over many decisions, Reckon plots predicted versus observed results and highlights over- or under-confidence across domains. It syncs via iCloud, requires no account, and is a one-time purchase.
