Reckon
The decision journal that helps you calibrate
Most decisions feel resolved the moment you make them. Reckon keeps what hindsight erases: the prediction, the confidence, the reasoning. Check-ins capture what changes before the outcome: new info tagged positive or negative, confidence updated. At resolution you log what happened; weeks later it asks if you'd still make the call. A year in, you see where confidence overshoots, where it undershoots, where judgment is sharpest. iPhone and iPad. iCloud sync, no account. One-time purchase.
I built this because I noticed the same thing keeps happening to me: I make a call, the outcome arrives a few weeks later, and by the time I remember what I had predicted, the story has already been re-written by hindsight. The version of me that hesitated, that wasn't sure, is gone, and with it anything I could have learned.
A note app captures what happened. A journal captures how I felt. Neither captures what I predicted, or how confident I was before I knew. So I built the thing that does.
Reckon is a decision journal where the moment of choice is the beginning, not the end. You log a prediction with a confidence percentage and a review date. Between then and resolution, check-ins capture what changed: new information tagged positive or negative, updated confidence. At resolution, you log the outcome and how satisfied you are. 30 to 60 days later, the app asks again: would you make this call again? Because satisfaction doesn't always align with "would I do it again".
After enough decisions, calibration becomes something you can see: where your confidence overshoots outcomes, where it undershoots, which domains your judgment is sharp in.
It's for anyone who has ever felt their judgment is good but couldn't prove it, or the contrary, doesn't have confidence in theirs and needs a history. Founders, parents, planners, investors, people who care about thinking clearly. Not pitched at the forecasting community, but legible to them.
I would love your honest feedback! I'm especially curious if "calibration" makes sense for non-forecasters, or does the framing need to improve?
