Reckon
Decision journal that scores your 70%-sure calls against what actually happened
Reckon is an iPhone/iPad app for logging predictions — what you expect, how sure you are, 0–100% — then marking the outcome later, so your stated confidence can't be rewritten by hindsight. After 15 resolved calls (3+ per domain for a per-domain breakdown) it plots a calibration chart showing whether your 70%-sure calls actually come true about 70% of the time. It's a one-time $3.99 purchase with iCloud sync, no subscription, and the maker lists upfront what it doesn't do.
What holds up
- +One-time $3.99 — no subscription to cancel later
- +Predictions and confidence levels lock once logged — hindsight can't quietly rewrite them
- +Syncs over iCloud with no account needed beyond your Apple ID
Mind the limits
- −Needs 15 resolved calls (3+ per domain) before calibration charts become meaningful — no instant payoff
- −iPhone/iPad only — no Android or web version
