Offline decision journal

Know if your judgement is any good

Calibration

Stated confidence vs what actually happened

Perfectly calibrated You — dot size = sample

When you say ~70% sure, you are right about 62% of the time.

The method

Four steps, then the truth

A decision journal is an old idea that fails on paper for one reason: nothing brings you back to check. Forecall fixes exactly that.

01

Record the call

The situation, the options you weighed, the one you chose — and why. Written now, not reconstructed later.

02

Commit a prediction

State what you expect to be true, and how sure you are. The number is what makes it scoreable.

03

Get called back

On its review date the decision reappears in Today. Compare, then mark it right, partly right or wrong.

04

See your calibration

Watch whether your 70% really means 70%. Most people learn they are overconfident — that is the useful part.

What's inside

A full journal, not a notes app

Everything computes on your device — the statistics, the streaks, the exports.

The calibration curve

Your stated confidence plotted against your real hit rate, with the gap shaded. Dot size shows how much data each band rests on, so a single decision never looks like a verdict.

Today & Upcoming agenda

Overdue, due today, next seven days. The app pulls you back when a decision is ripe for scoring — no notifications, no permissions.

Brier & bias scores

A single number for accuracy, and a signed figure telling you if you run over- or under-confident.

Streaks & achievements

A logging streak, a review-on-time streak, and eight badges — including one for writing lessons after a call goes wrong.

Search & filters

Full-text search across every field, plus filters for category, outcome, stakes and confidence band.

Export & backup

Full-fidelity JSON you can restore, plus a CSV that opens in any spreadsheet. Your journal is yours to take.

Goals you set

Log three a week, keep reviews 80% on time, hold calibration error under ten points — measured live.

Options, not just outcomes

Record every alternative you considered and why you set it aside. The road not taken is half the lesson.

Encrypted on device

Your journal sits in an AES-encrypted local store whose key never leaves the phone's keystore.

Archive, trash and undo

Every destructive action offers an undo, archived decisions stay out of the way, and deleted ones wait 30 days in the trash before they go for good.

Made yours

Light, dark or automatic; six accents; three densities. An editorial type system built for reading, not for dashboards.

Privacy

Your decisions are nobody else's business

A decision journal only works if you are honest in it. That is impossible if it is being uploaded somewhere — so Forecall does not upload anything, ever.
