KALHI Markets Discoverer is a journal for the numbers you put on your own guesses. You already forecast constantly — whether the delivery arrives Friday, whether the deal closes, whether the queue is worth joining. You just never write the percentage down, so you never learn whether your confidence means anything.
This app fixes that: file the claim with a date and a number, judge it when the date lands, and the curve tells you where you flatter yourself.
Fully offline: no account, no sync, no server, no subscription.
Uncomfortable by design — most people find they are running six to fifteen points overconfident, and the only way to see it is to write the number down first.

The camera and photo library are only accessed when you choose to attach source evidence to a call. Those images never leave your device.
No tracking, no advertising
There are no advertising SDKs, no third-party analytics and no tracking of any kind. The app does not access your location, your contacts or your microphone. There are no purchases, no subscriptions and no advertising.

KALHI Markets Discoverer is a tool for personal thinking and record-keeping. Its scores reflect your past accuracy only. They are not advice, prediction or recommendation of any kind, including financial advice.
Warm-up questions
The warm-up questions are bundled general-knowledge probes only, used to establish a starting mark against which your later calls can be measured.
