# Keep Uncertain Onset Dates as Ranges Instead of Guessing an Order — Free

A remembered onset “between Tuesday and Thursday” is a range, not a date to invent. Preserve that uncertainty and show which pairs cannot support a claimed order or minimum day gap.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

People organizing uncertain dates before a clinical conversation

## What's free

- one full, unwatermarked uncertain-onset docket App execution
- three invented readings and unlimited calculations in the paired article demo
- copy the complete working and boundary; voluntarily share non-sensitive input state

## Optional paid add-on

**$4 one-time.**

- subsequent uncertain-onset docket App calculations through a browser-local convenience signal
- boundary-preserving print and row-and-summary CSV of this uncertain-onset docket; conditional retyping budget uses only your entered minutes
- five local headline/count/time summaries, separately deletable; full-input draft is separate and not a backup
