Inspect Three Same-Session Thermometer Readings Without Diagnosing Them

Repeated readings can disagree even when a thermometer appears consistent. Keep a small same-session set visible, including its smallest and largest values, before asking whether your measurement technique or device needs checking.

FIRST-LOAD

HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.

Data note: The replicate-range dial processes Session code | first °C | second °C | third °C locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.

Perspective: Before: three readings became one guessed correct temperature. After: their mean and spread remain separate observations for a technique discussion.

2 · Read the replicate-range dial

Measurement summary only, not diagnosis or treatment advice. Follow your thermometer's instructions and ask a pharmacist or qualified clinician about inconsistent readings; seek appropriate care for concerning symptoms rather than relying on this spread check.

Paid layer: replicate-range dial filing layer

one-time step · the free reading above stays complete

hidden patterns detected after your first run

Free tier

one complete unwatermarked replicate-range dial run in the app
three labeled samples and unlimited article-demo calculations
complete result text and a user-triggered input-state link

What $4 one-time adds

unlimited subsequent replicate-range dial app calculations after a local convenience signal
print the replicate-range dial with visible assumptions and its safety boundary
CSV of the displayed °C range and row workings; conditional estimate uses your manual-retyping minutes
five local reading summaries (headline/count/time), not saved full inputs or cross-device backups

HYPOTHESIS / PROTOTYPE: $4 is a proposed one-time price for filing the replicate-range dial, not a current sales offer. No measured time saving or buyer demand is claimed. The optional manual-retyping baseline above estimates one export’s retyping budget only; it does not change the calculation or guarantee savings.

Filing prototype — checkout unavailable

Checkout is unavailable. Browser-local, profile-scoped convenience gating is best-effort, not server-verified access. A URL or browser flag is not proof of payment. Clearing browser data removes local state; no account or cross-device recovery is provided.

Optional filing controls are a local prototype.

Checkout is unavailable. The reading above is complete; print, CSV and five local summaries are optional enhancements, not hidden answers.

Before using the replicate-range dial

Record three readings only when repeating a measurement is appropriate under your device's instructions or a clinician's guidance. Do not delay needed care to assemble a neat dataset. Keep each row to one device, one measurement site, one Celsius convention and one session; changes of site or device are different conditions, not interchangeable replicates. The parser supports signed Celsius values from -50 to 100 for arithmetic checks, not because that entire range is a plausible body temperature. Anonymous session codes are enough. A range describes dispersion; an average describes the center of the recorded set. Neither can establish calibration, infection, treatment need or an individual normal temperature.

Boundary and sources

Method: The range is max(first, second, third) minus min(first, second, third). The mean is their sum divided by three. Across sessions, this summary selects the largest range; adding ranges would have no useful temperature meaning. Review flags use a strict greater-than comparison with your entered spread mark, so equality is explicitly unmarked.
All sample records, dates, quantities and labels are invented. No outside policy, contract, rate, clock offset, measurement or accessibility standard is represented as verified.
Google’s official pricing documentation, fetched 2026-10-01, says AI Studio is free in available regions. Optional formatting may require a Google account; manual local entry requires none. Limits can change and free-tier content may be used to improve products. Do not send private records.

Optional AI formatting, never the calculation

Manual entry completes this replicate-range dial for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.

Format only these fictional or non-sensitive notes for a replicate-range dial. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string", "string"]}], "setting": "string"}. The columns are Session code | first °C | second °C | third °C; the setting is Reader-selected repeat-spread review mark (°C). Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.

An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
