## Description

Four transparent psychiatry calculators — PHQ-9/GAD-7 with trends, four-formula QTc, antipsychotic equivalence, and BMI/weight change. Offline, cited, no accounts.

Psych PocketCalc is a transparent clinical reference for psychiatrists, residents, NPs, and medical students. Four everyday calculators, zero black boxes: every result shows the formula used, the inputs you entered, the primary literature behind it, and its limitations — so you can verify the basis of every number yourself.

RATING SCALES — PHQ-9 & GAD-7
• Item-by-item scoring with the validated response anchors
• Published severity bands (Kroenke 2001; Spitzer 2006)
• Automatic flag when PHQ-9 item 9 is positive
• Score trends saved on your device only — no accounts, no cloud

QTC — FOUR FORMULAS SIDE BY SIDE
• Bazett, Fridericia, Framingham, and Hodges computed together
• The arithmetic for each formula is displayed, not hidden
• Sex-specific thresholds (>450 ms men, >460 ms women; ≥500 ms high risk) per AHA/ACCF/HRS 2009
• See at a glance when formula choice changes the clinical picture

ANTIPSYCHOTIC EQUIVALENCE — YOU PICK THE METHODOLOGY
• Gardner 2010 international expert consensus (chlorpromazine-100 equivalents)
• WHO Defined Daily Dose method (Leucht 2016)
• Conversion basis shown for every estimate
• Honest gaps: drugs missing from a dataset say "No data" — the app never silently guesses

BMI & WEIGHT CHANGE
• WHO BMI categories with the calculation shown
• Percent weight change from baseline, with the ≥7% clinically significant antipsychotic weight-gain threshold (ADA/APA 2004)
• Metric and imperial units

PRIVATE BY ARCHITECTURE
• 100% offline — the app makes no network requests at all
• No login, no ads, no analytics, no trackers
• Nothing you enter ever leaves the device
• Optional score history is stored locally and deletable any time
• Share/copy exports contain scores, formulas, and citations — never identifiers

BUILT FOR ACCOUNTABILITY
• Every formula is unit-tested against manually computed examples
• Every module cites its primary sources and states its limitations
• A "Last clinically reviewed" date is shown in the app

Psych PocketCalc is an educational reference for clinicians and trainees. It does not diagnose, treat, or recommend therapy, and it is not a substitute for clinical judgment, manual ECG measurement, or institutional protocols.
