Description
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.
