About 4n6 Tools Lite
4n6 Tools Lite is the basic edition of 4n6 Tools Pro, professional calculators for forensic medicine built from everyday autopsy and external-examination practice. Seven tools work fully in Lite. You can open all the others as a preview and see what the full version offers. FULLY WORKING IN LITE • Henssge rectal-temperature nomogram: time since death with a 95 % interval, the date and time of death and a timeline • Post-mortem interval from vitreous potassium: four published methods • Traub index (glucose + lactate): ante-mortem glycaemia • BMI and nutritional status • Body surface area (BSA) and expected heart weight • Age from aortic circumferences • Unit converter (mg/dL ↔ mmol/L and more) for common analytes or a custom molar mass PREVIEW OF THE PRO TOOLS Tools marked Pro can be opened and browsed in Lite: the form, the method and the references.

THE FULL PRO VERSION 4n6 Tools Pro unlocks all 27 tools: post-mortem changes, forensic entomology, post-mortem toxicology (interpretation of ethanol and 67 substances against published reference levels), burns, blood groups and stains, skeletal sex and age, DVI, forensic odontology, photogrammetry, colorimeter, desmin immunohistochemistry and microscopy, plus a shared case report and case backup. A one-time purchase, no subscription. FEATURES • Light and dark mode • Results with an interval scale • Twelve languages: Slovak, English, Czech, German, Italian, French, Ukrainian, Polish, Hungarian, Chinese (Simplified), Spanish and Portuguese (Brazil) • Works offline, entirely on-device: sends nothing and collects nothing • Methods and references with every tool • Adjustable text size, including Dynamic Type FOR WHOM Physicians and specialists in forensic medicine and pathology, examining physicians, expert witnesses and, for teaching, medical students. IMPORTANT All results are orientational and based on published methods. The app is not a medical device and does not replace the professional judgement of the examining physician or expert.
