For Good Measure vs Echo Quant

For Good Measure is an offline-capable echocardiography reference for clinicians who need to look up guideline-based reference values quickly in everyday clinical practice. Not a medical device. The app makes no diagnoses, gives no patient-specific recommendations, performs no calculations on patient data, and does not replace clinical judgement. It displays only general reference information derived from published guidelines — and is intended exclusively for qualified medical professionals. FEATURES • Five parameter types – reference ranges, graded parameters, severity tables, score tables, and decision algorithms • Full-text search – instant search across all parameters and categories • Favorites – mark frequently used parameters for quick access • Sex-specific values – switch between male and female reference ranges where applicable • Cross-references – navigate between related parameters • LV segment model – the left-ventricular segments at a glance • Source citations – every parameter links to its guideline; tapping "Quelle" fetches the guideline PDF directly from the publisher (kept in memory for the current session only); if retrieval fails, the DOI is copied to the clipboard • Bilingual – full interface and clinical content in German and English, switchable in Settings (German is the source of truth) • Dark mode – a Material 3 dark theme optimized for the clinical environment • Offline-capable – all reference data ships inside the app; the network is used only for the optional guideline-PDF retrieval DATA MINIMIZATION No user accounts, no ads, no tracking, no analytics or crash-reporting SDKs, no patient data. The app collects and transmits no personal data to the provider. The only network feature is the user-initiated retrieval of a guideline PDF directly from the respective publisher's server. SOURCES Reference values are based on published society guidelines (including ASE, EACVI, ESC, BSE, SIECVI, and the German AWMF S2k TTE guideline). The applicable original guideline always prevails; every value must be verified against the original source before clinical use. All information is provided without warranty.

Stop scribbling continuity equations on scrap paper. Echo Quant turns raw TTE measurements into graded, report-ready numbers — in seconds, fully offline. Built for medical students, residents, cardiology fellows, and cardiac sonographers learning echo quantification. EIGHT GUIDED MODULES • Aortic Stenosis — continuity-equation AVA, indexed AVA, DVI, gradients • Aortic Regurgitation — PISA, EROA, regurgitant volume, vena contracta • Mitral Stenosis — pressure half-time and deceleration-time MVA • Mitral Regurgitation — PISA quantification with integrated grading • Pressures — RVSP/PASP, PAEDP, mPAP, PVR, estimated LAP • Chambers — sex-specific normal ranges with report-ready output • Tricuspid & Pulmonic — stenosis and regurgitation quantification • Diastolic Function — the ASE grading algorithm, variable by variable WHY TRAINEES KEEP IT ON THE HOME SCREEN • Severity meters grade every value live against published ASE-style thresholds • Every module shows its formula — learn the math while you use it • One-tap, copy-ready report lines for practice reads • Fully referenced: every formula cites its published ASE/EACVI guideline source, with links PRIVATE BY DESIGN Works completely offline. No account. No ads. No analytics. No data collection — everything stays on your device. IMPORTANT Echo Quant is an educational reference only. It is not a medical device and is not intended for diagnosis, treatment, or any clinical decision-making. Always verify values independently and follow current society guidelines and institutional protocols.
