For Good Measure vs Echodex

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.

The TTE values you look up every day — graded, color-coded, and cited — one tap away. Built by a cardiologist for the reading room. WHO IT'S FOR Cardiologists, cardiology fellows, sonographers, and any clinician who performs or interprets transthoracic echocardiograms — at the scanner, in the reading room, or on rounds. FIND IT FAST Six color-coded sections — Chambers, Stenosis, Regurgitation, Diastology, Pericardium, Formulas — one tap from the top of every screen. Severity ramps make mild vs moderate vs severe legible at a glance. Star the cards you use most and they pin to the top. COMPLETE COVERAGE • Chambers: LV size and function, LV mass, RV, atria, aortic root, IVC → RA pressure • Stenosis: aortic, mitral, tricuspid, pulmonic — velocities, gradients, valve areas • Regurgitation: vena contracta, EROA, regurgitant volume and fraction for all four valves • Diastology: the 2025 cut-points and the exceptions where they don't apply • Pericardium: tamponade, constriction, constriction vs restriction, effusion grading • Formulas: Bernoulli, continuity, PISA, volumetric, right- and left-sided pressures BUILT FOR THE BEDSIDE Works fully offline — no login, no ads, no data collection. Light and dark themes. Follows your system text size. EVERY VALUE CITED Every card carries superscript markers that jump to the full citation, straight from the ASE, EACVI, and ACC/AHA guidelines: chamber quantification (2015), aortic stenosis focused update (2017), valve stenosis (2009), valvular heart disease (2020), native valvular regurgitation (2017), diastolic function (2025), and pericardial disease (2013). FOR CLINICIANS For licensed clinicians and trainees. The app performs no calculations, stores no patient data, and makes no diagnosis; it is not a substitute for clinical judgement or the source guidelines.
