About

Sonolex

Read full description

Sonolex is the structured echo case logbook built for cardiology training programs. Echo cardiology requires logging hundreds of cases during training. Sonolex replaces handwritten logs and spreadsheets with a fast, clinically organized workflow. LOG CASES IN SECONDS Enter echo findings using natural shorthand โ€” the same notation you already use. Type "ef 55 mild mr tr mild rvsp 40 ivc flat" and Sonolex instantly parses it into a structured report: LVEF, valve findings, PASP, and IVC collapsibility โ€” organized by system. BUILT-IN CLINICAL CHECKS Sonolex applies ASE-guideline logic to grade diastolic dysfunction and generate heuristic impressions. Labels are always marked as heuristic โ€” never overstated as AI. SUPERVISOR REVIEW WORKFLOW Send any case for digital co-sign. Your supervisor reviews findings on the web or iOS and signs off โ€” building an auditable record for your training portfolio. NBE-READY EXPORT Export your complete case log as a CSV compatible with NBE requirements. One tap, no reformatting. PRIVATE AND OFFLINE-FIRST Cases are stored on your device. Nothing leaves your phone without your explicit action. Requires iOS 17 or later.

NephX is a secure messaging platform built exclusively for the nephrology community in India. WHY NEPHX EXISTS Every brilliant case discussion, every academic insight that happens in WhatsApp threads โ€” most of it disappears. NephX exists to preserve the collective wisdom of Indian nephrology, structured and searchable for the next consultant, the next fellow, the next decade. WHAT'S INSIDE - Case discussions with structured threads and searchable archives - Voice and video calls โ€” one-tap, with colleagues anywhere in India - Academic meetings โ€” host journal clubs, CME, board meetings (recorded + transcribed) - Status updates โ€” quick clinical posts visible for 24 hours - Document and DICOM sharing โ€” radiology, lab reports, scans - Live location for emergency consults - End-to-end encrypted transit, encrypted at rest VERIFIED DOCTORS ONLY NephX is free, but access is gated by manual verification. Our admin team verifies medical credentials against Medical Council registries before activating each account. Patient confidentiality is a first-class design constraint, not an afterthought. NOT A MEDICAL DEVICE NephX is for peer academic discussion only. It is not a medical device, not a diagnostic tool, and not intended for direct patient care. BUILT BY THE NEPHX TEAM Developed by GeeApps for the Indian nephrology community. Free forever for verified members. Questions?
