About

Lipida

Read full description

Lipida is a focused, private cholesterol tracker built around a free, accurate LDL calculator. Enter your Total Cholesterol, HDL and Triglycerides and get your LDL in seconds — calculated with both the classic Friedewald equation and the more accurate Martin-Hopkins method, which gives you a better estimate at low LDL and high triglyceride levels where the old formula falls short. FREE LDL CALCULATOR • Two methods side by side: Friedewald and Martin-Hopkins. • Also computes non-HDL cholesterol and your Total:HDL ratio. • Clear, color-coded risk bands so the numbers actually mean something. TRACK EVERY PANEL • Save each result as a dated lab panel and build a complete history. • See where you started and where you are now at a glance. SEE YOUR TRENDS • Charts for LDL, Total and HDL over time. • Spot the direction of travel between tests, not just a single snapshot. STAY ON SCHEDULE • Set a local reminder for your next lab test so you never miss a check-up. PANEL REPORTS — OPTIONAL ONE-TIME PURCHASE • Preview saved panels for a date range for free. • Unlock PDF and CSV exports with a single purchase. No subscription. • Calculator, history, trends, reminders and PDF import remain free. • Blood cholesterol panels stay in Lipida; Apple Health does not provide a serum cholesterol type. US AND INTERNATIONAL UNITS • Full support for both mg/dL (US) and mmol/L (Australia and UK). • Switch units anytime — the math stays correct. PRIVATE BY DESIGN • Tracking works offline. Purchases and restore require the App Store. Your data stays on your device. • No ads, no accounts required, no tracking. Lipida is an informational tool, not a medical device, and not a substitute for professional medical advice. Always talk to your doctor about your results and any decisions regarding your health.
