Lipida: Cholesterol Tracker

Free, accurate LDL calculator with Friedewald and Martin-Hopkins methods — then track every cholesterol panel, see your trends, and sync with Apple Health.

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.

APPLE HEALTH SYNC • Read and write cholesterol values through Apple Health to keep everything in one place.

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 • Works completely offline. 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.
