Lipida: Cholesterol Tracker

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.
