Cholesterol Tracker

About this app

Cholesterol Tracker is the private, ad-free way to log your lab results and watch your cholesterol trend over the years. Everything stays on your phone. No account. No internet. No tracking. No ads. Ever.

Most cholesterol apps push ads next to your medical data or send it to their servers. This one doesn't. It doesn't even ask for the internet permission.

WHAT YOU CAN DO

• Log a full lipid panel in seconds — total cholesterol, HDL, LDL, and triglycerides, with an optional note.
• Watch your numbers trend over months and years with a clean, elegant chart.
• See instantly whether you're in the healthy range — every metric is classified against the NCEP ATP III clinical cut-points used by doctors.
• Miss the LDL number on your report? The app estimates it for you using the Friedewald formula (marked as an estimate, so you always know).
• Track the ratios that matter: TC/HDL, LDL/HDL, and TG/HDL (an insulin-resistance hint many apps ignore).
• Switch between mg/dL (US) and mmol/L (International) at any time. Your data is stored in one canonical unit, so switching is lossless.
• Optional local reminder when it's time for your next test (3, 6, or 12 months since your last panel). No push server — the reminder runs entirely on your phone.
• Export a printable PDF report to hand to your doctor.
• Export and import a JSON backup — your data belongs to you, not us.
• Built-in Learn section explaining what each number means in plain English.
• Full dark mode.

PRIVACY, SPELLED OUT

• No internet permission. Your data physically cannot leave your phone.
• No account, no sign-in, no cloud sync.
• No ads. No trackers. No analytics.
• The only permission the app requests is notifications — and only if you turn the test-reminder on. Even then, the reminder runs locally.

WHO IT'S FOR

• Anyone told by their doctor to keep an eye on their cholesterol.
• People on statins or a diet plan who want to see if it's working.
• Anyone who thinks their health data shouldn't be a lead magnet.
