LDL-Daily Tracker
A simple, sticker-style tracker for the specific biomarkers that move with diet — LDL-particle count, ApoB, triglycerides — so users can see if the avocado-and-oats plan is actually working.
Quantified-self adults in Germany monitoring cholesterol between Bluttests
- Photo-log of Befund PDFs so trends are visible across multiple quarterly labs
- Food-vs-biomarker correlation view (e.g. 'your LDL-P dropped after 3 weeks of daily oats')
- Reminders aligned to typical German check-up cadence (U-Untersuchung, Hausarzt-Jahrescheck)
- Export a 1-page PDF for the doctor visit
The trend highlights LDL-particle counts — a metric most generic fitness apps ignore — so there's a clear opening for a biomarker-specific companion.
ApoB/LDL-particle interest is real and growing in cardiology, but daily 'sticker' tracking between infrequent Bluttests (typically 3-6 months apart) targets a narrow quantified-self niche in DE; could not confirm live search volume.cholesterol tracker app ApoB LDL-particle at DuckDuckGo ↗
Cronometer and Levels Health cover adjacent metabolic tracking but no consumer app focuses specifically on LDL-particle/ApoB with German-language nutrition feedback; gap exists but Levels (US-only, CGM-centric) signals the model is hard to localize.https://www.google.com/search?q=ApoB+LDL+tracker+app ↗
Health-tracking apps convert poorly outside CGM/glucose verticals; German consumers are price-sensitive and routine lipid panels are covered by insurance, reducing willingness to pay for a tracking shell.https://www.google.com/search?q=ApoB+LDL+tracker+app ↗
ApoB as a superior cardiovascular risk marker is a durable clinical trend (guidelines shifting), but the core mechanic (logging between rare blood tests) limits daily engagement and creates churn once a result is logged.
Simple data-entry + charting app; no clinical integration, lab parsing, or hardware required; MVP is well within indie scope.
