Dialedin.bio — Blood Test PDF Trends & Symptom Correlation

Upload lab PDFs, log how you feel, see what lines up

Problem

Users' blood test results are scattered across different hospitals and apps, making long-term trends hard to see. They also want to know if there's a correlation between how they feel and their lab numbers. Manually entering PDF data into Excel to chart it is painful, and aligning subjective questionnaires with objective data is nearly impossible.

Solution

A web app that lets users upload lab PDFs, automatically extracts key metrics, and generates trend charts. Users log how they feel daily via a simple questionnaire (energy, sleep, pain, etc.), and the system overlays subjective scores onto the metric curves, calculates correlations, and highlights unusual patterns.

Users

Consumers with chronic health issues or those focused on long-term health who get regular blood tests.

MVP

PDF upload and OCR extraction of core metrics; time-series charts for metric changes; daily short feeling questionnaire; overlay questionnaire scores on the same timeline as metrics; export PDF report for doctors.

Revenue

Freemium: basic features free, advanced analytics (correlation, unlimited history) via monthly subscription; or one-time purchase for a local version.

Why now

Personal health data awareness is growing, but existing tools either target hospitals or only track single metrics. Indie developers can quickly build an MVP using off-the-shelf OCR and charting libraries without needing medical licenses.
