Aletheia: Acne Tracker

A breakout doesn't show up on the day you caused it. Dairy can surface a week or two later. A stress spike works through cortisol, sebum, and inflammation before anything is visible, sometimes a full month. By the time you see it, the cause is buried in two weeks of ordinary days you've stopped thinking about. That lag is why keeping a notebook never worked. It's also the entire reason Aletheia exists. HOW IT WORKS Log your day in under a minute: skin rating, stress, sleep, water, diet. Apple Health fills in resting heart rate, HRV, steps, and sleep automatically. When you record a breakout, Aletheia looks backwards through windows sized to each factor's biology, then compares those windows against your own clearer days. The result is a list of what actually precedes your breakouts, ranked, with the lag each pattern was strongest at. SCAN YOUR FOOD Point the camera at a barcode and get two scores side by side. A research score from published data, and a personal score built from your own logs. Every other app tells you what breaks out most people. Aletheia learns what breaks out you. Ingredients are parsed in label order with the flagged ones marked. Anything you scan can be tracked as a trigger. WHAT YOU GET Daily skin score and logging streak Breakout logging by type, facial region, and severity Custom triggers for anything the built in factors miss Findings staged as Early Signal or Confirmed Pattern, so a hunch from three days isn't dressed up as a conclusion 14 day elimination challenges to test a suspected trigger Plain English explanations of every pattern found Trend charts and a weekly summary Apple Health autofill, read only Full data export and in app account deletion HONEST ABOUT LIMITS Confidence is capped. A food that has been examined and not linked scores 82, never 100, because "we found nothing" is not "this is fine." AI analysis is off until you turn it on, and the consent screen itemizes exactly what is sent. Aletheia is not a medical device and does not diagnose or treat any condition. Health claims in the app carry citations you can check. SUBSCRIPTION Aletheia Premium is $4.99 per week. Payment is charged to your Apple Account at confirmation of purchase.
