Allegro helps you uncover what's triggering your allergies. Log reactions in seconds, see patterns emerge on a visual heatmap, and get daily risk forecasts based on real-time pollen and air quality data.
Unlike basic symptom diaries, Allegro learns from your history. After 10+ logged reactions, the prediction engine analyzes your personal triggers alongside environmental factors (pollen counts, AQI, even barometric pressure) to warn you before bad days hit.

What you can track:
28 common triggers including pollen types, dust, mold, pet dander, foods, and weather changes. 12 symptom types from sneezing and congestion to hives and fatigue. Rate severity, add medications, and attach notes.

See your patterns:
The heatmap reveals trends you'd never spot in a list: your worst months, peak reaction times, weekly rhythms. Built-in analytics surface your most common triggers and symptoms.
