About

Runny day

Features
Read full description

Runny day is a calm, private diary for tracking allergy-like symptoms and the context around them. Log symptoms, meals, medications, outdoor exposure, and everyday observations in one timeline. Add local pollen, air quality, and humidity when you choose to use location or select a city. As you build a record, Runny day highlights possible recurring patterns based on your own entries. It explains what was observed and keeps uncertainty clear β€” it does not diagnose allergies, identify causes, or replace medical advice. Use reports to bring a concise history to a healthcare conversation. Features: β€’ Symptom, food, medication, and exposure logging β€’ Optional pollen, air-quality, and humidity context β€’ Explainable observation-based pattern insights β€’ Custom date ranges and doctor-friendly summaries with Premium β€’ Local-first data storage and privacy controls Runny day is for personal observation, not diagnosis or treatment. Seek qualified medical guidance for medical questions or urgent symptoms. Premium is available as a weekly or yearly auto-renewing subscription, or as a one-time lifetime purchase. Prices are shown in the app before you buy. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in App Store settings.
