Read full description

Zephyr watches pollen levels in your city and reminds you when it suits you best before a peak — the evening before so you can take your antihistamine in advance, or the morning of the peak so you don't forget to take it before heading out. Built for allergy sufferers who are tired of riding out flare-ups: pollen peak expected tomorrow? The app tells you at the time you choose — either the night before or first thing in the morning. Features: • Daily pollen index for 9 species (birch, grasses, ragweed, olive, ash, etc.) • 5-day forecast • Interactive concentration map • Reminder the evening before, or the morning of the peak — your choice • Monthly dose log • iOS widgets for a quick glance from your home screen • Data from the Google Pollen API 100% local. No account needed. No ads. No data sent anywhere other than Google Pollen to fetch the forecast. Designed for users who want to anticipate their allergies, not endure them.

Try Anthos free for 7 days — no payment until you decide. Anthos doesn't just tell you the pollen count. It learns the exact pollen count where YOUR body starts reacting — then warns you when conditions cross your personal limit. WHAT MAKES ANTHOS DIFFERENT ◆ Your Personal Threshold — After a week of logging how you feel, Anthos calculates the precise pollen count where your symptoms begin. Today's count is shown next to your personal limit, so you know instantly if you're in safe territory or trouble. Confidence grows as you log more days. ◆ AI Daily Reading — A personalized morning briefing that explains how today's air affects your day, in plain language. ◆ Body Decoder — Connect Apple Health to see how your sleep, HRV, and resting heart rate line up with your symptom days (with your permission). ◆ Tomorrow's You — Your personal 7-day outlook, built from your own logged history. ◆ Anthos Score — One number (1–100) that combines pollen, air quality, and weather into a single glanceable metric. ◆ 15 Tracked Allergens — Oak, Birch, Grass, Ragweed, Cedar, Maple, Ash, Cottonwood, Alder, Olive, Hazel, Pine, Elm, Mugwort, and Mold. ◆ Safe to Open Windows? — A simple YES or NO with context and timing suggestions. ◆ Best Day This Week — Highlights the lowest pollen day in your 5-day forecast. ◆ Cross-Reactivity Alerts — When Birch pollen is high, get a heads-up about apples, cherries, and hazelnuts (oral allergy syndrome). ◆ Personal Triggers — After a week of logging, Anthos shows which allergens line up with your worst symptom days. ◆ Storm Surge — A heads-up when thunderstorm conditions can trigger sudden pollen-burst reactions. ◆ Pollutant Breakdown — See PM2.5, Ozone, NO₂, SO₂, and CO levels individually. ◆ Wildfire Smoke Detection — Alerts when particulate matter suggests smoke in the air. ◆ Smart Notifications — 9 alert types including per-allergen spikes, ozone warnings, thunderstorm pollen bursts, and barometric pressure drops. ◆ Symptom Logging — Track sneezing, itchy eyes, congestion, and fatigue daily. ◆ Medication Tracker — Log the medications you already take (personal log only). ◆ 30-Day Summary Export — One-tap symptom history to share with your healthcare provider. ◆ Shareable Daily Card — Branded card sized for Instagram Stories. ◆ Home Screen Widgets — Small, medium, and lock screen widgets. ◆ Siri Shortcut — "Hey Siri, how's my pollen today?" ◆ Season Countdown — Know when ragweed season starts and how many days are left in grass season. PRIVACY Your location is used only to fetch local pollen, air quality, and weather data. Your symptom logs and medication entries stay on your device. To write your AI Daily Reading, Anthos sends your allergen profile and local conditions to Anthropic's Claude. If you turn on Apple Health features, the health signals you choose (sleep, HRV, resting heart rate) and your symptom-based thresholds are included only with your explicit, separate consent — never used to train AI models, and deleted within 30 days. You can revoke consent anytime in Settings. Anthos is not a medical device and does not provide medical advice, diagnosis, or treatment. SUBSCRIPTION 7-day free trial, then $3.99/month or $29.99/year (save 37%). Payment is charged to your Apple Account after the free trial unless canceled at least 24 hours before it ends. Manage or cancel anytime in Settings. Terms: https://anthosair.com/terms Privacy: https://anthosair.com/privacy
