Whengo is a weather tracker for people who feel the weather more than most. If heat wears you down, poor air bothers you, or strong sun is something you watch, Whengo checks the forecast against your own limits, hour by hour. Set your limits once: • Feels-like temperature range • Humidity range • Wind speed limit • Precipitation chance limit • Air quality ceilings for ozone, PM2.5 and PM10, from four presets or your own numbers • UV index limit • The times of day and days of the week you care about Whengo scores every hour of the next seven days against those limits and shows the stretches where everything fits. When nothing fits exactly, it shows the closest matches and marks them. WHAT YOU GET • Hour-by-hour scoring. A mild afternoon with an ozone spike or a midday UV peak shows up for what it is. • Feels-like first. Temperature is scored on how it feels, with humidity, wind and sun factored in. • Air quality and UV next to the weather. Hourly ozone, PM2.5 and PM10, each rated in its US EPA Air Quality Index category, plus the UV index, in one view. Air quality forecasts reach about four days ahead. • Details for every window: feels-like trend, humidity, wind, rain chance, air quality and peak UV. • An optional heads-up notification before your next matching window. • Add any window to your calendar, with the conditions written into the event. • Your location or any US zip code. Times show in that place's own time zone. Temperatures are in °F and wind in mph. FREE, WITH ONE OPTIONAL UPGRADE Everything above is free. Whengo Pro is a one-time purchase, not a subscription, and adds: • A Home Screen widget with your next matching windows • Unlimited profiles, each with its own limits. Keep one for yourself and one for someone who handles heat differently. Buy once and restore it on any device signed in to the same Apple Account. PRIVATE BY DESIGN No account, no ads, no tracking. Your preferences stay on your device, and your location is used only to fetch your forecast. Forecasts can change quickly, so check official advisories when conditions matter to you.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Widgets look right on Clear and Tinted Home Screens and give Moderate air quality its own symbol. A mistyped zip code now says so instead of loading somewhere else, and a few buttons are easier to tap.
