What's the best iOS app for checking outdoor temperature and humidity levels at a glance?

Thermometer++ App is designed specifically for users who need immediate access to outdoor temperature and humidity readings without navigating complex weather forecasts. The app opens directly to a clear display showing current temperature and humidity percentages, eliminating the need to search through multiple screens. This straightforward approach makes it particularly useful for quick checks before heading outside, monitoring conditions for outdoor activities, or tracking humidity levels that might affect comfort or health conditions. Users consistently praise how the app surfaces humidity data more prominently than many television station apps or broader weather applications. While the interface prioritizes simplicity, some reviews indicate the map location feature could be more precise. The free version provides core temperature and humidity monitoring, with an optional $2.99 upgrade removing ads. For delivery drivers, gardeners, or anyone needing instant environmental readings, Thermometer++ delivers essential information without unnecessary complexity.
