WeatherBrush, built by Faction Studio, is a no-cost iOS app that takes the guesswork out of daily styling by providing users with real-time weather data for their location. This includes current conditions as well as both hourly and 7-day forecasts.

Users can take daily selfies and use the app to help them choose the ideal hair style based on prevailing or predicted weather conditions. The brilliant Diary feature helps users learn how they should style their hair based on prevailing or predicted weather conditions. The Diary also allows the user to find their best look based on similar weather. Users can also set reminders to take selfies throughout the day and send snapshots of their best looks to friends via social media.
