HTC's weather app reigns on Google Play
The app has already been updated for the flagship HTC One (M8) and the new HTC Desire EYE. It offers 7 hour to 14 day forecasts, and includes some rather nifty weather animations along with the latest weather news. AccuWeather.com is the source of the weather information used on the app.
Other HTC system apps in the Google Play Store include the BlinkFeed social and news feed, HTC Lock Screen and HTC Gallery to name a few.
