Dark Sky has a graph of temperature changes for the next 24 hours along with precipitation information and when the sun rises and sets. It also gives quick access to day-by-day summary of the next week.
Dark Sky can tell you how many minutes you have before it starts raining, a snowstorm begins, etc. You adjust how many minutes beforehand it the app should send a push notification.
While the app's ability to predict weather conditions and when it will rain is on point, temperatures appear to be about 3-5 degrees warmer than what is actually recorded each day.
The app adjusts information such as distance of a storm, time until it starts raining, etc, based on your location that it can estimate within a few meters of your exact location.
With Dark Sky you can quickly get the most important predictions and current weather. The app shows information such as temperature (and how actually "feels" like and upcoming changes), humidity, wind, visibility, pressure, etc at a glance.
Yahoo Weather's main screen shows a enough information to get a good understanding of the upcoming weather without being too overwhelming. And it has radar, satellite and heat maps if you wish to get even more detailed information.
The app only allows the user access to the paid features for one year when purchased through an in-app-purchase. This can add up to an expensive app if used for many years.
Weather Underground crowdsources weather information. Anyone can set up a personal weather station and give that data to Weather Underground. A network of over 20.000 personal stations supplements roughly 10.000 National Weather Service stations. All collected data is run through a tool called BestForecasts that considers accuracy of 70 prediction models and creates a forecast from that process that's then presented to the end-user in a detailed way.
Weather Underground pushes an overwhelming amount of information at the user at first glance. Sometimes it is difficult to find exactly what you want on the go. Other applications such as Yahoo Weather are much easier to read. But the advantage to this is the wealth of raw information available.
A feature called Spark shows where lightnings take place by accessing real-time lightning monitoring information. You can then set it up to notify you when lightning has struck in a specific place or when a lightning storm is near your location.
The Weather Channel application allows you to input a starting point and destination on a radar map and then predict if you will encounter any type of storms along the route. The feature needs work and doesn't always work properly but the idea is promising if improved.
The Weather Channel widgets are attractive and functional. The widgets are available in 1x1, 2x2, and 4x1 sizes and even follow their own application's design language instead of following HTC like many others.
The Weather Channel app's maps provide a descent amount of radar options but the overall design is very confusing and the in app tutorial hint is useless.
The Weather Channel with its large TV presence offers an impressive amount of weather forecasts videos in the app. Although many of the videos in the app such as "Lady and the Shark!" have absolutely nothing to do with weather.
The overall theme of The Weather Channel app is bright with a consistent amount of Weather Channel blue. Fortunately the app also performs well. The app shares a similar design to the Google Play Store with scrolling tabs for "radar," "now," "videos," and "forecast." The scrolling tabs are very fluid and each tab is quick to load.
Solar has a colorful, clean interface and offers a 24-hour & 3-day forecast (accessed by swiping up or down respectively) with ability to switch between location by swiping horizontally. Each view displays only temperature, conditions, date, time and location.
Information can be displayed in a much more simple and streamlined format. While the graphical features are very cool and attract the eye, the app can also be visually distracting for someone who just wants the weather information conveyed to them as efficiently as possible.
There are constant, pertinent updates to the app and very few bugs or problems mar the experience. An extremely solid app exhaustively and lovingly maintained by an extremely talented developer (and genuine good bloke too).
