Hazard Notifier is a unique, highly customizable application, specifically developed to deliver information concerning potentially unsafe events in a simple yet straightforward way. With push notifications and distinctive sounds, Hazard Notifier sends the information you want to know directly to your phone, clearly and informatively. All you have to do is open the application and you can immediately watch and track developing hazards on a map in relation to your location. With weather radar and hazard icons, you will be able to see exactly what is going on and where. When using the application, you are completely free to adjust the range of the area in which you wish to receive notifications, as well as choose what kind of hazards you would like to be notified of. In addition, Hazard Notifier’s exclusive reporting service allows users to report events that have just begun to occur around them, which can help notify others about possibly unsafe events before they have even been formally declared. This application is not just limited to reporting weather. Hazard Notifier reports events involving: • Tornadoes • Severe Thunderstorms • High Winds • Hail • Lightning • Flooding • Heavy Rain • Snow • Freezing Rain • Ice • Dense Fog • Dust Storms • Fire • Hurricanes • Tropical Storms • Earthquakes • Tsunamis • Volcanoes • Debris Flow • Asteroids With Hazard Notifier, you will not have to spend as much time sifting through slews of disorganized information on the latest environmental events from news programs and web pages. Hazard Notifier will clearly display events in relation to where you are. If you find yourself wishing to stay informed of turbulent conditions, yet are unable to actively access the latest weather or news reports, Hazard Notifier will send you push notifications of potentially unsafe events in your area.

Waterscope is a weather app for people who love being around water. Whether you're surfing, fishing, boating, or just taking the dog for a walk on the beach, Waterscope will keep you informed about your local conditions. The data presented comes from the National Oceanic and Atmospheric Administration (NOAA) and National Weather Service (NWS). This app would not be possible without the scientific contributions from the people at these valuable public institutions. The app uses a series of screens to present this information: HOME When you launch Waterscope, you'll be presented with a screen that shows a graph of high and low tides for the nearest measuring station. Below that are wave heights and water temperatures for the closest NOAA buoy. These are followed by wind speed and air temperature measurements for a nearby NWS weather station. Above the graphs, you'll see the current phase of the Moon and its position on the horizon. Below you'll see the sun's position relative to your location on Earth. The clock at the bottom shows the current time, or the time for past data samples and future forecasts. Tap on the clock to scroll back to the current time. Tap on any large blue ring to show more information. Smaller blue rings make adjustments to what you're currently viewing. Tapping on the icon in the upper-left corner will show an overlay that explains the symbols and markers. EARTH The Earth view shows the last 24 hours of satellite imagery near your current location (the small blue dot is you!) Tap the + button to see a larger version of the latest image. The hurricane symbol at the top of the view will show the latest forecasts from the National Hurricane Center. MOON The Moon view shows the phase and location of the Moon for the next year. The white dot shows the height above the horizon, and when you align the blue arrow with the centerline and look up you'll see Earth's biggest satellite :-) SEA This view of the sea shows markers for observations collected by the National Data Buoy Center. The arrow points in the directions waves are heading: tap it to show water temperature, wave height, and an average period between waves. To make any buoy's data show up on the home screen, tap the heart icon. LAND Like the view of the sea, but with onshore observations collected by the National Weather Service. The arrow shows wind direction and tapping the marker shows the air temperature, wind speed with gusts, and barometric pressure. Tap the heart to add it to home. TIDE This view shows nearby tide stations: tap on any marker to get the current prediction at that location. Like the other map views, the tide station can be added to the main screen using the heart icon. FORECAST If you move forward in time, you'll see a forecast for air temperature and conditions. Tap on the conditions to get an expanded view that includes wind speed and direction.

Verdict
The clearest difference is in-app purchases: Waterscope Weather at none against Hazard Notifier's 1. Waterscope Weather also leads on rating (4.2 vs 3.8) and ratings volume (24 vs 8). Hazard Notifier's advantage is update cadence (every 2 months vs every 5 months). On price, review sentiment, ads and device support there is nothing between them.
