Tempus, derived from the latin word for weather as well as latin for time, so I guess now is the time for another weather app! Tempus is a simple and minimal weather app that isn't full of unnecessary features. Tempus was built to be easy to read and easy to use. Features include: - Current local weather - Celsius and Fahrenheit - Min & Max Temp throughout the day - Humidity, Wind Speed, and Direction - 5 Day forecast for your area - Weather Alert Notification - Faster data retrieval All of the photos are property of me and were taken with my iPhone while riding my bicycle around the Berkshires.

Do you love storms as we do? Then you’ll love our app. At photorealistic globe you can see real time lightning all around the world. Besides accurate day and night cycle, globe contains real time clouds, precipitation and lightning history layer for last hour. For better resolution you can zoom into map detail. If you zoom really closely to your location, you can use start-stop feature to measure your distance from nearby storm. When no storm is close enough, feel free to “stream” lightnings via your camera flash from opposite side of the world to your living room. ...and one more thing: If you try hard enough we are pretty sure that you’ll find switch for real time aurora. Not as cool as lightning, but also kind of amazing!

Verdict
The clearest difference is review sentiment: Tempus at 100% against Thunderly's 58%. Tempus also leads on rating (4.7 vs 4.3) and update cadence (every 6 days vs every 3 weeks). Thunderly's advantage is ratings volume (2.6K vs 29) and iOS requirement (11.0 vs 14.4). On price, ads, in-app purchases and monetization model there is nothing between them.
