Works from your actual location. Everything you need in the way of local weather, with out all the bells and whistles that make a app cluttered and difficult to use. ### 5/5 — Excellent weather graphs *2020-01-12, version 1.1.0* This is A wonderful app. It provides easy to read weather data in graphical form. Simple, well done & free. Thank you! ### 5/5 — Intellicast replacement *2019-01-21, version 1.1.0* This app restores most of the functionality but simplicity that was present with the Intellicast app and website. Just a few improvements would really help - More data points, and a 10 day forecast. I’d also like to see the multi day forecast to show the highs and lows in one continuous line instead of linking all the highs together and all the lows together. This would give a better picture of when fronts are predicted to pass, etc. ### 5/5 — YES YES YES!!! *2018-11-21, version 1.1.0* The original “Storm” app by weather underground had this befroenthey were bought out. Since I have not been able to find anything like it. This is perfect, exactly what I need, and will allow me to see the real data to understand what is really likely to happen... I hate ‘predicted forecasts’ and fancy icons. ### 5/5 — Great App *2017-01-24, version 1.1.0* This app is useful in so many ways. It runs smoothly, is easy to use, and it has more detail than most weather apps. Good job Mark! ## Frequently asked questions about Precipitate ### What weather data does Precipitate display?
