I have another build of my Fast Weather app available for testing. Build 19 has a fairly robust set of features and fixes. You can try the app at:

Further notes:
***Important***
Some settings have changed so if you are not finding the data you expect, please open Settings and use Reset at the bottom of the page to get the updated settings and defaults. This will not delete your existing cities.
***New*** (1/5)

Available on iOS

*A use my current location is now available when adding a new city.
*If you want to read some *really* cold temperatures, browse under international and add some of the newly listed Antarctica weather stations. (2/5)

*Extensive cleanup of settings to organize and allow for greater customization of the details in each major category--City List, Today's Forecast, Weather Alerts, 24 Hour Details, 16 Day Details and more. Use VoiceOver actions on the headings for each category in settings to adjust the order of the category.
*Expected Precipitation, Historical Weather and Weather Around Me now on by default and not behind the developer Settings option.

***Changes and Fixes*** (3/5)

*Precipitation section for city details removed. This data was supposed to show actual amounts of precipitation at a given time but was not working. You can still view many details around the expected precipitation in both hourly and daily details.
*Better identification of the general category of precipitation and specifics for rain and snow.
*Performance improvements throughout the app.

***Test Notes*** (4/5)

*Please try the full app experience. There are a number of under-the-hood improvements for performance and reliability as well as the previously mentioned changes to settings.
*Feedback on any visual issues/glitches or quirks in the app is appreciated. I'm using AI description services and my own understanding of how various controls should show information but the app has had limited actual sighted review. (5/5)
@kellylford The only thing I can say at the moment: This app is absolutely amazing! Give it a try. This app is not leaving my phone. This is the only app where I can get an accessible look at the weather on a certain day over 20 years. I'm in Canada and the data is wonderful. The only thing I would love it to do is have the ability to get marine and aviation forecasts. How easy would this be to implement? Let me know if there is anything I can do. This app is totally awesome!
@douglawlor Thanks for the kind words. I will have to see about those types of forecasts and what sources exist to use.
