Several small user interface updates 4.0.1 10/14/2022 The EPA website has been unreliable, and the data format changes without any prior notification breaking the app. Therefore, this version utilizes the superb Apple Weather framework to provide the current UV Index.

In addition to the estimated hourly UV Index list view, the app will now display a temperature chart for the next eight hours.

Updates to support the latest hardware and the latest versions of iOS and iPadOS.

Small interface updates. 4.0 10/03/2022 This is a small update to check for a network connection and correctly inform the user when the app can not reach the Internet to receive UV-Index data from the EPA website. 3.0.6 09/10/2022 Oops! I missed the fact that the EPA website publishes dates with two digits days, and the App was filtering for single digits. Fixed now! 3.0.5 09/01/2022 The EPA website slightly changed the format of the data it provides, which made it impossible for the VBS UV-Index to get the current UV Index at the user location. Fixed now. 3.0.4 09/01/2022 Corrected a bug that would not display the correct color for a UV-index of 11 or more--purple. 3.0.3 06/29/2022 Corrected a bug that would utilize the default location (San Francisco) rather than the user's current location when the app first launched. 3.0.2 02/23/2022 Better error handling when the EPA Web site is down and not providing UVIndex forecasts.
Better error handling when checking for Internet connections. 3.0.1 02/17/2022 Complete re-write of the app to support the latest Apple iOS devices.

I finally noticed that EPA changed the way they delivered data which broke the old version. This version better supports future EPA changes.
The about screen now allows you to send a support email directly from the app.
