Location does nothing. Interface is janky. Other apps do this far better and it’s not their only focus. Not recommended unless they hire competent coders. Not the case currently. ### 2/5 — Broken *2026-04-30, version 7.0.0* Stopped working ### 2/5 — Lots of room for improvement *2024-07-29, version 7.0.0* The app has some good information that can give you an accurate baseline, but it certainly has LOTS of room for improvement. Other than your location, there are ZERO personal factors taken into account. That might work well for some people, but I’m a natural redhead with light blue eyes and an extremely pale complexion, living in southern Florida, and I need an app that takes that into account. I read through all the EPA’s UV calculations, which consider wavelength, elevation, angle of the sun, ozone depletion, cloud cover, etc, but then only use some unknown “average” to calculate the sensitivity of human skin. Why bother being so accurate with your locational calculations to then turn around and assume every person is exactly the same? I really wish the EPA would realize that people are also as unique as locations, and that absolutely NEEDS to be taken into account. ### 2/5 — No notifications *2024-06-26, version 7.0.0* Unfortunately there doesn’t seem to be a way to configure notifications when the UV is about to go over a certain chosen level. Additionally the data appears to sometimes be unavailable. ### 3/5 — Useful but there are glitches *2024-04-13, version 7.0.0* The app is very useful, especially the hourly forecast, but the daily map has some technical issues. First, one cannot read the scale on the map; second, the dates for the maps change when the orientation of the ipad changes from portrait to landscape; third, the map is rather small and cannot be enlarged on the screen. ### 4/5 — Works fine *2023-08-20, version 7.0.0* Rough around the edges but works fine Wish there was an apple watch widget ### 3/5 — Doesn’t seem accurate *2023-03-28, version 7.0.0* This consistently shows much higher uv index than my other apps. It may be that this is the only accurate one, but it is more likely that it is inaccurate. ### 3/5 — Please update this app *2017-11-11, version 4.1* I use it on a daily basis however some days it is completely unresponsive. There is nothing you can do to get it to work. ### 3/5 — Few Issues, Overall Great App *2017-11-04, version 4.1* Everything seems to work fine except the hourly forecast. This feature worked for only one day, the day I downloaded the app. I would appreciate if you would please fix this bug. ### 2/5 — Unreliable *2017-08-09, version 4.1* Great app when it works. But when I need it the most it is inaccessible. ### 4/5 — Love the app, just not working *2017-07-13, version 4.1* Have used this app over the past year and love it. However recently it isn't working. Just displays blank screen ### 2/5 — No longer getting a data from database!!! :( *2017-06-12, version 4.1* I'm so sad that no longer getting any data.. ### 3/5 — please update this app !! *2017-06-07, version 4.1* would be 10 stars for sure if i didn't keep getting "forbidden access" error messages every time i click anywhere on the screen -- it works 10% of the time -- but when it does .. IT IS AMAZING ! this app has the potential to negate having any other UV Index apps ... PLEASE UPDATE for bug fixes !!! ### 3/5 — Stopped working *2017-06-04, version 4.1* Have been trying to us for a week May 31—Jun 4 stopped working ### 3/5 — EPA UV INDEX APP *2017-05-08, version 4.1* This app is the most user friendly and easy to read. However, it glitches almost every time I try to use it. It takes at least 6-7 tries to get it to load. Very disappointing. ### 1/5 — SO BAD! *2017-04-15, version 4.1* I wish I could rate it 0! Most of the times it doesn't even work! ## Most critical reviews (10 lowest-rated) ### 1/5 — No longer working *2026-03-01, version 7.0.0* No longer able to use this app. It will not post the current UV or hourly UV. ### 1/5 — Stopped working *2022-08-24, version 5.1* This a 5 star app and brilliant for UV (and once u know how to use it, can accurately know the weather 5 days in advance much better than any 5 day forecast). That said, it stopped working 3 days ago and doesn’t seem to be coming back. ### 1/5 — Dumb *2020-11-09, version 5.1* Your weather app gives you the same info ### 1/5 — No incentives for this app to work *2020-07-30, version 5.1* Clearly no one cares to update or make this app functional if it’s not for money. Total garbage, doesn’t even works 95% of the times. ### 1/5 — Not Working *2019-04-14, version 4.1* App Dead? ### 1/5 — Totally functionless *2017-11-25, version 4.1* Nothing is working. Totally functionless right now and has been for weeks!?!? Is this a dead app? Is there even an administrator for it. Use to love this app. Used it daily for years. Now, completely BROKEN! ### 1/5 — Just a blank screen *2017-07-07, version 4.1* Usually just loads a blank page. Please update! ### 1/5 — Doesn't work *2017-06-29, version 4.1* PLEASE UPDATE ### 1/5 — Does not load data *2017-06-01, version 4.1* Does not load data ### 1/5 — Disappointing *2017-05-26, version 4.1* App won't even load, reinstalled etc. what a disappointment. ## Most praised reviews (10 highest-rated) ### 5/5 — It does well what I need it to do *2022-09-15, version 5.1* I have had skin cancer so I now take extra precautions by checking what the projected UV risk will be for the day and prepare myself. It does everything I need. Thanks, EPA! ### 5/5 — Please update! *2020-08-19, version 5.1* Please update this for iOS 13/14! Thank you! ### 5/5 — Well designed *2019-11-29, version 5.1* App does exactly as described without annoying advertisements. Plus the data is exactly the data all weather services pull from but the gov’t has it first. So I don’t have to wait for accurate results. Well done ### 5/5 — Updated Review! *2019-05-27, version 5.0* I love this app but it hasn’t been working for a couple months now. When I type in my zip code, nothing shows up. The auto locate option has never worked for me. Please upgrade/fix this app! Update: this app has actually been working since the most recent update. Thank you! ### 5/5 — Awesome app *2015-07-31, version 4.1* Perfect for people who are very sensitive to the sun :) ### 5/5 — Perfect UV index app *2015-03-18, version 4.1* It offers everything you could need. Ad free, too. ### 5/5 — works nicely *2015-03-05, version 4.1* Thanks for fixing the GPS. I am photosensitive, so I appreciate that this app tells me when it is safe to go outdoors. ### 5/5 — Very handy *2015-02-09, version 3.0* Thanks for providing this ### 5/5 — Useful app! *2015-01-06, version 3.0* This is exactly why I appreciate this federal agency. They put useful information into the public's hands! ### 5/5 — Great app! *2014-12-20, version 3.0* Easy to use and great way to stay safe in the sun --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
