UV-Index is a simple widget that displays the current UV-Index and it's daily maximum for any location. The widget makes use of GPS coordinates and retrieves the UV-Index using a web service provided by OpenUV Project (https://www.openuv.io). This API provides a convenient way to get the UV-Index including relevant corrections for ozone, cloud coverage and accurate altitude data.</p><p>.</p><p></p>
v1.2.3 Support for Venu and Vívoactive® 4 added</p><p>----</p><p>You can now check the UV-Index BEFORE you go outdoors. The position from your last outdoor activity with GPS is used to retrieve the UV-Index. To update position press START button (this invokes GPS). This is now the new default behaviour, to revert to old behaviour go to app settings and uncheck "Use last known position". Enjoy using UV-Index indoors!

Works well in Fenix 5s plus in the US. Would be nice to have a Pro version that includes a sunscreen timer, time till burn, uv alert, multiple locations, etc.

Thank you very much. Would it be possible to add the time until sun burn based on skin type? based on this formula https://www.openuv.io/kb/skin-types-safe-exposure-time-calculation

This is a super convenient way to check on just how much sunscreen I'll need :D

I have a Fenix 5, UV simply will not work and says ‘waiting for GPS. I installed it from the Connect IQ store and updated but it still will not work. Can someone from Garmin please contact me to assist with my problem please. My watch is Unit ID 3976798522 Sofware Version 14.2 (9954772). GPS: 4.40 (!) CIQ: 3.0.1 BLE/ANT/SNS: 6.90 WHR: 20.03.31

Used to work, and I loved it. One of my top 3. Five stars for sure. But for some months right now it doesn't work any more. Just keep "waiting for GPS..." unfortunately. :-(

Sorry to hear that. Can you pl contact me with more details (watch, firmware, GCM android or iOS). The widget is working fine for me and all my known testers, however some people/devices seems to have issues. Hope we can figure out what‘s wrong in your case.

It would be great to remember last location and update it only on manual request. Or to have option to choose how. Looking up gps every time takes away from otherwise great and useful widget.

Great App! If you could have an option to use "Last known position" and then a "update position" button that would be perfect!

I have a Garmin vivoactive 3 which is compatible with this app but for some reason I'm unable to use it because all it says is waiting for GPS then will just return to my watch face after a while

Hi. I have the Android version of that app purcased. Regarding this version for Garmin watch i guess is using the phone GPS instead the watch GPS. I tought that is acquiring the GPS position from the watch then use the data connection from the phone to get the UV index. But if not enable the phone GPS the index is never retrieved.

Nice app. The main think I'd add is to use last known position.

Tolle App, sowohl für die Garmin, als auch für`s Smartphone! Würde mich freuen, wenn auf der Garmin auch der Ozon Wert angezeigt werden könnte.

Thanks for your feedback. The ozone layer thichness is used by the app to calculate the UVI. It’s a major factor for the UVI and can cause changes by more than 20% from day to day with same weather and same location. However, this value has nothing to do with the ozon value measured at the eath surface In contrast to the ozon layer thickness I do not have high quality global data for ground level ozon.
Sorry, no statistics available yet.
