need this for my edge 1040!

Jordi CP
2022年10月5日 | V1.3.4 版

I need this widget in my Edge 1040!

2022年8月25日 | V1.3.4 版

The widget was functioning fine, but since some time it does not work anymore. It only shows IQ! In the middle of the watch face. Any idea how to fix this?

2022年8月25日, laufschnauff

Most likely a connection problem and not an issue of the widget itself. Ensure that your mobile and watch are connected via Garmin Connect Mobile App while retrieving the UV-Index

2022年7月13日 | V1.3.4 版

Sometimes works others not, most of the time seems to show the correct index but there's time on the day that doesn't make sense what is shown (either higher index or lower, cross checked with few UV Index sources)

2022年8月25日, laufschnauff

This is most likely due to the weather forecast data. The current UV-Index in my widget is corrected with the cloud coverage (in %) retrieved from openweather. You should compare the UVmax value to what weather services publish as this is the clear sky maximum for the day. Use this value (and your own judgement) to be on the save side!

doesn't work for forerunner 235...

2022年5月8日 | V1.3.4 版

Super! Schön wäre, wenn man beim Durchscrollen ohne Wartezeit den letzten UV Index sehen würde, auch ohne Bluetoothverbindung zum Smartphone. Zumindest den prognostizierten Tageshöchstwet.

2022年5月10日, laufschnauff

If your watch supports „widget glances“ and you switch this feature on you have exactly this behavior.

2022年4月21日 | V1.3.3 版

@Tomkin, it does work. Just contact the developer

2022年3月25日 | V1.3.2 版

Works fine for me on my fenix 7x

2022年3月11日 | V1.3.2 版

Awful does not work

Thomas Genzel
2022年2月24日 | V1.3.1 版

Ob man es wirklich braucht? Gute Frage! Aber es funktioniert und stimmt auch mit den Wetterdaten überein. Sicherlich gut, wenn man unterwegs UV-Schutz erneuern will. Gute Arbeit!!! (Fenix 6X Pro)

2022年2月15日 | V1.3.1 版

Like it. Simple, always working great.

Jan Vodička
2021年11月5日 | V1.3.1 版

Perfect! Simpl and working well. Thank you.

Daniel F
2021年7月29日 | V1.3.0 版

An excellent widget. Very well made, works well and doesn't seem to negatively affect my watch battery life. Recommended.

2021年7月26日 | V1.2.9 版

Simple and efficient

2021年7月22日 | V1.2.9 版

Application très utile, qui permet de réagir afin de protéger sa peau des dégâts causés par le soleil, vraiment très bien !!

Daniel F
2021年7月21日 | V1.2.9 版

A simple, accurate UV indexing tool. Brilliant :)

2021年7月15日 | v1.2.8 版

Does not work on Venu after update.

2021年7月15日, laufschnauff

Works perfect in simulator. If you expect help, kindly contact me with more details instead of leaving an unspecific 1-star-review. If you want me to respond, please also ensure you add your e-mail when clicking the "Contact Developer" link.

Simply does not work on vivoactive 4 after the update

2021年7月12日, laufschnauff

Sorry to hear that. Can you pl contact me with more details. I can't see any issue with CIQ Simulator for vivoactive 4.

2021年6月28日 | v1.2.7 版

Very simple app, works even without phone location turned ON. I'd love if there was a datafield that could be dropped into workout screens.

2021年6月19日 | v1.2.7 版

Stopped working on Fenix 3... Loved it, but now relying on Garmin app... Would love to know how to fix

2021年7月7日, laufschnauff

Sorry, V1.2.7 broke support for Fenix3, please upgrade to V1.2.8

Mr. M.
2021年4月28日 | v1.2.6 版

I really don't understand why my Fenix 6S Pro shows 3.9 UV-index and 12.8 UV-index Max while my other watch Vivoactive 4 shows 4.3 UV-index and 5.0 UV-index Max. Those values can't be trusted! What's wrong with this widget?!

2021年6月22日, laufschnauff

Issue should be fixed with V1.2.7

2021年2月8日 | v1.2.6 版

Probably it does what is says but it is laggy and boring. At least some minimum design is needed.

2020年12月10日 | v1.2.6 版

Also this widget uses too much battery, please also fix.

2020年12月4日 | v1.2.6 版

Everytime you use the workout applications or connect to PC, the widget has to find GPS again, please update a fix for this, so that the cache doesn't get cleared unless you manually update to new GPS location.

Luca Giovagnoli
2020年11月25日 | v1.2.6 版

Seems great. Would you mind adding details on whether this app connects to the internet in the background during activities? I’d like a setting only to retrieve the UV index manually to save on battery

2021年1月31日, laufschnauff

There is no background activity. Internet access is done only once (and manually) when you launch the widget. Thus impact on battery is zero when you don’t open the widget.
