This is a start

I appreciate the live UVI readings. Please provide a widget so that the app doesn’t need to be opened every time!

Great to hear you are enjoying the app. Thanks so much for the suggestion — we’ve logged this as a feature request. Widgets are common request and we’ll share your feedback with the product team.

VERY INACCURATE, DON’T USE

App reads 2.5 UV when other sources claim it’s 11. This app is actually a danger to use. At other times it has frequently listed the wrong UV

No widgets in 2026?

This app looks good and trustworthy but I deleted it basically straight away because it has no widget functionality. Hopefully Cancer Council gets with the times and adds this soon - I’m sure they’d see much higher use of this app and less negative reviews if they did. Basic low level functions that don’t match the vast majority of what else is out there just doesn’t really cut it in the age of technology.

Thank you for reaching out. We have shared requests for a widget with our product team. We appreciate you taking the time to provide feedback.

Worried by this app

The openness about data sources is very refreshing, but I’m not happy with the way uv data is presented. I’m currently in the south of Gran Canaria, and whilst the UV forecast looks fine, the weather forecast for the days ahead is well off. It turns out the nearest data source being used is for Las Palmas in the North which has a different climate from where I am. The app however gives a forecast supposedly for the exact part of town I’m in. This data inaccuracy about the weather has reduced my confidence in the UV data too.
