As much as I agree with you the same thing is often said about weather apps. However the really accurate ones (e.g. Dark Sky) that can predict to the minute and give intensity are really useful. For example I was able to plan my lunch break using it yesterday so I was out of the office in the 30 mins of dry weather between rain showers. The the UV sensor you could probably work out what strength suncream you need and if people apply the correct strength maybe in the long term skin cancer rates will fall. Small change in behaviour due to better information, big improvement for society.
- joosters 12y ago(Thanks for highlighting Dark Sky, that looks like an interesting app!) Don't your arguments (and app recommendations) point against a UV measure as being useful? If you want to know whether or not to put on sunscreen now, for a day out, knowing the current UV strength is no use since the conditions will be different later. That's where weather prediction comes in and makes your one little watchband UV datapoint useless. Looking up at the sky and observing weather conditions will always be better than that, and better weather prediction will beat looking up at the sky.
- k-mcgrady 12y agoAh, very good point I didn't think of that. I suppose it could function as a warning system. You're go out in the morning and it's cloudy and suncream isn't required. As the day goes on the UV levels increase and your fitness band can warn you that you should think about applying suncream as the UV levels have increased.
