How accurate it is I can not say because i used it only one day and im going to uninstall it after I write my feedback because the ads inside are way to invasive .if you want to check real quick the weather before you go you have to escape the huge amount of the ads wich pops out. Im ok with ads when i don't want to pay for an app but it has to be a reasonable amount and not invasive. Because it is faster to check on Google without being forced to deal with ads.
