This app helps make sense of election polling. Use it to compare precision between polls, or to calculate the sample size needed to produce a certain margin of error.
It will also perform a hypothesis test and calculate a p value, given the null hypothesis that neither candidate is ahead. In other words, it will tell you how much confidence you should have in polling results.
