How many snapshot reports do I get with a free account?

You can run unlimited free, 100-tweet snapshot reports with your free account. All free snapshots will be saved to your My Snapshots archive by default for future access (though you can remove unwanted reports anytime). 

You can also purchase full reports (up to 1500 tweets) for $20 each or sign up for a subscription plan, which includes unlimited full snapshot reports at a low cost.
