Is the Web App really free for the Beta period?

Yep, that's right. 

The web app is free for all new, current and old customers so even if your web app trial has ended, we've reactivated it for you which means you can continue to use PredictHQ until the end of our Beta period for free. 

When our Beta period is coming to an end, we'll give you a heads up 30 days beforehand. If by the end of our Beta period you decide you wish to continue using PredictHQ, you'll simply need to upgrade to a paid plan.
