Wisepops Popup & Notifications , 68 reseñas
This is a great app. But, very expensive when you want to start unlocking some of the "advanced features".
Highly featured and easy to use. An excellent app. BUT it can work out very expensive. This is because It is priced on how many page views your site gets, NOT how many times your pop ups appear. If you have a lot of pop up 'events' then it could be right for you. If you only need to display a few pop ups, you may want to look at an app with a different pricing structure.
good app, little glitchy but good service
