, Fullstory, and many more will give you insights, but be sure to take advantage of the options they provide to obfuscate personally identifiable information. Everything from the color of a button, to the image you chose, to the copy you wrote can have an effect on potential new users dropping off. An experienced designer should be able to quickly help you fix problem areas with better design and get more people all the way from your site to into your app.
