Your apps will not be widely known or used if they are very expensive. Customers do not like to committo anything until they have a reason and just getting to know your store is not a good reason to pay for an app they might never use. We make free Shopify apps here at Expert Boys.
Although you will be offering your store apps for free you will be gaining a lot from them because of the in app purchases that will be made on that app. Allowing users free access to the store itself is the first and most important step. Even if a purchase is not made, in the end it served as an advertising tool. Now your brand has gotten to one more person that would think of you when they want products like what you are offering. Your free app from Expert Boys might just end up profiting you much more than those with paid apps.
All our shopify apps are up to standard and they will empower you to do more for your store. The solid engineering, high level of design and high standards are paramount for standing out in the crowd. Using the right apps for your store will allow you climb the ladder of greatness faster.
