Apple CEO Tim Cook delivers the keynote address at Apple's annual Worldwide Developers Conference at the Bill Graham Civic Auditorium in San Francisco, California, onJune 13, 2016.

A group of people that makes apps has banded together to ask Apple to allow more free trials and better revenue from the App Store.

The cadre calls itself the "The Developers Union," according to its website, and includes over 100 people as of Friday afternoon. The group doesn't have dues and says it's a "non-union union." Its main demand is allowing every app to offer users a free trial period "to show users their creation and establish value." Today, only subscription-based apps can offer a free trial.

In the future, the group may also ask for an increased share of App Store revenue.

Apple didn't immediately respond to a request for comment on the new group.

The website says it was inspired by the documentary, "App: The Human Story," which follows the stories of several app makers who decided to enter the app-making industry in the early days of the iPhone.

The union is forming ahead of Apple's annual developer conference, WWDC, which runs from June 4 to June 8 in San Jose, California. That event is where the company usually reveals new software features coming over the next year.
