A few years ago we discontinued support of our iOS mobile app and focused on building a responsive UI that works well across all different platforms. While this decision has allowed us to consolidate our engineering focus and speed up the delivery of features, we do recognize that an extra step is required to access Fantasy Postseason via a mobile browser.  However, there is indeed a way to add Fantasy Posteason to your mobile device home page, saving you a step.  Check out the following instructions based on your particular mobile device:

iOS devices (MacRumors)

Android devices (wikiHow)

Note that if you want direct access to a particular league for easy access to check scores, etc, we suggest short-cutting your postseason fantasy league's home page to the home page of your mobile device. That way, when you click on the FP icon, you'll be sent directly to your fantasy league's home page.
