At one point, we offered an App Store program for iOS devices. However, we found that a web-based version of the app run significantly better, offered more flexibility regarding functionality we could include, and took less time to develop.

You can access it by pointing your smartphone or tablet to http://wplan.me (or http://m.worshipplannig.com). You can also read more abou the mobile site on our blog.
