What's New

This update fixes the issue where programs were not saving correctly and saved programs were disappearing on the new, updated version that was released on March 9th, 2015. We are listening to what you have been telling us, and are working on other matters that have been brought to our attention as well.

Also, please note, while this update fixes the issue with saved timers not saving on the new updated version, it will not bring back any old programs you had saved from the old style app from 2012. ***If you have the old style app from 2012 and are updating from the very first time this year, please note this update will not bring over any saved programs you have built on the old version. Do not update without first writing down your programs so you can re-enter them in the new updated app***
