SmartRules depends entirely on SmartThings infrastructure to build and run your rules. Due to changes in that infrastructure, we have been unable to release any updates to the existing implementation of SmartRules. Recently, the amount of problems caused by the SmartThings infrastructure have caused us to make the decision to pull SmartRules from the App Store until we are able to complete a new version of the app that will utilize the new interfaces with SmartThings and be better equipped to handle problems with the infrastructure.

Existing users will be able to continue using SmartRules as usual, as long as SmartThings continues to support that previous generation infrastructure.
