Overall the smartphone app performed similar to that of the ET controllers and provides an alternative for users where an ET controller is not a viable option. One limitation of the app is the exclusion of site-specific rainfall. Another limitation is that the app is not directly connected to the automatic irrigation controller so the user must manually implement a schedule change at the controller. As was noted in this study, this is not always possible. Thus, some notifications for bypassing irrigation events due to predicted or measured rainfall may not be implemented in the irrigation schedule by the user.
