The K-Rain BL app allows you to control your K-Rain BL-KR Battery Powered Timer, BL-24 Indoor Irrigation Timer, and TC-KR Hose End Timer using Bluetooth Smart Technology. This means you can use it even if you don't have an internet connection or your phone is out of range. The app is compatible with both iPhone and iPad and works with your phone or tablet's built-in Bluetooth Smart capability. You will only need to download the app once. You can then use it on your phone or tablet anytime you want.

The app is designed to make it easy for you to control all three of the K-Rain devices using a single app. It will also allow you to set multiple watering schedules for each of the devices. You can also set different zones for each of the devices so you can have more control over the devices.
