Whisker is a free app developed by Automated Pet Care Products Inc. for iPhone users. This app allows you to remotely monitor and control your WiFi-enabled Litter-Robot unit(s) and Feeder-Robot unit(s) all in one place. With Whisker, you can keep track of your cat's litter box usage and your pet's feeding habits, giving you full control of your Litter-Robot 3 Connect, Litter-Robot 4, and Feeder-Robot right from your phone.

The app provides several features for the Litter-Robot 3 Connect, Litter-Robot 4, and Feeder-Robot. For the Litter-Robot, you can view the waste drawer level, get real-time status updates, monitor your cat's litter box usage, and manage your Litter-Robot settings. For the Feeder-Robot, you can customize multiple feed schedules, see feeder status, get feeding insights, give your pet a snack, and connect multiple units. The app requires iOS 13.0 or later, camera permissions to scan QR code, and a 2.4GHz connection (5GHz not supported). Please note that robots will only connect to secure password-protected networks and will not connect to hidden networks.
