Octopus Energy Watchdog is a third-party app designed specifically for Octopus Energy customers in the UK. This app is a valuable tool for customers on the Agile tariff, allowing them to easily monitor their energy tariffs and make informed decisions about their energy usage.

The app features an intuitive and easy-to-read chart that allows users to scroll through and identify the best times to perform energy-intensive activities, such as doing laundry or charging an electric vehicle. With this information readily available, users can optimize their energy consumption and reduce costs.

Additionally, Octopus Energy Watchdog provides a rolling 30-day usage overview for households, eliminating the need to wait for monthly bills. This feature empowers users to make day-to-day decisions that align with their energy goals and ultimately save money. Users can also zoom in on individual days to compare their usage against historical tariffs.

It's worth noting that the developer of Octopus Energy Watchdog, Massimo Sanna, is not affiliated with Octopus Energy. The app is provided as-is, and user login details are neither sent nor stored on the device. The necessary API keys and parameters will be securely stored within the app, or users have the option to manually enter their login details for added privacy.
