About this app

Octopus Watch is the easiest tool to track and stay on top of smart tariffs provided by Octopus Energy in the UK. Octopus Watch is a paymium app for iPhone, iPad, and Apple Watch offering both a standard version and an optional subscription-only version.

Ready to supercharge your savings?

Use the app to save big on your electricity bill, whether you are on Agile, Go, Go Faster, or Tesla tariffs. To use Octopus Watch and receive up-to-date Agile prices you only need a UK mainland postcode. For tracking of other smart tariffs (Go, Go Faster, Tesla) you need to have an Octopus Energy account. To get access to your historic usage you need to have an Octopus Energy account and an active smart meter.

Octopus Watch offers full support for Agile, Go, Go Faster and Tesla import, as well as full support for Agile, SEG, fixed, and Tesla export. Octopus Watch does NOT support the Octopus Tracker tariff or any Eco 7 tariffs. Octopus Watch unofficially supports most fixed tariffs as long as you have an active smart meter.

The standard version gives you all the tools you need to track and stay on top of smart tariffs:
• Immediately see the current price (also on Apple Watch!).
• Instantly get the cheapest slot to run appliances, or charge an EV, and save big!
• The app adjusts to the smart tariff you are on (Agile, Go, Go Faster, Tesla).
• Easily set different appliance timers (start at, hours until start, hours until end).
• See all upcoming rates in an easy chart and table.
• Beautiful widget with current and upcoming prices.
• Get a notification as soon as the next day rates are available.
• See your historic day-by-day usage.
• Easily compare savings against standard tariff or Agile/Go (not available if you have an export meter).
• See how much you earned through export (only available with an export meter).
• Various options to change the app defaults to best suit your needs!
• Export cleaned data to CSV for easy use in other apps such as Microsoft® Excel®.

Want even more? A single subscription gets you access to these amazing features:
• Up to 48h rate predictions – better plan your usage and save more!
• Have an export meter? Also get export rate predictions for Agile export.
• Get an instant notification when next day prices drop below a desired threshold.
• See the best half-hour blocks to charge an EV.
• CO2 integration - see your environmental impact both now and in the past.
• See the CO2 fuel composition, both as regional or national, and adjusted to your usage.
• Get the best slot, either based on price or based on lowest CO2.
• Day details – see your exact usage along with numerous statistics on a day-by-day basis.
• Get half-hour details right in the app to micro-optimise your usage.
• Create easy to read single page energy reports for any desired range over the last 4 months.

Thanks to Family Sharing you can install the app on all devices within the same family. Install it on your iPhone for an easy pocket reference, run it from your iPad to see the beautiful rate graph and double column table, or see the current rate with a flick of your wrist with dozens of complications to choose from. The choice is yours! Octopus Watch also supports subscription sharing, so one subscription gives you access to all the extras on all the iPhones and iPads in your household.
