Octopus Watch is the easiest tool to manage the (smart) tariffs provided by Octopus Energy in the UK. Octopus Watch is a paymium app for iOS offering both a standard version as a one-time purchase, and an optional subscription with additional features. Ready to supercharge your savings? Save significantly on your electricity bill, regardless of whether you're on Agile, Go, Cosy, Flux, Tracker, or any fixed tariffs (basic or eco 7). Thinking of joining Agile? Log into the app with just your postcode and check out local rates. If you want to see your consumption history, you'll need an Octopus Energy account and an active smart meter. Please note that support for Intelligent and Intelligent Go is currently limited, with only default off-peak times available.

What's new in 5.4.0: • fix: energy reports were broken due to a bug in iOS 26.2 • new: added Octopus Snug as an unsupported tariff (same issues as Intelligent) What's new in 5.4.0: • fix: minor UI updates for iOS 26 and iPadOS 26 What's new in 5.4.0: • new: complete the transition to the new Nix 5 prediction engine • fix: update the legend on energy reports to correctly show the label for export rate What's new in 5.3.2: • fix: update 5.3.1 caused data to be loaded slowly on first login due to the extra checks. This is now resolved and data on first login loads again at the normal speed. What's new in 5.3.1: • new: The app can in many more cases get your data, even if the Octopus Energy API experiences issues. Octopus Energy uses two APIs. The app can now fall back on the second API when the first API becomes unavailable for some of its tasks. • fix: in some cases the app was unable to retrieve historic data after a while. This update introduces a fix to this problem. What's new in 5.3.0: • fix: re-enable long press on home mini card for energy tracking • fix: prevent rates chart from extending into the title (still going "off the charts") • new: date on carbon detail page • new: chart lock in day details for easy day-to-day comparison • new: custom home mini/live data split value for Agile users What's new in 5.2.0: • fix: comparison skipped a day due to DST bug • new: while travelling the app will continue to show UK time zone What's new in 5.1.4: • fix: up and down scrolling on the day details did not work in some areas of the screen What's new in 5.1.3: • new: optimised layout for iPadOS 18 What's new in 5.1.2: • new: add tinted icon variant for iOS 18 What's new in 5.1.1: • fix: correct unit on Home Mini live card (kW, not kWh) • fix: in some cases the wrong rate was used for some fixed/dumb tariffs What's new in 5.1.0: • new: (subscription) support for Home Mini. • fix: various optimisations. What's new in 5.0.6: • fix: predictions still, in some cases, disappeared at 4PM. More firm instructions have been passed along to stay in place. • fix/new: notifications are using a new backend, which again allows rate-specific notifications. • new: optimisations to how carbon data is retrieved. • new: more aggressive checks for new history data. 5.0.5: internal release What's new in 5.0.4: • fix: predictions could briefly disappear around 4PM, they are now kindly requested to stay where we can clearly see them What's new in 5.0.3: • fix: predictions were updated at least every 15 hours instead of every 15 minutes in 5.0.2 resulting in weird behaviour • new: improved support for onboarding tariffs that are often unique to one or a handful of Octopus Energy customers • new: internal optimisations to improve the code and performance What's new in 5.0.2: • new: see export in peak / off peak for Flux • new: (subscription) get weather data in CSV export • fix: correctly show history on Apple Watch • fix: correctly show/hide rate table legend when changing size of table Version 5 is a major update bringing a speedier app with some great new features: • 5.0.1: hotfix to correctly display export tariff label • new one-tap tariff comparison • new micro metrics to easily see trends in your data • (subscription) full year electricity data and energy reports • (subscription) tracker rate predictions And, of course, various other minor improvements throughout!
