However stopped working a week ago and data no longer available. ### 4/5 — almost perfect *2022-08-26, version 1.11.0* does one thing really well one “nice to have”: it would be great if the total would collapse or scroll up when scrolling up the source list, to fit more entries on the display great app! ### 4/5 — Archived data *2021-09-30, version 1.9.2* Great APP but would be a fantastic one if archived data could be accessed ### 4/5 — Engaging and thought-provoking *2017-05-06, version 1.6* A simple app for observing the ever-changing landscape of UK electricity generation/supply. In schools, pupils respond very well to the 'live' data and can see that recent changes, such as increased solar and offshore wind, frequently provide substantial chunks of our power needs. I look forward to seeing the App keep up with change, such as the new inter-connectors with Norway and France. ### 4/5 — No landscape mode on iPad *2014-11-07, version 1.5.1* Display does not rotate on iPad - display corruption is fixed in this release, but app is locked to portrait mode. Works properly on iPhone. Otherwise excellent - really useful app with very clear display. ### 5/5 — Really like it *2014-07-06, version 1.4* I think the app is really good but I also agree with nathanjm in that I would like to see solar listed too rather than just other. ### 4/5 — Solar? *2014-04-04, version 1.4* It would be good to see what proportion solar contributes to the energy picture. ### 5/5 — Great app *2014-03-23, version 1.4* This is fantastic! It combines two websites I've been monitoring in one easy place Clear traffic light system helps understand it you should run your washing machine/dishwasher or defer it Could have more data and graphs but that's being picky really ### 5/5 — Great app *2013-04-03, version 1.3* Great app, excellent interface. Has the potential to expand in the future with further electricity data. Keep up the good work! ### 4/5 — Nice app *2013-02-18, version 1.2* Would be nice to see how each individual energy source changed since the last update, i.e. if the percentage increased or decreased similar to how stock quotes display a up green arrow or down red arrow with the difference in percentages. ## Most critical reviews (10 lowest-rated) ### 1/5 — Stopped working *2021-07-26, version 1.9.1* This app has stopped updating over the last few days, so right now is useless. 26/7/2021 ### 1/5 — Not working following last update *2018-09-26, version 1.7.1* Excellent app but update to 1.7.1 now doesn’t work ### 1/5 — Bad app *2016-05-12, version 1.5.5* Wasn't a very fun/interesting game ### 2/5 — App no longer updating? *2023-03-21, version 1.11.0* Was a great app but seems to have stopped updating? ### 2/5 — Unusable in dark mode *2021-02-13, version 1.9.0* In dark mode I can’t read anything ### 3/5 — Doesn’t show graph *2022-08-13, version 1.11.0* Gives nice snapshot but no graph over time. ### 3/5 — Can’t see the graphs *2022-08-08, version 1.11.0* This app looks brilliant but I can only see the first page. How do you get onto the line and bar charts? Thanks. ### 3/5 — Missing !! *2012-06-29, version 1.2* You have Gas, Coal, Nuclear, Hydro & Wind but nothing about, the growing, Solar!! That aside, quite a good Ap. ### 3/5 — Interconnectors? *2011-02-27, version 1.2* Where are the French, Irish and Dutch interconnectors? ### 4/5 — Good *2025-08-29, version 1.16.0* Good app. Like the landscape mode with toggles for each type of energy source. Would be good to have demand displayed as well. ## Most praised reviews (10 highest-rated) ### 5/5 — Really useful *2024-06-05, version 1.15.0* I use this to plan my discretionary electricity use such as washing machine. Also interesting to see the constantly hanging mix of power generation. Very grateful to the app developers for what they have done. ### 5/5 — Great UK grid carbon intensity in real time *2021-10-26, version 1.9.2* This is great app. I rely upon it to decide when to run my appliances and large electrical loads. So that I limit my impact somewhat. ### 5/5 — Great app *2021-02-14, version 1.9.0* Excellent app. Simple and clear. Fascinating to look at in windy / sunny / cold days etc. Also good for seeing when to put the dishwasher on to minimise carbon. ### 5/5 — Get it *2020-10-15, version 1.8.1* I’ve had loads of interest when I’ve shared how much we’re getting from sustainable sources. ### 5/5 — Fascinating Data. Great Presentation *2020-04-12, version 1.8.1* and a reliable, functional app. Highly recommended. Thank you! ### 5/5 — Brilliant app *2019-08-22, version 1.8.1* Brings home what our energy sources are ### 5/5 — Awesome *2018-11-01, version 1.7.1* Awesome app with relevant information! Love to see how the uk is generating its energy and this app helps me do that easily! 😊 #CleanEnergy ### 5/5 — Excellent *2017-09-26, version 1.6* Really interesting data. Useful for deciding when it’s best to use energy intensive appliances. ### 5/5 — Great summary of energy generation *2017-04-15, version 1.6* As someone who takes an interest in low carbon electricity generation, this app is a great way to get a quick insight into what's currently powering the UK grid. Love the new solar estimate - keep up the great work! ### 5/5 — The more you know! *2016-12-05, version 1.5.5* Awesome app that displays the current energy input source for the U.K. grid. We need more of this. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
