It does this very well. My wish list item would be to get longer term views of the same information. ### 5/5 — Ontario energy production app *2021-12-07, version 2.3.0* Really insightful as to what’s going on in real time with our energy production. Has caused me to re-evaluate actual value of very inconsistent solar production. ### 5/5 — Great app with good detail, only for Ontario however. *2021-04-02, version 2.3.0* Better than Electricity Map as it shows individual station output. ### 5/5 — Cool as hell *2020-08-07, version 2.3.0* This thing is great if you have an interest in energy and industry. If not, well, it’s still amazing they can do this. ### 5/5 — Energy Science for Everyone *2020-04-15, version 2.3.0* This app has some really great features that make understanding the science behind the grid super simple and easy to understand. I appreciate the hourly updates on energy use and demand and it is really great to have all this info about energy production and the plants that create it in one place! ### 5/5 — Love this app *2020-03-07, version 2.3.0* I use this app at least once a day, and everytime I talk to elementary school and high school students about nuclear energy! ### 5/5 — Good app *2019-03-20, version 2.3.0* There is some missing info on various generating sites. Other generators are simply missing whether due to mothballing or some other unknown reason. ### 5/5 — Great app *2019-02-22, version 2.3.0* Very neat to see. It’s missing some information on some generating stations but it’s interesting. Remember it only accounts for transmission connected generation so lots of distribution connected wind, solar, cogen isn’t on here. But great app I use it lots. ### 5/5 — Amazing view of electrical grid! *2019-01-24, version 2.3.0* Truly great app that is an example for others with its clear, colourful, easy, and useful interface. Amazing to see so much great data instantly available so easily for free! Well done. Could use more data from solar generators, and would be great to see a “heat map” or similar view of power consumption... ### 5/5 — Clean and reliable app *2019-01-17, version 2.3.0* By far the best way to see the Ontario grid hour by hour. Provides detailed information on generation by plant. ### 5/5 — Awesome app! *2018-12-22, version 2.3.0* Love the updated version of Gridwatch. Very informative. ### 5/5 — Great app to toot the horn for a clean grid! *2018-12-19, version 2.3.0* I absolutely love this app and reference it on my News show on the local radio station that deals with energy and space. Ontario consistently rates as a clean energy Champion according to ElectricityMap.org This is an excellent tool to educate people on clean energy solutions ### 5/5 — Resource/ demand app *2018-12-15, version 2.3.0* It is a good idea to use the IESO data to present almost the real-time generation by fuel type. Also, it provides the demand, tie flows and net import/export. I hope you keep updating this app with any generation retirement or a new generation in the market. ### 5/5 — Ease of use *2018-12-10, version 2.3.0* I love this app! So easy to use ! Beautiful simplicity & I love the colours ! I use it a lot & find it has so much info. that it helps me understand the whole picture of energy use in a way I can understand & relate to! ## Most critical reviews (10 lowest-rated) ### 1/5 — Disappointing *2019-11-13, version 2.3.0* Hasn’t been updated in almost a year. No dark mode. ### 2/5 — Doesn't update with new projects very often *2017-01-12, version 2.2.0* Local wind farm has been running for several months and it's not listed here?!? ### 4/5 — Well put together. *2024-05-11, version 2.3.0* The only thing I would like is the ability to search historical data by date. ### 4/5 — Nice app *2019-09-29, version 2.3.0* Really helps to understand our electricity supply grid. Shows how little power (relative to the total) is being generated by solar and wind. I have noticed that many smaller wind and solar farms are not being reported. This distorts the data - which is why I only give it 4 stars. The app developer says that their information source does not provide data from smaller facilities. ### 4/5 — Useful App to view the grid *2019-02-06, version 2.3.0* This is a great app to view and understand generation in Ontario. I use this for work but is excellent to help understanding of electricity generation. Would be good to save days ex peak vs off peak. ### 4/5 — Great App! *2019-01-12, version 2.3.0* Gives you a great insight into where your electricity is coming from and which ones produce the most carbon emissions. ### 4/5 — Useful app but would benefit from history search *2018-12-19, version 2.3.0* Gridwatch gives a quick summary for the current hour, but would benefit from a historical search feature to be able to go back in time. ### 4/5 — Needs iPhone X Update *2018-06-15, version 2.2.0* Great app, but there is a lot of wasted real estate on the iPhone X. ### 4/5 — If the app can provide MW date from each generator it will be much better. *2017-07-06, version 2.2.0* Great app. I like it. ### 4/5 — Great app! *2016-03-30, version 2.2.0* Very handy if your interested in climate and energy issues. ## Most praised reviews (10 highest-rated) ### 5/5 — Best Energy App *2026-05-02, version 2.3.0* Great resource for Ontario energy ### 5/5 — Good information *2025-11-05, version 2.3.0* Surprised to learn that the Ontario generation is usually more from gas than hydro. That is not what I want to see but I am grateful that this tool is available. ### 5/5 — Amazing app *2025-04-18, version 2.3.0* 🔥🔥🔥 ### 5/5 — Great app *2025-04-15, version 2.3.0* Great to show current use of Ontario's elec. generating assets ### 5/5 — Great app *2024-09-03, version 2.3.0* Love the insight ### 5/5 — Great app *2024-07-03, version 2.3.0* Would love to see a widget added in a future release ### 5/5 — Very informative *2024-03-17, version 2.3.0* I just enjoy seeing how much power is used at different times on different days in different seasons, and how it is being produced. ### 5/5 — Concise Detail *2023-08-10, version 2.3.0* Concisely provides information of the ongoing, daily status of the Ontario electricity status. ### 5/5 — Stop all the fake opinions *2023-06-01, version 2.3.0* This is real, factual, straight forward information. Wish there was more info like this. Number of new homes completed each day. Or amount of money spent by each level of government daily. Or the wait times for a vaiety of surgeries in different hospitals in ontario. ### 5/5 — Nice overview of how the power grid works! *2021-12-17, version 2.3.0* Im so happy I stubbled upon this app! I love the detail of where our power is coming and every location of the sources in Ontario. Doesn’t seem to have an update for the last 3 years but hope to get an option to see a history of the power usage for the day or week instead of just the past hour! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
