Frequently asked questions
Is WattSmart free?
Yes. WattSmart is free to download and use for checking today’s and tomorrow’s day-ahead electricity prices in hourly resolution. The free version includes ads.
Premium Unlock is optional and is purchased once, with no recurring subscription. It adds 15-minute resolution where available, tax and surcharge settings, national-currency support in applicable countries, and ad removal.
Which countries and market zones are supported?
WattSmart supports many European electricity market zones. Available countries, regions, and languages can be selected in the app settings.
Why do electricity prices change during the day?
WattSmart displays day-ahead electricity prices: market prices published in advance for each delivery interval. Depending on the market zone, prices are available in hourly intervals or, with Premium Unlock where supported, 15-minute intervals.
Are the prices shown the same as my final electricity bill?
Day-ahead prices are market prices. Your final bill may also include taxes, network charges, supplier fees, and other costs. Premium Unlock lets you add tax and surcharge settings to make the displayed price more relevant to your planning.
