Features
Everything you need to pay less — nothing you don’t
Today and tomorrow, at a glance
A clear bar chart for the whole day, hour by hour or in 15-minute slots. Cheap hours in teal, expensive ones in orange, and the current price with its level, always with an icon and a word — not just a colour.
The best 1, 2 or 3 hours, found for you
Pick how long you need and Wattime finds the cheapest window today or tomorrow, with how much less you pay than right now. Tap “Remind me” and forget about it.
Your price, wherever you look
The small widget is free and works on the Home Screen, in StandBy and in CarPlay. With Pro, add Lock Screen widgets and medium and large widgets with today’s and tomorrow’s chart.
Plan the washing machine — or your EV
Add your appliances once, with how long they run and their power. Wattime tells you when to start each one, what it costs and how much you save. For your electric car, it picks the cheapest hours before you leave.
France: your Tempo colour, today and tomorrow
Compatible with the Tempo option of EDF: see today’s colour, tomorrow’s as soon as it’s announced, and how many blue, white and red days are left. Spot prices are there too.
Never miss the cheap hour

FAQ
Questions, answered
Where do the prices come from?
From official and public sources: Red Eléctrica de España and OMIE for Spain and Portugal, Energy-Charts.info for central Europe, Energinet, elprisetjustnu.se, hvakosterstrommen.no and Finnish price services for the Nordics, Octopus Energy for Agile and RTE’s Tempo colour for France. The full list is on the support page.
Do the prices include taxes?
In Spain, the PVPC can be shown with electricity tax and VAT (IGIC in the Canaries, IPSI in Ceuta and Melilla). Octopus Agile prices include VAT and Tempo prices include taxes. Elsewhere you see the wholesale market price plus VAT; your supplier adds its margin and network fees. Standing charges are never included.
Which tariffs does it support?
Spain’s PVPC (2.0TD) and the wholesale price for indexed tariffs, Octopus Agile in the UK, the Tempo option in France, and the day-ahead spot price in every other country. If your contract follows the hourly market, Wattime is for you.
Does it work offline?
Yes. Wattime keeps the last prices it downloaded, so today’s and tomorrow’s prices, widgets and alerts keep working without a connection. It shows when they were last updated.
What about my privacy?
Wattime collects no personal data: no account, no analytics, no ads and no tracking, and it never asks for your location. Your settings, appliances and alerts stay on your iPhone. Read the privacy policy.
Is it really free?
Yes. Today’s and tomorrow’s prices, the chart, the best window, the small widget and the daily alert are free forever, with no ads. Pro adds more widgets, the planner, alarms, history and Siri.
