Wattif

Wattif helps you understand exactly how much electricity your home devices use — and how much they cost you each month.

Add the appliances you have at home (from a built-in catalog of 40+ common devices, or fully custom ones), set how many hours you use them per day, and Wattif instantly calculates your kWh consumption, monthly cost in euros, and CO₂ footprint.

Got an electricity bill? Add it in three steps — period, kWh, and the cost breakdown — and Wattif shows you what portion of your money goes to actual energy versus fixed charges (transport, system costs, taxes). The "fixed costs %" insight tells you, in plain terms, how much room you actually have to save.

KEY FEATURES • Track every device: power (W), daily hours, kWh per day/month/year • Cost & CO₂ estimates with your own tariff and emission factor • Bill analysis: variable vs fixed cost breakdown • Discover section: bust common myths about energy use • Real-world comparisons: how many cappuccinos, LED hours, or washer cycles your consumption equals • Export your data to share or back up • Everything stays on your iPhone — no account, no cloud, no tracking

WHO IT'S FOR Anyone who wants to actually understand their electricity bill instead of just paying it. Pair it with the educational content to learn where saving actually matters (hint: lighting is not where most savings come from).
