Know your electricity price.
Now with Apple Watch support: just lift your hand to know the price.
WattCat shows Nord Pool day-ahead electricity spot prices for Estonia, Latvia, Lithuania, and Finland in a clean, fast app. Check the current hour's price on the dashboard, see how the rest of the day looks on the hourly chart, and shift your laundry, charging, or heating to the cheapest hours.
TODAY AT A GLANCE
• The current hour's electricity price in cents per kWh
• A friendly trend mascot that tells you instantly whether prices are low, normal, or high — and rising, steady, or falling
• Today's minimum, maximum, and average price
• An hourly price chart, color-coded from cheap green to expensive red
PRICE HISTORY
• Browse historical price ranges to spot patterns across days, weeks, and months
• The same clear color-coded chart everywhere, so expensive hours are obvious at a glance
MADE FOR THE BALTICS AND FINLAND
• Markets: Estonia (EE), Latvia (LV), Lithuania (LT), and Finland (FI)
• Switch your market anytime in Settings
• Show prices with or without your market's VAT — one toggle, correct local VAT rate applied automatically
WHY SPOT PRICES MATTER
If you have an exchange-price (spot) electricity contract, the price you pay changes every hour. Day-ahead prices are published in advance, so a quick look at WattCat each evening or morning tells you exactly when tomorrow's cheap hours are. Running the dishwasher at 14:00 instead of 19:00 can cost several times less.
SIMPLE AND PRIVATE
• Sign up with just an email address — nothing else is collected
• No ads, no tracking
• Delete your account (and all data) anytime, right in the app
WattCat uses official Nord Pool day-ahead market data, processed and served by our own backend so the app stays quick and light on your battery.
