WattSmart.app
Smart energy tracking for cheaper electricity bills
Stop paying peak rates. WattSmart is the ultimate electricity price tracker for European consumers on dynamic tariffs. Monitor day-ahead market prices across countries and zones with 15-minute precision. Compare current rates against daily, weekly, monthly, and yearly averages (plus custom rates). Factor in local currencies, taxes, and supplier markups to find the cheapest hours instantly and lower your utility bills.
I’m the creator of WattSmart, and I’m super excited to share it with you all today!
Living in Europe with volatile energy markets, many of us shifted to dynamic/spot-price tariffs. However, I quickly realized that tracking when it's actually cheap to run a washing machine, charge an EV, or run a heat pump was way more complicated than it should be. Most tools were either clunky or didn't show the full picture.
That’s why I built WattSmart — to make energy price tracking simple, accurate, and actionable.
Key features built into it:
High-Precision Tracking: Hourly and 15-minute price resolution across European countries and market zones.
Contextual Insights: Compare current prices against your custom rate, as well as last week, last month, last year, or YTD averages.
Real Costs: Includes local currencies, taxes, and supplier markup customizations so you see the closest price to what you actually pay.
🎁 Special for the PH Community: Drop a comment below before Dec 31, 2026, and I’ll send you a promo code for free lifetime access with all premium features and no ads!
I’d be super grateful for your honest feedback, reviews, or a shoutout on social media. Every bit of input helps improve the app!
To everyone using dynamic tariffs or smart home tech: How do you currently manage your high-energy devices during peak hours?
