Hey everyone! I built WattWise because I was shocked by my electricity bill and had no idea which appliances were costing me the most. WattWise gives you 15 free calculators that let you plug in your usage and see exactly what each appliance costs to run — daily, monthly, and yearly. It covers everything from AC and heating to pool pumps and EV chargers. No signups, no ads, just quick answers. Would love to hear what you think!
