Full description

WattSave compares how much energy your trip would use as an EV vs a petrol/diesel vehicle — in real time. Drive as usual while the app estimates and displays side-by-side consumption and cost impact based on speed, acceleration, elevation changes, and vehicle parameters. It’s a practical way to understand the real energy profile of your route. REAL-TIME COMPARISON • EV energy estimate vs petrol/diesel equivalent • Live updates while driving • Route-aware behavior (accelerate, brake, climb, descend) COST INSIGHT • Enter local fuel and electricity prices • Compare trip cost between vehicle types • Understand potential savings with electric driving VEHICLE FLEXIBILITY • Pick from supported EV profiles • Add custom vehicle parameters (mass/aerodynamics) • Tune assumptions for more realistic comparisons TRIP METRICS • Distance and speed tracking • Elevation-aware estimation • Sensor-based motion input from your phone WHY USE WATTS APP • Make EV decisions with route-level data • Visualize hidden energy differences in daily driving • Useful for commuters, EV-curious users, and energy-conscious drivers If you’ve ever asked “How different would this trip be in an EV?”, WattSave gives you a clear, data-driven answer.
