WattSave: EV vs Gas Simulation

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.
