## Description

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