App Description
EV vs Gas Cost Calculator — compare energy use and trip cost in real time.
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
