Read full description

Own the data. Know exactly what your EV costs - and what it saves on fuel. Volt is the essential tracker for electric vehicle owners: log every charge, track every trip, and see your real savings vs fuel every month. The home screen puts your monthly number front and center - not an estimate, but your actual figure based on your charging sessions, your vehicle, and current gas prices. YOUR SAVINGS VS FUEL Your monthly EV charging cost vs what you would spend on fuel in a comparable gas car. Updated automatically as you log charges and trips. This is the number EV owners love to share: "I saved $127 this month vs gas. Year to date: $680." CHARGE LOG (kWh + Charging Cost) Record every session - home Level 2, public DC fast charge, or free workplace charging. Track energy added (kWh), total charging cost, cost per kWh, battery state, and location. Monthly totals show what electricity actually costs you. Filter by home vs public vs free to spot patterns. TRIP TRACKER (mi/kWh) Log drives with distance, energy used (kWh), and efficiency in miles per kWh. Add temperature, HVAC use, highway percentage, and driving style to understand what factors affect your range. Real fuel cost per mile on every trip. BATTERY DEGRADATION TRACKER Is your battery losing range? Log your full-charge range readings monthly and track battery degradation against your car's original EPA rating. Volt shows your degradation curve and tells you whether it is within normal bounds - 10% loss at 30,000 miles is expected and completely normal. The tracker turns battery anxiety into battery confidence. HOME CHARGER EFFICIENCY Enter your home charger electricity rate or time-of-use (TOU) schedule. Volt calculates home charging cost automatically and shows your real cost per mile at home vs public charging. Pro users get the TOU Rate Optimizer to identify the cheapest charging windows - off-peak home charger scheduling can cut your electricity bill by 50-75%. CHARGING NETWORK REFERENCE Current rates for Tesla Supercharger, Electrify America, ChargePoint, EVgo, Blink, and more. Membership advice and free charging locations. FREE FEATURES INCLUDED - Up to 20 charge sessions per month - Up to 15 trips per month - Monthly savings vs fuel - Charging cost per kWh - Per-trip efficiency in mi/kWh - 3 months of charge history - Battery degradation tracker (6 checks) - Home charger rate calculator - Network reference VOLT PRO - UNLIMITED DATA - Unlimited charge and trip logging - Full charging history, no time limit - Efficiency Analytics by factor: temperature, speed, HVAC, elevation - AI EV Advisor - 30 Grok-powered queries per day - Total Cost of Ownership comparison vs fuel vehicles - TOU Rate Optimizer for home charger savings - Shareable Year Card for your annual EV stats - CSV Export for custom analysis - Custom App Icons - Full battery degradation chart For every electric car on the road - Tesla, Rivian, Hyundai Ioniq, Kia EV6, Ford Mustang Mach-E, Chevrolet Bolt, BMW i-series, VW ID.4, Polestar, Lucid, Nissan Leaf, and more.
