NesiVar? — Know the truth about a car before you buy
NesiVar? is an OBD-II analysis app built to help you make the right decision when buying a used car. It reads the real data from the car's brain (ECU), interprets it with AI, and gives you a clear report. Instead of trusting the dealer's or seller's word, you look at the car's own data.
What is NesiVar?
NesiVar? is an independent pre-purchase inspection tool for used cars. Using a Vgate iCar Pro V2.1 BLE adapter, it connects to the car's OBD-II port, reads engine, fuel, exhaust and sensor data, and turns it into an easy-to-understand report with AI. If you don't have an adapter, there is also a pre-evaluation mode where you simply enter the make, model and year to see the known chronic issues specific to that vehicle.
