Spot: point the phone at the iron
You are standing in front of a vehicle and nobody can tell you exactly what it is. Open Spot and photograph the VIN plate, the RC, or any badge you can read. The register does the rest: it reads what it can, matches it to a variant, and shows you the spec sheet for that exact vehicle.
It is at its best in a yard, at an auction viewing, or beside a vehicle somebody is selling you. Knowing the exact variant is the difference between comparing prices and guessing at them, because two vehicles with the same model name on the bonnet can be lakhs apart.
If the photograph is not readable it says so rather than guessing, and you can ask Ustad from the same screen with what you did manage to read.
