Do you want to know exactly how quickly your car accelerates to 60 mph? Its no secret that manufacturer data is approximate and applies only to ideal conditions. To determine your current speed and make measurements from 0 to 60 mph, 60 to 120 mph, or the time it takes to cover a quarter-mile (¼ mile), the Test Drive app will help. No additional devices will be required since your smartphone already has the same accelerometer and GPS sensors. Thanks to these highly sensitive sensors in your iPhone and a unique algorithm, we have the ability to measure the cars acceleration time to the desired speed with high precision. App features include: * Acceleration to 60 mph * Acceleration from 60 to 120 mph * Acceleration to 50 mph * Acceleration from 50 to 70 mph * Time to cover ¼ mile * User-friendly interface * Regular updates and expanding functionality * Race results are automatically saved and can be shared with friends!
