For example, if you break down, Dash can give you a report on what's wrong and how much it will probably cost to fix; if you're in a crash, Dash can automatically notify close friends and family. Like Dash, Automatic offers both a smartphone app and a physical sensor, and it has an almost identical set of features. In addition, it includes extras like a dedicated response team to help if you have an accident, and real-time tracking of your driving and parking. The number of extras you receive depends on the plan you buy. The Automatic Lite plan has route tracking and engine diagnostics, and it will set you back a one-time fee of $80; the Pro version comes with crash assistance and support for third-party extensions, and it costs $130. If you don't care for the comprehensive route tracking you get from Dash and Automatic, you can purchase similar services that concentrate less on tracking and more on diagnostics. Fixd charges $60 for a single sensor, which you can then pair with the free app (for iOS or Android ). After a certain number of miles, it will send you maintenance reminders, and it will also flag any issues the engine might be experiencing. OBD Auto Doctor works along similar lines, and it can run from a Windows or macOS computer as well as an iOS or Android device. Look up fuel consumption, diagnose engine problems, track your car's health, and more—you can try the app for free, but to see all the data you need to pay a one-time unlock fee of $18.
