@johntheoak The business model is "freemium". The advanced functionality in the app (customizations and manufacturer-specific diagnostics) is paid, via an in-app purchase.
Carista is a mobile app that lets you customize your in-car experience to your liking. You can also check your vehicle for problems, as well as clear any fault codes. Carista is compatible with standard (i.e. inexpensive) OBD adapters that plug into your vehicle's diagnostic port. Unlock your car's potential! No more paying dealers an hour's rate for 2min worth of work!
