| Topic | Viametry | TeslaMate | Tessie | Phone GPS apps |

| Setup | Sign in with your Tesla account; nothing to install | Docker on an always-on machine, with Tesla API tokens you generate yourself | Install the app and sign in with your Tesla account | Install the app and carry the phone on every drive |
| Access to the car | Read-only | Read-only: it logs data | Reads data and controls the car, for example locks and climate | None: the phone records the route |
| Charging costs | Charging costs: Supercharger bills from Tesla, your home tariff, public chargers by saved price or the amount from your bill | Charge cost tracking | Charging history | Not recorded |
| Business logbook | Business plan: profiles for Czechia, Germany, Austria, the Netherlands, Poland and Slovakia; PDF, CSV and Excel with change history | Not built in; the data stays in your own database | Tag drives, for example as business, and export them to CSV | Their main purpose; formats depend on the app |
| Drivers and fleets | Owner, manager and driver roles, private mode, reimbursements | Several cars per Tesla account | For drivers and fleet managers, according to Tessie | One log per phone, so per driver |
