Autocast.The digital platform
for car enthusiasts.
Document your vehicle’s story, record drives and track sessions from your car’s ECU, then share, compare and discuss them with other members.
- A digital logbook for every car in your garage
- Drives, track sessions, virtual dyno runs and health checks
- Reference data and analytics for thousands of models
Built on real data
A catalog of the world's cars and circuits, ready before you record your first drive.
Start recording in three steps
No adapter yet? The website on its own keeps your garage and logbook, and lets you browse activities, models and other members’ cars.
Step 1:The iPhone app
Autocast for iPhone, on iOS 26.0 or later.
Step 2:An OBD2 Bluetooth adapter
A Bluetooth LE adapter that plugs into your car’s diagnostic port.
Step 3:Drive
Most petrol cars from 1996 onwards. The app records while you drive.
Four programs. Pick one and drive.
Nothing to set up. Each program knows what to read from your car, how often, and what to make of it afterwards. Choose one in the app, start the engine and go.
- Drive
Every sensor your car has, read for you
Drive finds the sensors your car supports and reads them all in turn: route, speeds, engine, temperatures, fuel, your pedals and the forces your iPhone feels. Afterwards you get the map, a replay and every figure through the trip, and over months a record that shows a change before it becomes a problem.
- Track Session
Laps timed, without a timer
Track Session recognises the circuit from its track database and splits your session into laps and sectors, with your best lap picked out. Each corner is read many times a second.
- Virtual Dyno
Your power curve, no rollers
Make two or three full-throttle pulls and Virtual Dyno draws power and torque, corrected to standard air. Spoiled pulls are left out on their own; compare before and after a change.
- Health Check
A plain verdict on your car's health
Health Check asks the engine computer for its fault codes, self-tests and the distance since codes were cleared, and gives each a verdict you can read. Worth doing after a warning light, and before you buy a used car.
Know your car better
Every drive you record becomes data you can read. Performance, trends and comparisons, with you deciding who sees them.
Track your car’s performance
Monitor your car’s performance data such as temperature envelopes, power, torque and acceleration, braking performance, driver inputs and fuel economy.
Easy to use analytics
With support for thousands of cars built in, Autocast works without any complex setup, using intelligent modules that record data elements dynamically based on their rate of change.
ECU data + phone sensors
Autocast blends the iPhone’s motion sensors with the car’s ECU data such as temperatures, driver inputs and engine data to deliver unique insight into your car’s performance and your own driving behaviour.
Comparative analytics
Analyse and explore changes in your car’s performance over time, compare your car’s data to other cars of the same make and model, or to other cars based on similar power, weight, or engine attributes.
Secure by design
You choose who sees your profile, vehicles and activities: everyone, just your friends, or only you. Your routes hide where you start and finish, and photos are stripped of location data when you upload them.
Identify issues earlier
Autocast’s trend analysis and comparative analysis can identify potential issues with a vehicle before they become critical problems. Autocast can tell you if a car you are test-driving performs like it should. Or if your pride and joy still passes muster compared to its peers.
