What each app does
One adapter. Three apps built for where you drive.
OBD2, DragStar, and TrackStar share the same adapter, then split into the job each drive needs.

Only on TracQi
Your car has three stories. TracQi tells all of them.
Most apps show you what is happening right now, then move on. TracQi keeps a history for each vehicle across diagnostics, performance, and efficiency, with CoDriver explaining what changed and why.

Diagnostics profile
Catch the dip before the light.
Every session gets a health score, so you can see problems building over time instead of finding out when the car breaks down.
- 0-100 health score rolling up DTCs, monitors and live signals
- DTC timeline of when faults appeared or cleared
- Advisory monitoring before issues escalate
Performance profile
Watch your power build.
Every pull gets saved to your performance profile, so you can see where you are making power and where you are losing it.
- G-force trend logged every drive
- MAF vs. acceleration-derived HP per gear
- Weather correlation on your numbers
Efficiency profile
Find the MPG you're leaving behind.
TracQi tracks fuel economy by tank and trip, so you can see which driving habits are costing you money.
- Efficiency score across MPG, consistency and trim
- Economy trends every tank and trip
- Live fuel insight, no flow sensor required
TracQi CoDriver - suggested next step
Observation - Long-term fuel trim is -5.9%, and an active P0130 oxygen sensor circuit code is influencing it. Next - inspect the oxygen sensor and its wiring before it drives downstream fuel-trim errors.
One ecosystem - every data point
Capture on the go. Analyze at your desk.
Add a vehicle once, and it shows up across every TracQi app and the web dashboard. Your sessions, profiles, and tunes stay synced across iOS, Android, and the browser.
Add a vehicle once. It's everywhere.
Start a run at the track, then open your laptop at home and pick up where you left off. Your data is already synced, so you do not have to export files or plug anything in.

Under the hood
We handle the hard parts.
TracQi turns raw data into vehicle telemetry and profiles you can actually use to get your car where you want it to be.
01 - CONFIGURE
It starts with your vehicle.
Auto-build your car from the OBD2 port or a VIN scan - one source of truth every data point attaches to.
02 - CAPTURE
Read and fuse, live.
OBD2 reads PIDs at up to 50 Hz while TrueNorth fuses GPS, IMU and OBD2 into clean motion data.
03 - ANALYZE
Profiles, built for you.
Logs land in your vehicle history and build Diagnostics, Performance and Efficiency profiles automatically.
