Car Performance & Community
A performance logbook for your car, recorded with your phone
Your car. Your runs. Your progress.
Draggo records a closed-course acceleration session with the phone you already own, tells you how good the recording was, keeps the car setup behind every run and, if you want, shares results with other owners. It is a logbook with a community, not official race timing and not a dyno.
What Draggo does
- Records an estimated 0–100 km/h time from detected first motion, using the phone's GPS and motion sensors on a fixed mount. Recording works offline and without an account.
- Explains every result: source, quality checks, the protocol used and the reasons when no comparable time could be calculated.
- Keeps your cars with declared specifications, photos and immutable setup snapshots, so an old run always shows the setup it was recorded with.
- Compares your own eligible runs, curve over curve, with the setup differences in view.
- Shares, only when you choose to, one run per post with a caption, reactions and comments from owners of similar cars.

Record
Readiness checks while parked, arming only when stationary, hands-free capture, then a private review with the speed chart and quality reasons.

Feed
A chronological feed of public cars you follow. One run per post, make and model filters, comments and reactions. No fastest-first ranking.
Know the limits before you record
Draggo is honest about what a phone can and cannot do. Read this before your first session.
- Phone only. No external receiver, no OBD dongle, no Bluetooth box. Accuracy depends on your phone's GPS and sensors, the mount and the sky view.
- Closed course only. Record at permitted closed-course or private sessions. Draggo has no public-road challenges, no top-speed rankings and no location-based rivals.
- Phone-recorded estimate, not official timing. Every time is labelled PHONE-ESTIMATE. Nothing in Draggo certifies a result.
- One metric. Estimated 0–100 km/h from detected first motion with zero rollout. A 0–60 mph time is a different metric, not a relabelled 0–100 km/h.
- Supported phones only. Unvalidated devices can record, but their results stay private and experimental with no comparable time.
How results are labelled
Every result carries a source label and a quality label. Colour is never the only signal: the text and the code are always shown.
0–100 km/h · first motion · zero rollout
6.8 s
- Checks passed
CHECKS_PASSED - The recording met the protocol's checks: valid launch, valid speed samples, no long gaps, stable mount. This is not an accuracy guarantee and not anti-cheat verification.
- Limited
LIMITED - A time was calculated, but something was weaker than the protocol wants: for example a short gap or reduced fix quality. The run stays private and is excluded from bests and comparison.
- Unusable
UNUSABLE - No comparable time could be calculated. Draggo tells you why: missing launch, target not reached, stale speed, excessive gap, mount movement or interrupted capture. It never invents a time.
Owner-entered horsepower and torque are labelled declared. Draggo does not measure power.
Closed beta
Draggo is being validated on real cars at closed-course sessions before it opens up. The beta is free, invitation-only and for adults. Read the download page to see how invitations work.
