Two Games.
One App.

Connect to your PlayStation via Wi-Fi and start capturing telemetry in seconds. No mods, no cables, no PC required.

PlayStation 4 & 5 — Time Trial

Gran Turismo 7

Full telemetry via UDP broadcast. AI coach analyses every corner of every lap. Drive in the centre of the track for two full laps - any speed works - and the app auto-detects your layout. When you change circuit in Time Trial, tap Restart Session in the app and drive two laps again to re-detect (GT7 does not broadcast the circuit name in its telemetry).

PlayStation 4 & 5 — Time Trial or Hotlap

Assetto Corsa

Full UDP telemetry via handshake on PS4/PS5. Track name is read directly from the telemetry session. Tap Record Track in the app after loading your session and before starting the lap to capture the layout. Captures sector splits, tire data, and fuel strategy.

Everything a Driver
Needs to Improve.

Six tools, one app, completely offline. Your data never leaves your phone.

Live Telemetry Dashboard

Speed, ABS/TC status, throttle, brake, clutch, RPM, gear, current lap, best lap, and delta - live on both games. Tyre temps, fuel, oil, water, and boost require GT7.

GT7 & AC - core data GT7 - tyre temps, fuel, oil, boost

On-Device AI Coach (Experimental)

A 770 MB language model runs entirely on your phone - no cloud, no internet. After each full lap it produces critical, moderate, and minor coaching notes per corner. Analysis speed varies by device and may take a minute on older hardware.

Lap History

The last 10 laps per game, driver, car and track combination saved with full sector splits, timestamps, and metadata. Filter by game or sort by lap time. Tap any lap to review coaching insights.

GT7 & AC

Track Detection

GT7 auto-detects layout after two full laps driven in the centre of the track - slow speed is fine. When you change circuit in Time Trial, tap Restart Session in the app and drive two laps again to re-detect (GT7 does not send the circuit name in telemetry). For AC, tap Record Track in the app after loading your session and before starting the lap - the track name arrives automatically from the telemetry handshake. If you have not recorded the track before, drive one full lap in the centre so the app can map it.

GT7 & AC - different methods

Fuel Strategy

Fuel level, per-lap consumption, and estimated laps remaining - all live. GT7 exposes this data natively. Not available on AC as the game does not broadcast fuel data over UDP.

GT7 only

Predictive Turn Analysis

Turn-by-turn coaching as you drive - no model download needed. Each corner is analysed in a rolling window and feedback appears immediately after you exit it.

GT7 & AC

What Each Game Provides.

Features depend on what each game broadcasts over UDP. GT7 exposes a richer telemetry package than AC on PlayStation.

Corner-by-Corner
Coaching, Powered
by On-Device AI.

After each complete lap, the app runs a full AI analysis on your telemetry - entirely on your device, with no data ever sent to the cloud. Coaching notes are generated per corner with critical, moderate, and minor severity levels.

AI Coach is an experimental feature. When you enable it, you still get instant turn-by-turn feedback — predictive analysis is always on. Once you complete a turn on a recognized track, AI Coach works in the background and delivers richer per-corner insights as soon as it finishes. Processing time varies by device: more powerful phones complete analysis faster, while older or lower-powered devices may need a minute or more per turn.

T1 - Throttle exit: You peaked at 95% exit phase with throttle. Back off to 75% and release earlier to carry more apex speed. AI

T2 - Brake entry: High throttle but low speed gain on exit. Check your exit line or rear wheelspin limiting acceleration.

T3 - Steering: Corrections are too aggressive for the cornering load. Smoother hands = less scrub = more front-end grip.

Three Steps
to Race Faster.

No hardware, no mods, no subscriptions to anything else. Just your PlayStation, your Wi-Fi, and your phone.

01

Connect

Open Settings, select your game, and enter your PlayStation IP address. Leave it as 255.255.255.255 to use broadcast mode - it auto-connects to either game on the same Wi-Fi. Make sure your router is not blocking the required UDP ports (GT7: 33740 & 33739 - AC: 9996).

02

Race

Start a Time Trial session in GT7, or a Time Trial or Hotlap session in AC. The app immediately starts receiving telemetry. GT7: drive in the centre of the track for two full laps at any speed - the layout auto-detects from position data. If you change circuit, tap Restart Session in the app and drive two laps again to re-detect (GT7 does not broadcast circuit names). AC: tap Record Track in the app after loading your session and before starting the lap - the track name arrives automatically from the telemetry handshake. If you have not recorded the track before, drive one full lap in the centre so the app can map it.

03

Analyse

Review your lap history and compare sector times. Predictive mode delivers instant turn-by-turn feedback as you drive. AI Coach (experimental) generates deeper per-corner insights after each complete lap - fully offline, on your device.

Real Data.
Real Improvements.

AI Insights after a Lap

After each complete lap, AI Coach (experimental) analyses every corner and surfaces coaching notes - critical, moderate, and minor. Speed depends on your device.

Common Questions.

Gran Turismo 7 (Time Trial mode) and Assetto Corsa (Time Trial or Hotlap mode), both on PlayStation 4 and PlayStation 5. Both games broadcast telemetry via UDP over your home Wi-Fi network. Support for additional titles may be added in future updates.
No. After the initial app download and AI model download (~770 MB, one-time), everything runs entirely on your local network and on-device. Your telemetry data never leaves your home.
This is an experimental feature. After each complete lap, the app segments your telemetry by corner and passes it to an on-device language model (~770 MB, downloaded once). The model generates coaching notes - critical, moderate, or minor - covering throttle, braking, steering, and fuel for each corner. Analysis speed depends on your device; older phones may take a minute or more. No data is ever sent to an external server.
The AI model (~770 MB) is downloaded once when you first enable AI Coach mode in Settings. You can use the Predictive analysis mode without downloading it. The download only happens over Wi-Fi and can be triggered or re-triggered from the Settings screen.
GT7 broadcasts telemetry automatically - no in-game settings change is needed. Use Time Trial mode. Leave the IP in the app as 255.255.255.255 for broadcast (works for both GT7 and AC). Both devices must be on the same Wi-Fi. Make sure your router allows UDP on ports 33740 and 33739 (GT7) or 9996 (AC). For track detection, drive in the centre of the track for two full laps - any speed. When you switch circuit in Time Trial, tap Restart Session in the app and drive two more laps to re-detect (GT7 telemetry does not include the circuit name).
After 2 months, the app will ask you to start a subscription to continue. Your saved lap history and recorded tracks are never deleted. If you re-subscribe later, everything is exactly where you left it. You can cancel anytime from your App Store or Google Play subscription settings.
Yes. Tap "Restore Purchases" in the Settings screen. The app connects to your App Store or Google Play account and restores any active subscription tied to that account. No account or login within the app is required.
