Live telemetry, AI corner coaching, and lap-by-lap analysis for Gran Turismo 7 and Assetto Corsa - streaming directly to your phone over your home network.
Supported Platforms
Connect to your PlayStation via Wi-Fi and start capturing telemetry in seconds. No mods, no cables, no PC required.
Full telemetry via UDP broadcast. AI coach analyses every corner of every lap. Track layouts auto-detected after one full lap.
Full UDP telemetry via handshake on PS4/PS5. Track name is read directly from the telemetry session. Captures sector splits, tire data, and fuel strategy.
What You Get
Six tools, one app, completely offline. Your data never leaves your phone.
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.
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.
Every lap saved with full sector splits, timestamps, and car/track metadata. Filter by game or sort by lap time. Tap any lap to review coaching insights.
GT7 auto-detects layout and track name after one full lap using position data. For AC, the track name is read automatically from the telemetry handshake - no entry needed.
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.
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.
Telemetry Availability
Features depend on what each game broadcasts over UDP. GT7 exposes a richer telemetry package than AC on PlayStation.
Not all data fields are implemented yet. As the community grows and driver feedback comes in, support for additional telemetry channels and new game integrations will be added in future updates.
AI Coach - Experimental
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.
This feature is experimental. Analysis quality and speed vary by device. Older or lower-powered phones may take a minute or more per lap to generate insights. Use Predictive mode for instant turn-by-turn feedback while AI Coach is processing.
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.
Live Telemetry
The live dashboard streams your car's full telemetry package at up to 60 Hz. All four tire temperatures, fuel burn, oil and water, boost pressure, sector splits with personal best comparison, and a scrolling delta gauge - visible at a glance.
Setup in Minutes
No hardware, no mods, no subscriptions to anything else. Just your PlayStation, your Wi-Fi, and your phone.
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).
Start a session in-game. The app immediately starts receiving UDP telemetry. Drive as normal - the app records every lap in the background. For GT7, complete one full lap to let the app auto-detect your track layout. For AC, the track name is read automatically from the telemetry session.
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.
See It in Action
After each complete lap, AI Coach (experimental) analyses every corner and surfaces coaching notes - critical, moderate, and minor. Speed depends on your device.
Real-time track map view with telemetry overlay and live sector delta - showing current vs personal best lap split by split.
