EVERY LAP. DownloadClient
EVERY CORNER.
Every Tenth.

Drive. The telemetry client logs every lap to the leaderboard while the AI coach talks to you over the radio — calling brake points and catching your mistakes as they happen. Back in the pits, track analysis shows where the time went, and the AI race engineer rebuilds your setup.

VOICE COACHING,
CORNER BY CORNER

A coach that speaks to you over the radio and learns on your own laps — your braking points, your best sectors, the corners where you bleed time. It points out your mistakes in real time, while you’re driving: brake later here, throttle earlier there. After the session it debriefs you on where the next tenths are hiding.

The moment you’re clear of a corner, an on-screen overlay draws your line and speed against your best pass of it, with brake and throttle pedal traces stacked underneath — so you can see exactly where the corner went before you’re back on the power for the next one.

The whole radio speaks English, Spanish, Brazilian Portuguese, German, Italian, Hungarian, Japanese or Hindi — every call, not just lap times: flags, the spotter, weather, fuel, sector deltas and the corner-by-corner coaching. The app’s own interface follows the same eight languages.

TRACK
ANALYSIS

Every lap you log gets the full engineer treatment. Overlay your lap against the leaderboard reference — or an AI-estimated ideal — and compare racing lines, time delta, speed, throttle, brake, steering and gear, metre by metre. Hotspots rank the corners where the time goes, and the AI coach turns them into concrete instructions to cut your lap time.

F1, IndyCar, GT World Challenge, BTCC, NASCAR, WEC, club racing and more: register for a round, then drive its circuit in a car that fits, from a week before the race weekend to a week after it. Your best valid lap is your result, ranked against every driver entered. In F1, F2 and F3, the event page also lists each real driver's best lap of that weekend, so you can see how your time stacks up against the real grid.

GET THE
CLIENT

A live crew on your radio while you drive. The AI coach talks you through your driving in real time — braking points, corner-by-corner advice, where you're losing time to your best lap — while a pit-wall announcer calls lap times, tyre state, session time and laps remaining. All spoken aloud, corner by corner.

The same small Windows app logs every valid lap — with sector times — to the hotlap leaderboard as you set them. Supports iRacing, Automobilista 2, Assetto Corsa Competizione, Assetto Corsa EVO and Assetto Corsa, and speaks English, Spanish, Brazilian Portuguese, German, Italian, Hungarian, Japanese and Hindi. Run it, confirm the link in your browser, race.

Talk back to it: hold a push-to-talk button and ask — fuel, the gap, your last lap, where you’re losing time — or switch the coach, the spotter or an overlay widget on and off. Plain speech, recognised on your PC.

Download for Windows .exe .zip if .exe blocked

First start takes a while. The first start after downloading or updating can take several minutes while the app unpacks itself. A “Starting…” window shows meanwhile — please wait and don't start it again. Later starts are quicker.

Windows will warn you the first time you run it: Windows protected your PC. Click More info, then Run anyway.

Why does it say that?

The client isn't code-signed yet, so SmartScreen doesn't recognise the publisher and warns about anything it hasn't seen before. It's reacting to the file being new, not to anything it found inside it.

If your browser blocks the download outright, take the .zip instead and extract it.

Quick start

  1. Download and run TheTenths Client (Windows). The first start can take several minutes: wait for the window rather than starting it again.
  2. First run shows a short code and opens your browser — sign in (or register) and press Link this PC.
  3. Press Start, then get in the car. The crew comes on the radio and your valid laps post to the leaderboard.
  4. The Coaching light in the client reads learning until the coach has a reference lap to measure you against, then advising once it is calling corners.

Settings save automatically — the app remembers them next time, and this PC stays linked.
