TheTenths coach reads your telemetry while you drive and talks to you over the radio, corner by corner, the way a race engineer would. It runs inside the free telemetry client, learns on your own laps, and gets more specific the longer you drive.
“Copy, you’re early on the brakes. Trust it, brake later.”
Lap 4 · Turn 7
“Pick the throttle up earlier — the straight starts at the apex.”
Lap 6 · Turn 7
“Turn 7, that’s your best through there — two tenths quicker.”
Post-Session Debrief
“Exits are money. Open the throttle sooner and take the interest.”
On the radio, as you drive
Approach“Entry was 3 meters wide last lap, tuck it in this time.”
Brake point“Brake!”
Mid-corner“Get on the power!”
Exit“Turn 7, that's your best through there.”
Before the corner: what went wrong there last lap, in time to fix it.
On the brake point: “Brake!” exactly where the reference brakes, only in the corners you keep missing.
In the corner: instant “More brake!” and “Get on the power!”, plus wheelspin and slide warnings.
After it: a word when you beat your best through it.
A corner you drive well stays quiet. The coach learns on your own laps and speaks when there is something to fix, so the calls get more specific the longer you drive.
The corner overlay
Here you turned in later and ran wide on the exit, and your brake release came early.
Your line against your best, drawn the moment you clear the corner.
Speed, brake and throttle traces stacked underneath, so you see where the corner went.
Your costliest corner stays on screen all lap, with its advice and what it costs, until you drive it clean.
Briefing and debrief
Briefing
At the start of the session: the summary of a written briefing, the weather, and the reference lap you are measured against. The full briefing is on screen.
Debrief
At the end: where the next tenths are hiding, corner by corner.
Habits, not just corners
A danger corner on your lap map: the red band marks it, and the count says how many times it has caught you out.
Habits: the same fault across your slow, medium or fast corners is called once, not corner by corner.
Danger corners: a spin or off-track in 3 of your last 5 laps, marked in red on your lap maps.
Crossed off once you have fixed it, with a well done on the radio.
Remembered between sessions, so the coach picks up where it left off.
Your lap against the reference: the leaderboard's fastest, or an AI-estimated ideal lap.
Lines, delta and traces: racing lines on the track map, time delta, speed, throttle, brake and steering.
Hotspots: where the time goes, and why.
Your incidents in red: spins and off-tracks on the map, and the corner costing you invalid laps. Only you see them.
Everything the coach catches
The full list, grouped by when you hear about it: on the radio the moment it happens, on the approach to a corner you got wrong last lap, as a habit across a type of corner, and in the analysis after the session.
Live, the moment it happens
Missing a brake point
“Brake!” right on the reference brake point, in corners where you have been braking early or late over your recent laps. Arriving well over the reference speed gets a hotter “Brake, you're hot!”, every time.
Not enough brake in the corner
“More brake!” the moment your brake pressure falls behind the reference's at the same point of the corner.
Too little throttle in the corner
“Get on the power!” when your throttle falls behind the reference's in the corner you are driving.
Late to the power
“Push!” at the reference's acceleration point, in corners where you got on the throttle late last lap.
A gear too high
“Gear down!” on the approach to a corner you took in a higher gear than the reference last lap.
Wheelspin and traction control
“Too much throttle, ease off!” when the rear tyres spin up under power or the game's traction control is cutting hard.
Rear sliding
A warning when the rear slides mid-corner. Repeats are spaced further apart as a session goes on, so a car that moves around does not turn it into noise.
Off track
“You're off! Ease it back on”, and a word when the lap has been invalidated.
On the approach, from your last lap
Racing line
Entry, apex or exit wide or tight, with the miss in metres: “Entry was 3 meters wide last lap, tuck it in this time.”
Braking too early
Lifting and coasting into the corner, or braking well before the reference: “You're early on the brakes. Trust it, brake later.”
Coasting on the exit
Sitting between brake and throttle on the way out instead of committing to the power: “Late to the power. Get on it earlier.”
A corner that keeps catching you out
A spin, off-track, oversteer, rear slip or understeer at the same corner on repeated laps gets a warning before you reach it, with the fix. Once you have driven it clean, you hear that too.
Habits across a type of corner
Slow, medium and fast corners are watched separately. A fault becomes a habit when it shows in at least two corners and at least half of the corners of one type. It is called once, with the fix, saved to your driving patterns, and crossed off after two clean laps through that type of corner.
Spins
You keep losing the car. Fix: patience, rotation first and power second.
Off-track excursions
You keep running off. Fix: less commitment on entry, stay on the tarmac.
Oversteer
The rear keeps stepping out. Fix: settle the car before the power.
Rear slip
The rear keeps slipping through the corner. Fix: smoother steering and throttle together.
Understeer
The front keeps washing wide. Fix: slow the entries a touch and let the front bite.
Wandering brake points
Your brake point moves from lap to lap. Fix: pick fixed markers and hit them.
Under-braking
You are not reaching full brake pressure. Fix: trust the initial hit.
Brake pumping
Letting off the brake and pressing it again on the way in. Fix: one firm press, then ease off it smoothly.
A gear too high
You take the corners a gear above the reference. Fix: one more down the box before the apex.
Throttle pumping
On, off and on again out of the corners. Fix: one smooth application every time.
Danger corners
A corner where you spin or go off in three of your last five laps is saved as a danger corner for that track. It is marked in red on your lap maps with the number of times it has caught you out, the coach warns you on the way in, and three clean laps through it clear it.
After the session: where the time goes
Track analysis compares each lap with the reference and names what is costing time at each hotspot:
Braking too early
Rear sliding — scrubbing speed
Releasing the brakes too early — no trail braking
Carrying less apex speed
Less throttle on exit
More steering — scrubbing speed
Line & technique
And when many of your laps at a track are invalid, the lap page names the corner throwing them out, whether you are losing the car there or running wide, and how many invalid laps show no recorded incident at all, which points to kerbs, pit entry or contact.
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.
