Assetto Corsa is almost a decade old, but its modding community and third-party tooling have kept it more relevant than most newer sims. The right apps turn it from a driving game into something that behaves like a real race weekend — with proper setup work, strategy, live data and telemetry analysis. This is the list of apps that actually matter in 2026, grouped by what they do.
Setup & tuning apps
Track Engineer v6 PRO — AI setup advisor
The only app that builds a setup from your telemetry instead of handing you a generic one. You run laps in AC, export the telemetry as .CSV or .LD, drop it into Track Engineer, and the AI reads how you actually drive — brake pressure, throttle application, slip angles, where you lose time — and returns concrete values for suspension, aero, alignment, brakes, tyres and gearing.
You bring your own AI key (OpenAI, DeepSeek or Claude), so you control the model and the cost — typically a few cents per setup. You can add written or voice feedback ("understeer in slow corners", "car snaps on exit") and regenerate until it fits. Works with stock and modded cars.
Price: €19.90 one-time, no subscription. Best for: league and endurance racers who need a competitive setup per track without spending hours testing blind. See Track Engineer →
RaceDepartment / OverTake.gg setups
Not an app, but the most common source of setups for AC. The community uploads setups per car/track that you drop into the game folder. The catch: those setups are built by one specific driver for their driving style. If your reference points differ — and they usually do — the setup feels wrong or slower than the default. Useful as a starting point, rarely optimal as-is.
Price: free. Best for: quick baseline when you have no time and no telemetry.
Race strategy apps
SimRacing Planner PRO — strategy calculator
A fully automatic race-strategy planner built for Assetto Corsa. You feed it stint length, fuel consumption, pit-lane loss and tyre data, and it computes the optimal pit-stop strategy, per-stint lap times accounting for the fuel mass effect (the car gets faster as it gets lighter), rain scenarios and lets you compare strategies side-by-side with interactive charts.
The fuel mass effect alone is what most manual strategies get wrong — every 10 kg of fuel costs roughly 0.3–0.5 seconds per lap depending on the car, and ignoring it skews the entire stint plan. Price: €12.00 one-time. Best for: endurance and league races with mandatory pit stops. See Planner PRO →
Manual fuel calculators (pitskill.io, simracing.gp)
Free web tools that compute fuel load from lap time and stint length. Good enough for sprints; they don't account for fuel mass effect, pit-lane loss or tyre deg, so they fall short for endurance. Price: free. Best for: quick sprint fuel math.
Tyre pressure apps
Tyre Coach — live pressure advisor
The only tyre app that goes beyond showing the number. Tyre Coach runs as an overlay outside AC, reads your real hot pressure while you drive, compares it against the ideal window of the actual car you're in (Kunos or mod), and tells you exactly how many setup-menu clicks to adjust — "raise front-left 2 clicks" — instead of leaving you to guess.
The key difference: it reads the ideal pressure from the car's own data, not from a generic table. That's why it can give a concrete instruction instead of an approximate tip. Price: free. Best for: anyone who has ever chased tyre pressures by trial and error. See Tyre Coach →
ProTyres & Sidekick
In-game apps that display live tyre pressures and temperatures. Solid for monitoring, but neither tells you what to do with the number — that's the gap Tyre Coach fills. Price: free. Best for: live pressure monitoring.
Telemetry & data apps
MoTeC i2 Pro
The professional standard for telemetry analysis in real and sim racing. AC exports .LD files that MoTeC reads natively. You get full channel access — wheel speeds, dampers, slip angles, G-forces, brake temps, ride heights — and the ability to build any overlay or comparison you want.
The downside: steep learning curve. Most drivers open it once, see 40 graphs and close it. That's exactly the problem Track Engineer solves — it reads the same telemetry and tells you what to change, no MoTeC expertise required. Price: free (standard), paid Pro add-ons. Best for: data-literate racers who want full control.
Track Engineer (telemetry reader)
Worth mentioning separately: Track Engineer is also a telemetry reader. It parses 150+ channels from .CSV and .LD files locally, and the AI step only sends the summary needed to reason — never raw channels in bulk. So you get the benefit of telemetry analysis without needing to learn MoTeC. See Track Engineer →
Content & launcher apps
Content Manager
The de facto launcher for Assetto Corsa. Replaces the default UI, manages cars/tracks/mods, handles CSP and Sol settings, weather, VR configuration and saves enormous amounts of time. Almost every regular AC player uses it. If you only install one app on this list, it should be this one — without it, AC feels like 2014.
Price: free (donation-supported). Best for: everyone.
Custom Shaders Patch (CSP)
The graphics overhaul that keeps AC visually competitive with sims released years later. Adds dynamic lighting, better reflections, weather effects, VR improvements and a long list of visual fixes. Usually installed through Content Manager. Price: free. Best for: everyone with a GPU that can handle it.
Dashboards & overlays
SimHub
The standard dashboard and telemetry overlay for sim racing. Supports AC, ACC, iRacing, RF2 and others. You can build custom dashboards on phones, tablets, secondary monitors or dedicated displays, with shift lights, fuel deltas, tyre temps and anything else the game exposes.
Price: free tier, paid for advanced features. Best for: anyone wanting live data on a second screen or mobile.
Crew Chief
A voice race engineer that calls out gaps, fuel, tyres, flags and position over your headphones. Not a setup tool — it's the radio side of the engineer role. Works with AC and most other sims. Price: free / donation. Best for: racers who want audio calls without a human spotter.
How to choose what you need
You don't need every app on this list. The combination depends on what kind of racing you do.
Casual / hotlapping: Content Manager + CSP. That's it. The game looks and runs better, and you don't need data tools.
Online sprints: add Track Engineer (so the setup actually fits you) and SimHub (so you see fuel and temps live).
League racing: Track Engineer + SimRacing Planner PRO + Tyre Coach. Setup, strategy and pressures are the three things that decide league results beyond raw pace.
Endurance: the league setup plus Crew Chief for voice calls and MoTeC if you want to dig into stint data afterwards.
The one thing worth repeating: a generic setup from a forum will never be as fast as one built from your own telemetry. That's the whole reason Track Engineer exists — and why it's the only app on this list that builds a setup instead of handing you someone else's.
The setup and strategy half of your garage
Track Engineer builds the setup from your telemetry. SimRacing Planner PRO calculates the strategy. Tyre Coach handles pressures live. All one-time payments, no subscriptions.
Frequently asked questions
What are the best apps for Assetto Corsa in 2026?
Track Engineer (AI setup), SimRacing Planner PRO (strategy), Tyre Coach (pressures), Content Manager (launcher), CSP (graphics), SimHub (dashboards) and MoTeC (telemetry). The right combination depends on whether you race offline, in leagues or endurance.
Is there an AI setup app for Assetto Corsa?
Yes — Track Engineer. Upload telemetry, connect your AI key, get a personalized setup with concrete values. €19.90 one-time.
Are these apps free?
