Press the pedal and the engine roars for real. Just move your finger and 28 different engines come alive — from a 660cc turbo kei car to a W16 hypercar, all the way to a racing V10 that screams to 19,000 rpm. It's a new kind of toy you can just pick up and play. No complicated setup. Drag across the screen and feel how good a good engine sounds. SIMPLE TO PLAY, DEEP IF YOU WANT IT - 28 engine sounds: V-twin, turbo kei car (660cc), inline-4, inline-5, inline-6, boxer-4, flat-6, V6, cross-plane and flat-plane V8s, V10, V12, W16, and a racing V10 to 19,000 rpm - A throttle that reacts to exactly how hard you press: ease in for a soft idle, floor it for a full-throttle scream - Every sound is made live, not a recording on loop — so the same rev never sounds exactly the same twice - Straight-pipe mode in the chassis tuning screen: open up the exhaust for more pops and bangs on lift-off - Haptics that pulse with the revs, so you feel the engine in your hand - Color RPM gauge with a rev-limiter cutout FOR CAR PEOPLE, THERE'S MORE - An H-pattern shifter (switch to paddles anytime) so you change gears yourself - Practice rev-matching: brake, blip the throttle, shift. Nail it and it's smooth; botch it and you feel the driveline thump - Per-cylinder firing and uneven exhaust timing keep it from ever sounding like a loop - Tune each engine: spend miles earned by driving on mufflers, intakes, headers, superchargers, cams and ECU maps, and see your 0–100 km/h (0–62 mph) time, top speed and torque change on the spot - Chassis tuning shared across every engine: weight reduction, aero and a lighter flywheel - A Parts Crate for extra parts, with the odds shown in the app - Garage miles keep accruing even while the app is closed - A Pit Stop summary after every drive: distance, miles earned, and any personal bests - Daily tasks, a login bonus, and achievements you can trade in for perks - Game Center leaderboards for top speed and 0–100 km/h - Invite friends with a referral code for bonus miles WHO IT'S FOR - Anyone who loves engine and car sounds - Anyone who wants a bit of fun tinkering with a car while waiting or on the go - Fans curious what a V12 or flat-6 sounds like without owning one - Drivers who want to practice rev-matching before getting behind the wheel AVAILABILITY You start with the inline-4 and every core feature, with no ads on the driving screen. Driving earns miles that unlock the remaining engines and parts through the unlock tree. The next unowned V6, V8 or V12 engine can be rented for 10 minutes after a short video ad, and straight-pipe mode can be unlocked for 24 hours the same way. An optional one-time purchase removes the full-screen ads shown between engine switches; rentals, straight-pipe trials and mile rewards stay available either way. No subscriptions. Tip: headphones or earphones bring out the fine detail in every sound.

Exhaust Note is not an app that plays back engine recordings. For piston engines, it synthesizes the sound from scratch, every moment, from the firing order created by cylinder layout and crankpin phasing. Why a crossplane V8 rumbles, why a flatplane screams, why a V12 idle throbs — it all comes from the physics of firing intervals. This app computes that physics in real time. ■ Real-time synthesized exhaust - Zero recorded samples. Crank-angle integration → per-cylinder firing → exhaust-pipe propagation, computed every sample - Distinct primary pipe, mid-pipe and muffler model for every engine - Muffler continuously adjustable from straight pipe to quiet ■ Engine collection - 22 engine and motor presets: inline-3 through V12, two-, three- and four-rotor engines, a 300 kW electric motor and six motorcycle engines - 12 transmission presets: manual, sequential, dual-clutch, automatic, EV single-speed reduction and motorcycle 6-speed sequential, paired with compatible powertrains - Pick a motorcycle engine and the view becomes a motorcycle that leans into corners, with quickshifter, intake and dry-clutch sounds - Crossplane vs flatplane V8 — same eight cylinders, completely different sound - Firing order and rumble index shown as specs ■ Pop and bang + flames - Afterburn pops on throttle lift and downshifts - Flames at the 3D exhaust tips, same instant and same bank as the sound ■ Tunnel mode - Reverb that wraps the sound in wall reflections, like driving into a tunnel ■ A living 3D machine - Crankshaft, pistons and connecting rods rotate in phase with the sound - Gearbox cutaway: constantly meshed gear pairs and real synchro-sleeve movement - Observe the mechanism at 1/10 slow motion, or switch to real time for phase match ■ The feel of driving - Torque-converter launch, rev matching, manual H-pattern shifter - Haptics on rev limiter, wheelspin, shifts and ABS - Analog pedals: press position controls pedal travel ■ Electric drive - Motor, inverter, underfloor battery and fixed reduction in 3D - Original sound synthesized from motor speed, load and regeneration, without recorded samples - Simplified battery charge, energy use and regenerative braking ■ Garage, dyno and mechanism explorer - Name and save engine, transmission, boost, exhaust, body, color and assist combinations; restore the last configuration - Compare torque/power curves and estimated acceleration with shared vehicle mass and road conditions; optional matching gear ratios for combustion setups - Move through the operating cycle and choose a gear to inspect the mechanism ■ Circuit driving - Drive GT and four-door coupe models on the test circuit or an approximate 20.7 km Nürburgring Nordschleife based on public data, with forests and elevation changes - Adjustable graphics quality and saved accelerator/brake modes, pedal response, steering and assists - Local best laps are separated by circuit, engine and boost class; the three-rotor, four-rotor, electric and motorcycle powertrains currently keep records on the device only Power, acceleration and EV battery figures are estimates from simplified simulation, not production-vehicle measurements.

Verdict

The call

The clearest difference is ratings volume: Engine Sim at 1.3K against Exhaust Note's 14. Engine Sim also leads on chart position (#71 vs unranked). Exhaust Note's advantage is review sentiment (94% vs 83%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Engine Sim sells 10 one-off in-app purchases and Exhaust Note sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.6 for Engine Sim against 4.7 for Exhaust Note. That said, the two scores are not equally well evidenced: Engine Sim has 1.3K ratings behind it against 14, so its average is the more settled of the two. Written reviews are what separate them: 83% of Engine Sim's written reviews are positive against 94% of Exhaust Note's.

UpkeepUpdate frequency

Engine Sim ships an update every 3 days, Exhaust Note every 4 days. Both last shipped on November 13, 2026.
