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.
Crownfall
Read full descriptionHide full description
Crownfall is a real-time space strategy game played on one shared galaxy that keeps running whether you are watching or not. Claim worlds. Build fleets. Send them across the map to colonise, scout, salvage and take ground from other commanders. Every world you hold produces for you, every fleet takes real time to arrive, and anything you leave undefended is something somebody else can come and take. KNOW FRIEND FROM FOE Every commander's crest wears a frame: teal for you and your clan, green for your allies, and shades of red for rivals by strength. Clan badges show who stands with whom at a glance. CLANS AND ALLIANCES Find a clan or found your own, choose who can join, and coordinate in clan chat. Sign alliances, plan rallies and strike together. Chat is built in, with report and block on every message. SEASONS AND RANKINGS Climb the season leaderboard for commanders, clans and alliances. When a season ends you keep your Crown Medals, your Legacy and the ranks you earned; the map starts again. LIVE EVENTS Limited-time surges (double metal, faster fleets, extra experience) change how every commander plays while they run. YOUR COMMANDER Level up, spend skill points, pick your face and crest, and watch your empire grow across the star map. A guided tour shows you the ropes in four quick stops. Crownfall is in open alpha and plays in landscape: turn your phone sideways. Crownfall is free to play. Optional in-app purchases may be offered. Tell us what breaks: support@kyvarr.com

Verdict
The clearest difference is ads: Crownfall at none against Engine Sim's shown. Crownfall also leads on iOS requirement (16.4 vs 18.0). Engine Sim's advantage is chart position (#77 vs unranked). On price, update cadence, in-app purchases and device support there is nothing between them.
