Features
1) Seamlessly transforms into different type of engines
Select from inline to V-type, or other multi-cylinder engines,
and watch the running engines transform over continuous CG animation.
Enjoy watching the inline engine camshaft separate into two parts as it transforms into the V-type engine and
how phase angle modulation between cylinders makes the crankshaft rotate, separate, and combine into many engine formations.
2) Add Engine Sound (In-App Purchase)
Developed in technical collaboration with "CAI MEDIA CO.,LTD.", the developer of the iPhone app featuring innovative synthetic engine sound, "RealEngineSim" this new feature will add a variety of realistic engine sounds ranging from different number of cylinders to explosions with unequal intervals and cylinder rest.
Engine Sound Add-On is available via In-App Purchase.
3) Accelerator Control
Accelerator control is available during engine sound replay. Tilt iPhone to different degrees as if pressing the accelerator pedal. Tilt forward horizontally (as if pressing the accelerator) to activate the accelerator, and erect vertically (as if releasing the accelerator) to deactivate it.
Furthermore, you can race the engine by tapping the center of rev counter.
4) Addition/expansion of engines
There are currently 22 types of engines registered. Through automatic network updates, continuous expansion is planned.
In addition, there are functions installed that allow users to newly register and edit engines.
Able to adjust setting for engine bore stroke, firing order, and ignition timing.
Easily replicate on the iPad, engines with unequal combustion intervals for two-wheelers, Inline-four crossplane or V5.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
