Useless

They waisted their time making a useless app,DON’T GET THE APP

Inaccurate

Tried the 4-stroke simulation to check it out, the flow of fuel and exhaust is poorly timed and would confuse someone entirely that doesn't already know how it works. Fuel appears to flow into the cylinder while the piston is compressing, and exhaust leaves when the fuel should be flowing in, while a vacuum is being formed. Doesn't instill confidence in the other simulations of things I don't fully grasp yet.
