FAQ

Short answers. For anything not here, send an email.

Is it free?

Yes. The default inline-six and all gearbox, exhaust, and tuning settings are free. Switching to a different non-default engine requires a rewarded ad and confirmation of its reward. You can pick a rewarded engine again without an ad for 24 hours. Reopening the app restores the last engine saved on your device, or the default engine if no saved choice is available. In the Google Play and App Store apps (version 1.0.2 or later), if the ad network responds without an ad (no ad is available or ad serving is limited), the app switches without an ad and gives the same 24-hour period. Other ad errors (such as a connection failure or timeout) and closing the ad before the reward is confirmed do not change your engine. There are no in-app purchases or points.

When do ads appear?

A banner appears at the bottom of the screen. To switch to a different non-default engine, you choose to watch a rewarded ad in the prompt. Your engine stays the same unless the reward is confirmed. However, in the Google Play and App Store apps (version 1.0.2 or later), if the ad network responds without an ad, the app switches without one. Full-screen ads do not unexpectedly interrupt starting, shifting, or changing settings.

Where can I get it?

In the download area on the home page, tap the Google Play badge for the Android app, the App Store badge for the iPhone and iPad app, or the Toss Mini App badge to use it inside Toss with no install.

There is no sound.

Check your device's media volume and silent switch, and make sure sound is turned on in the app settings. Sound pauses while an ad or dialog is open and resumes when it closes.

Are these real car engines?

No. They express general traits like cylinder layout and rev character and are not tied to any vehicle or brand. The revs and load shown are simulation values inside the app.

Which engines and gearboxes are included?

Settings offers 12 inline, V, flat and rotary engines, plus manual, automatic and dual-clutch transmissions.

Do I need an account or permissions?

No. You can use it right away with no sign-in or device permissions required, and settings are stored only on your device.
