What RevTone does
RevTone generates fictional engine sound on an iPhone. It estimates movement using phone sensors. It does not connect to or control a vehicle. RPM and gear displays are simulated and must not be used as driving instruments.
Safe use
Configure and secure the phone while parked. Do not interact with it while driving. Follow local traffic and noise laws, and use a safe audio level. Sound timing and output depend on the device and audio route; Bluetooth may introduce delay. Exterior-speaker use is unsupported.
Free use and purchase
RevTone provides a cumulative 10-minute live-drive trial on your device. The simulated route and sound previews are for testing and do not consume that time. Unlimited live driving is available through one lifetime App Store purchase for this app. Its price appears in the app before purchase; there is no subscription. Apple handles billing and applicable refunds under its terms. You can restore the purchase from the app’s Upgrade screen.
Availability
RevTone requires a supported iPhone and iOS version. Location access is needed for a live drive. The sound can be affected by GPS availability, phone placement, interruptions, and audio hardware. The simulation remains available without driving.
Intellectual property
RevTone sounds are original real-time synthesis. References to vehicle types or inspirations, if shown in the app, do not indicate affiliation, approval, or endorsement by vehicle manufacturers.
