RevCounter is a free, user-friendly Assetto Corsa dashboard app available on Android. It provides a convenient and accessible way to monitor important race information without the need for additional software on your computer. Simply start your Assetto Corsa race and open RevCounter.

The application offers a basic dashboard display, showing essential information such as speed, current gear, RPM, ABS, TC, lap time, and best lap time. With these key metrics readily available, you can stay focused on your race and make informed decisions to improve your performance.

RevCounter is designed to be user-friendly, making it easy for both novice and experienced racers to navigate and understand. Its intuitive interface ensures that you can quickly access the information you need, allowing you to stay engaged in the race without distractions.

Whether you're a casual racer or a dedicated enthusiast, RevCounter is a valuable tool to enhance your Assetto Corsa experience. It's worth noting that the application should also work with PS4, providing compatibility across different platforms. While I haven't personally tested it on PS4, there is no apparent reason for it not to work.
