ZUS - Save Car Expenses is a free Android app designed by No NDA Inc, a company that specializes in travel and navigation. The app works with ZUS Smart Car Charger, nonda Smart Car Charger, ZUS Smart Tire Safety Monitor, ZUS Vehicle Health Monitor, and ZUS Wireless Backup Camera. The app helps you locate your car, track your mileage log, and monitor your tire pressure and engine health in real-time. It also offers a wireless backup camera that provides a 170-degree field of view right on your smartphone. ZUS is now compatible with certain third-party OBD-II devices that can be used to scan your vehicle. The app is user-friendly and easy to install, with a simple interface that allows you to choose between compass and map view to locate where you parked your car. However, ZUS may not locate your car indoors or in underground parking lots where it cannot receive a GPS signal. The app also offers premium service subscriptions, including a free mileage log feature for your first 60 drives every month.
