AutoTempest is a free iPhone app developed by Tempest Systems Inc. It falls under the Lifestyle category with a subcategory of Shopping. This app aggregates millions of car listings from various top car listing sites in the USA and Canada, such as Cars.com, Truecar, eBay Motors, Carvana, Hemmings, Cars & Bids, Carsoup, and more. It also generates comparison links for other large sites like Autotrader and Cargurus, as well as classifieds like Facebook Marketplace and Craigslist, nationwide.

With AutoTempest, you can find your ideal car easily, as it eliminates the need to search through multiple sites or apps separately. By providing all the listings in one place, you won't miss out on the car you're looking for. The app aims to make car searching smarter and more efficient, allowing you to find your next car wherever it's listed.

If you prefer using AutoTempest in your browser, the website offers all the features and device support. However, if you search for cars regularly and want a faster way to access it, the app might be the right choice for you.

The app is constantly being improved, with a focus on enhancing the advanced search to make it more intuitive. Future updates will include features like optional login to share favorite searches and listings between the app and web, managing saved searches, and eventually, saving and ignoring vehicles, all from within the app. The developers also welcome user feedback and suggestions for further improvements.
