The Viper smart watch functionality will be available for free on both Android and iOS via the company’s newest version of the Viper SmartStart 4.0 app. Version 4.0 of the Viper app is compatible with all Viper SmartStart hardware, which means that all existing and future Viper users who purchase an Apple Watch or Android Wear product will be able to tap into the features at no additional cost. Additionally, the new version of the app has been updated with a more intuitive home screen that offers faster access to the primary controls. To take full advantage of the functionality inherent in the Viper SmartStart app though, users will need to purchase a Viper system from any authorized dealer; prices start around $149.99.
