Using a GPS tracking app can reduce costs, particularly if you already have compatible smartphones or tablets. These apps often have lower or no hardware costs, and some offer free or low-cost subscription plans. However, app-based tracking has limitations compared to dedicated GPS devices. Smartphone battery life, data usage, and potential coverage gaps can impact tracking reliability. Additionally, apps may not offer advanced features like engine diagnostics, geofencing, or secure, tamper-resistant installation. If basic location tracking meets your needs, a GPS tracking app could be a cost-effective solution, but for comprehensive tracking, investing in dedicated hardware may be more suitable.
