Nope. Although an Internet connection is needed to download the iTOVi app and to log in, scans can be performed without your mobile device being connected to the Internet. However, you will need an Internet connection to share the iTOVi report. iTOVi also requires you to regularly synchronize your system. These synchronizations do require an Internet connection and are done automatically. Please keep in mind that your mobile carrier’s standard fees apply when using cellular data to transmit data through the iTOVi.
