Summary: No. An internet connection is required to use RoofSnap's mobile apps and Web app.
RoofSnap stores your project data in cloud storage so that you and other users on your account can access it from anywhere and across multiple devices.
Because this data is not saved to your device, you must have an internet connection to access your projects.
Note: Poor internet connections can result in unexpected behavior when using RoofSnap. If you are working in a location with little to no internet access, save any documents to your device prior to visiting the location to ensure those documents will be available. Save any inspection notes and photos to your device and add them to your project when your internet connection is re-established.
