Hello @djchris and welcome to the Community. You need to search the Gallery by store name to see if an app exists. The link I gave you is the web link, but the web link doesn't filter by device. If you search the Gallery on your mobile app (profile picture > Sense > Gallery > slide the toggle to Apps), the results will be specific for the Sense.
