App tracks tank levels for grills
Blue Rhino’s Rhino Gauge app alerts users when the propane in their grill tanks is getting low. According to the company, users must answer a few questions about how they grill and the last time they bought propane to receive information on their tank fill levels. A timer built into the app can track grilling time and help users predict when they will need propane. The app also displays Blue Rhino locations so users can pick up new propane tanks. The free app is available for download for iPhone and Android devices.
