The NIOSH PPE Tracker mobile app can help healthcare and non-healthcare systems track their personal protective equipment (PPE) inventory. Facilities can use the app to calculate their average PPE consumption rate or “burn rate.” The app estimates how many days a PPE supply will last given current inventory levels and PPE burn rate. Based on the PPE Burn Rate Calculator Excel spreadsheet, the app features several improvements, including an easy-to-use interface and the ability to add restock. The app is available for both iOS and Android devices.
