If the apps or website is acting slow, you can check the current status of Duolingo's, Duolingo for School's, and Tinycards' servers and uptime at status.duolingo.com
This page will always show the latest information about servers, technical problems, uptime, outages, and so on. If we are experiencing issues, it is possible that the app or website behave in unusual ways (some features may be turned off or not working as expected). Please be patient as we will be working very hard and as quickly as possible to get everything working smoothly again. Keep an eye on that page for the latest updates.
