As a concept, this app is fantastic. You can keep track of all your shows across streaming platforms, and tell the app which platforms you have. However, the latest version has functionality regression. It wont let you tick the watched checkbox without clicking through to the episode now, and the episode data often takes a long time to load, or times out. Im also finding duplicate episodes in at least one show, which may be a factor of their data provider.
