This app — is like a browser window specially for Google Spreadsheets. This meens it doesn’t do anything, that wouldn’t do Google Spreadsheets in browser. On the other hand it works exactly as I expect with all latest features of Google Spreadsheets. My usecase: I use this app to work with my sheets and close browser, so that nothing distracts me. P.S. I think it should cost 0,99$, because it’s just a browser app.
