Yes. Fotor has multiple platforms including Fotor website, Fotor mobile app (iOS/Android), and Fotor Mac/Windows for desktop.
Though there are some difference among these platforms, like design resources, beauty feature and some others, most of the features are same.
You can sign in with the same one account to different platforms of Fotor. In particular, when you subscribe to Fotor Pro or Pro+, your membership is available on all Fotor platforms.
