English Finnish best dictionary translator - Englanti Suomi paras sanakirja kääntäjä

I don't know where they get the data but this is by far the most complete Finnish-English dictionary I've found out there. But the UI could use some improvement. For example, a back button, the ability to tap words to go quickly to definitions, rather than having to long-press and select from a menu, and the ability to switch language direction on a single tap. It appears that the developer doesn't use the app themself and so doesn't get annoyed by these easily-improved niggles. UPDATE: After more than a year, NO updates to improve the UI. It's a shame, since the dictionary data is so good. UPDATE 2: App now constantly uses the network (wheel always spinning in upper left). What is it doing?
