Finnish Android keyboard that learns your words on the device
...Five to eight suggestions appear in a scrollable row and a long press on a key opens a character menu. The keyboard also offers an on-device translation view, voice typing with the device's speech recognition, a clipboard with pinnable clips, emojis, a cursor mode, a customisable toolbar and password autofill from the suggestion row. Learned words move to another device with a backup.
