フリックMax!! - フリック入力(+トグル)で日本語入力

This is an app for inputting Japanese characters. You can input Japanese using flick input and English using a QWERTY keyboard or 12-key keyboard (configurable). While there are other free apps that support flick input, such as Gboard, this app has several advantages: it operates smoothly, has easy-to-see keys, the center column is easy to touch, it's easy to type on even on a tablet, the QWERTY keyboard allows input of lowercase and uppercase English letters and all half-width symbols without mode conversion, and the 12-key keyboard allows input of English sentences.
