ATOK for Android[Professional]

ATOK for Android[Professional] is a premium Japanese input system that brings desktop-class conversion accuracy and intelligence to your smartphone. Part of the ATOK Passport subscription service, this app lets you maintain the same typing environment across up to 10 devices—phones and computers combined.

The conversion engine analyzes the context of what you're typing and adapts to your writing style. Whether you're composing quick social media messages or formal emails, the evolved predictive conversion feature learns from your patterns and suggests naturally flowing Japanese. The system also corrects touch errors that are unique to smartphone typing, so even hurried input becomes accurate without manual intervention.

Choose your preferred input method from four options: the original Flower Touch gesture input, flick input, mobile phone (T9-style) input, or a standard QWERTY keyboard. Switch between numeric and letter layouts with a single tap. Keyboard themes come in 17 colors, and you can load custom images as backgrounds. Adjust the keyboard size by sliding—shrink it to one side for comfortable one-handed use on larger screens, or expand it for precision typing. Long sequences of letters, numbers, passwords, and email addresses input just as smoothly as they would on a computer.

The conversion engine handles complex tasks automatically: it learns proper names and place names, converts lengthy readings in a single tap, and improves its accuracy each time you make a choice. If a suggested character or word didn't match what you intended, the system remembers your correction and applies it next time. Emojis, emoticons, and symbols are organized by category and display large for easy selection without hesitation.

ATOK Passport [Premium] unlocks access to the full ATOK Cloud Service, including premium dictionaries like Kojien and advanced text proofreading tools. All Premium features are available without usage limits. Your custom word lists, saved phrases, and input settings sync seamlessly across all registered devices, so your personalized typing experience travels with you.

ATOK for Android[Professional] requires an active ATOK Passport [Premium] subscription. New users can sign up directly within the app using a Just Account. The app supports Android 8.0 through 16 and works best on standard device configurations without custom ROMs or root modifications.
