Boop is a kaomoji keyboard for iPhone: 24,563 cute Japanese text faces and emoticons, sorted by mood, searchable in a tap, and ready in every app you type in. EVERY FACE, ONE TAP AWAY Boop lives in your keyboard, so the faces come with you. Chats, DMs, notes, email, comments, anywhere there is a text field. Tap a face and it lands in your text. No copy and paste. SORTED BY MOOD 37 moods. Happy, love, sad, cats, dogs, bears, sleepy, dramatic, table flipping, shrugs, sparkles and more. Browse the mood you are in instead of scrolling one endless list. SEARCH THAT FINDS FACES Type happy, bear, angry, shrug or cat and get the faces that match, instantly, on a keyboard that feels like the real one. The whole library is indexed and searched on your phone. SAVE THE ONES YOU USE Press and hold a face to save it. Saved faces ride at the front of the keyboard, and they show up in the app too. BUILT TO FEEL FAST The library ships inside the app as a local database, so opening the keyboard, switching moods and searching never wait on anything. FREE, AND ACTUALLY FREE No ads. No accounts. No subscriptions. No analytics. No network code at all. ABOUT FULL ACCESS iOS asks for Full Access before any third-party keyboard can do more than type. Boop uses it for two things: keeping your saved faces in sync with the app, and haptic feedback when you tap a key. Boop has no network code, so nothing you type can leave your phone, ever. The keyboard works without Full Access too, you just lose sync and haptics. Kaomoji, emoticons, Japanese emoji, text faces, lenny faces, ASCII faces, whatever you call them. They are all in here.
