About

Kai Reads

Read full description

Kai Reads turns learning to read into a real adventure. Join Kai, a curious kid explorer, on a trip across four planets โ€” each one built around a different reading skill kids need to become confident readers. WHAT KAI READS TEACHES Dino Planet โ€” Sound It Out Practice phonics by sounding out letters one at a time, then blast the word to watch it come together. Haunted Moon โ€” Build Words Drag letter tiles into the right order to build spelling and word-construction skills. Web Station โ€” Catch Sight Words Quick-recognition rounds for the high-frequency "sight words" every early reader needs to know by heart. Story Planet โ€” Read a Story Short, illustrated stories read aloud line by line, building reading fluency and a love of stories. NOW SUPPORTS IPHONE DUO Kai Reads now supports iPhone Duo. Closed, open, or partly open, in landscape or portrait, every screen adapts to the fold and stays centered and readable, clear of the camera and status area. BUILT FOR REAL KIDS, NOT JUST SCREENS Kai Reads speaks every word aloud using natural, on-device speech โ€” no internet required to play. In Parent Settings, grown-ups can fine-tune the speaking speed and voice pitch, and pick from the best voice installed on the device (including Apple's Enhanced and Premium voices, when downloaded). STARS, STICKERS & GOALS Every correct answer earns a star. Earn 5 stars in a game to unlock its collectible sticker in Kai's Sticker Book. Parents can set daily and weekly star goals from Parent Settings, and Kai cheers when a goal is hit โ€” turning practice into a small, repeatable win instead of an open-ended screen session. GAME CENTER Total stars and unlocked stickers sync to Game Center, so progress is never lost and kids can see their own growth over time. MADE FOR PARENTS WHO ARE PICKY ABOUT SCREEN TIME No ads. No in-app purchases. No accounts, logins, or data collection beyond what's needed for Game Center. Just a focused, kid-safe reading game designed to be handed to a young reader with nothing to worry about. Kai Reads works on iPhone (including iPhone Duo) and iPad, in landscape or portrait, and is best enjoyed with the sound on.
