Sometimes on a long car ride, sometimes before nap time, sometimes whenever they say "tell me a story"... Lumi is your child's storytelling companion for every moment of the day. Lumi is an audio story, learning game, and bedtime app crafted for children ages 3–6. Every story comes to life with professional narration, and as your child listens, each spoken word lights up on screen. Story time quietly turns into early reading practice — letters become familiar, words connect with sounds, and a love of reading takes root. WHY LUMI?

New stories are added regularly. Learning games: Coloring, puzzles, pattern matching, color sorting, and big-vs-small games. Playful learning throughout the day. A…
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 16 screenshots above are Lumi: Sesli Çocuk Hikayeleri's answers to those questions — they're public, they're real, and they made it through Apple's review.
