This is like no alphabet song your child will ever hear because this is a song they will create themselves! By putting letters in the tray your child experiences tactile reinforcement as they decide on letters, queue them up, and take control of their song. This is where a multi-sensory, transmedia juke-box meets a lullaby music video! Take a journey through Square Panda's imagination where any alphabet song creation is possible! Your child engages with two different modes, one to create the song and one to review the new words learned. Watch in delight as your child's lullaby comes to life! Perfect for children learning: the Alphabet, letters, letter sounds, concepts about print, word families, word endings, and vocabulary Features: 26 letters songs in hundreds of combinations for a unique alphabet song experience every time! Contextual reinforcement of words with pictures supports comprehension and vocabulary acquisition Review mode allows for children to interact with key words that appear in the song lyrics Phonics Benefits: Children learn that symbols correspond with specific phonemic sounds and when placed individually or together create brand new sounds. These sounds tied together have meaning and this meaning is the construct for the entire English language. For ages 2-3. Square Panda Playset required to play.

Both are free to download. Osmo Math Buzz sells 2 one-off in-app purchases. Square Panda Letter Lullaby asks for nothing beyond the download.
Square Panda Letter Lullaby holds the better App Store score, 3.2 against 3.0. That said, the two scores are not equally well evidenced: Osmo Math Buzz has 143 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 0% of Square Panda Letter Lullaby's written reviews are positive against 13% of Osmo Math Buzz's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 2, 2026 and October 21, 2026 respectively.
