OtterLearn
Splash into learning! Over 300 games per subject at every grade — math, spelling, reading and science for Pre-K through 6th.
A beautiful learning adventure for iPhone, iPad, and Mac. Every grade level gets its own library of 300+ games in each of four subjects — math, spelling, language arts and science — so a 5th grader never sees toddler games and a preschooler never meets algebra. And every question teaches: the golden "Teach Me" button opens Otter School, where Professor Otter hands over a memory trick or a worked example on different numbers, then asks the child to finish the thinking. No ads, no tracking, no account, and everything a child does stays on the family's own devices.
Mobile
Cosmic Drop
Merge planets. Forge the Sun. A cosmic drop-and-merge puzzle for iPhone and iPad.
Drop adorable planets into a cosmic jar — when two of the same kind touch, they fuse into the next, bigger one. Chain combos, forge the Sun for a supernova victory, and battle through 50 levels across 10 worlds of fire, ice, forest, and storm. One finger. No ads. No account. No internet required. Available now on the App Store.
