What's New in Number Decomposition

1.3

August 6, 2026

This version fixes issues in the learning system and makes progress more visible. LEARNING SYSTEM • A correct but slow answer used to count as a mistake and reset the task's progress. Now the task simply stays at its current level. • Towards the end, the last two tasks could alternate endlessly without moving on. This is fixed. • Now included: the doubles 2+2, 3+3 and 4+4. Existing progress is preserved. THE DECOMPOSITION IS NOW SHOWN • After a mistake, the quantity visibly splits into its two parts. Children see not only what is correct, but how the number is made up. • Occasionally the decompositions of one number come one after another, making the pattern noticeable. PROGRESS FOR PARENTS AND TEACHERS • Tapping the animal in the settings shows every decomposition with its learning level, so you can see which single task is still shaky. • The tangram animal now gains colour step by step instead of staying grey until a number is fully mastered. • New progress ring for each animal. • A short introduction for parents and teachers on first launch, available again at any time from the settings. EASIER TO READ • Noticeably clearer colours, especially in the pink colour scheme. • The star visibly moves up to the next learning level. • The app now speaks 14 languages. Progress is saved after every answer.
