20 sound squares turn your ears upside down. Which bird sings? Which composer sounds? Can you put proverbs together and recognize foreign languages? Place your smartphone with the klang² app open in the middle of the table, place a sound square on the reader and listen carefully: Off you go with your acoustic game collection!

The clearest difference is in-app purchases: Logic Cards App at none against klang²'s 10. klang²'s advantage is update cadence (every 2 months vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.
