Egy új típusú iskolai atlasz alkalmazása. Sok mindent nem a nyomtatott változatban találsz meg, hanem digitális formában 3D-s ábrázolásként, kiterjesztett valóságként vagy interaktív alkalmazásként segít téged a tanulásban. Az új technológia számtalan érdekes és új tapasztalatot tartogat a mindennapi tanuláshoz. A mobilapplikációknak köszönhetően kevesebb papírt használunk fel, ezzel kímélve környezetünket, az atlasz lapjai pedig nem avulnak el, hiszen a kiegészítő tartalmak rendszeresen megújulnak majd.
