Ratings and Reviews
Great app, plenty of useful info, easy to use.
Handig en duidelijk
Een Periodiek systeem op zak, geeft beknopte informatie over elk element, wie het ontdekt heeft, de basisgegevens zoals kookpunt etc. Leuk om een keer paar keer door te bladeren en handig voor mij op school tijdens de natuur- en scheikundeles/huiswerk.
Voor al de informatie geen wifi nodig, alles staat op je iPod zelf!
En uiteraard alles in 't engels..niet in 't duits zoals de plaatjes suggereren.
Eenvoudig het beste periodiek systeem wat er is. De filter-opties zijn bruut, de hoeveelheid data enorm en de presentatie fantastisch! Hulde!
