The data stored on the polybox servers are stored on the central storage facilities of the ETH Zurich. Using the service polybox avoids the usage of external (uncontrollable) storage. Sync Clients are provided for an efficient and easy use of the service polybox for all common operating systems (mobile as well as desktop). All ETH members have access to the polybox service. On the first login on «polybox.ethz.ch» with the ETH account, an account with 50 GB of storage is created automatically.

Die App "3D-Chemie" wurde in Zusammenarbeit zwischen dem ICBT und dem IAS (www.zhaw.ch/lsfm) entwickelt und durch Förderungsgelder für E-Learning durch die ZHAW finanziert. Durch die App soll das dreidimensionale Vorstellungsvermögen der Studierenden für molekulare Strukturen geschult und gefördert werden, da die dreidimensionale Struktur molekularer Verbindungen häufig das Verhalten bzw. die Funktion erklärt oder bestimmt. Die Studierenden sollen zudem in die Lage versetzt werden, chemische und biologische Strukturen unabhängig von spezifischer (und teurer) Software visualisieren zu können. Zudem sind neue Strukturen durch Dozierende einfach erfass- und vermittelbar. Weitere Informationen unter www.zhaw.ch/3dchemie

The clearest difference is update cadence: 3D at every 9 days against ETH polybox's every 6 months. 3D also leads on iOS requirement (9.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
