NeuroNation

[4] The online platform was launched in 2011, and initially served Germany, Austria, and Switzerland.

[5] In 2014, Der Spiegel and XLHealth AG bought a 25% stake in NeuroNation, financing an expansion into English, French, Spanish, Italian, Russian, Japanese, and Portuguese markets.

[8] While the NeuroNation app and similar ones are heavily advertised with claims of improving general cognitive function, there is no evidence to show that NeuroNation or similar programs do so; at most they improve performance in the training tasks given in the program.

[12] In the "Intera-KT" project, NeuroNation collaborated  with the Berlin University Hospital Charité and other partners to digitise paper-based cognitive tests.

[15][16][17] One study by MSH Medical School Hamburg and the University of Würzburg observed that subjects who participated in NeuroNation exercises exhibited improved memory, concentration, and general well-being.
