Familiar with that dreaded language learning phase of having to sound like a 3-year-old long enough to make actual progress? TVÍK is here to make sure you do not have to do that in front of real, scary people. TVÍK is built by humans who went through the dreaded process of learning Icelandic by themselves and know exactly what's missing. TVÍK takes you through 84 realistic simulations. You'll get to go on adventures, meet TVÍK's friends, there will be drama, and there will be Gunnar. You'll learn the Icelandic of the streets, not the Icelandic taught in books. There is a soundtrack. Almost everything is a button, too! Aside from simulations, TVÍK comes with a full language learning gym to make sure you flex your brain muscles and transfer new knowledge into long-term memory, and a Toolbox to make sure you've got easy access to all of your Icelandic resources.
