About

Doomersion (formerly Doomlingo) lets you learn languages by doomsrolling! Watch TikToks in your target language that are exactly matched to your level, and as you scroll, they get a little bit harder. Gen-Z doomscrolls 2.5-3 hours a day, and if we bake immersion into that by only showing them viral videos in another language that are matched to their level, we can make the optimal language learning method addictive for people. Hence the name, doomersion. The app gained ~15k downloads in the first two weeks, and power users spend ~3+ hours daily on the app. Feel free to download and try it yourself!

Basically learn languages by being lazy
