I need someone to test 6 language learnings apps & compare them.

I need an individual who is a regular user of mobile language learning apps, preferably for more recreational than professional motivations - such as travel, brain training, skill acquisition, and staying connected with cultural heritage. In this project, he / she will be testing my AI-powered language app alongside multiple other apps and completing a survey in which they will (a) rank the relative importance of different app characteristics to them & (b) grade each app on a 0-5 scale re: how well they satisfy XYZ characteristics.

I'd like for this individual to have used multiple language learning apps and have paid for at least one language app in the past. It would be a plus, but not required, that said individual has some background in software product testing and surveying.
