What are some potential reasons for Duolingo's impressive 64% installation rate compared to Rosetta Stone's 2%?

Rosetta Stone could implement several strategies to regain its market share in the language-learning app industry. First, it could focus on improving its user experience to make it more engaging and interactive, similar to Duolingo. Second, it could introduce a freemium model, offering basic lessons for free and charging for advanced features. This could attract new users who are hesitant to pay upfront. Third, it could invest in marketing and partnerships to increase its visibility and reach. Lastly, it could continuously update its content and incorporate new languages and cultures to keep users interested.

Duolingo managed to surpass Rosetta Stone as the most installed language-learning app through a combination of factors. Firstly, Duolingo's freemium model made it more accessible to a wider audience. Secondly, Duolingo's gamified approach to language learning made it more engaging and fun for users. Lastly, Duolingo's mobile-first strategy allowed it to capitalize on the growing trend of mobile learning.
