Marvin Velasco, a former daily user of Duolingo, became disillusioned after a year due to repetitive lessons and a lack of new content, leading him to uninstall the app despite a streak of over 500 days. Upon returning to refresh his German skills for a trip to Europe, he found the app cluttered with ads and unrelated features, which detracted from the language learning experience. The introduction of a new energy system limited his lesson completion and emphasized subscription tiers over genuine learning. After a trial of Duolingo Super, which he found gamified the experience, Velasco switched to Gemini, appreciating its user-friendly interface and personalized study plans. He tailored his learning with Gemini to focus on conversational German without the stress of losing streaks. Despite its flaws, he kept Duolingo for its structured modules, using both apps to create a balanced approach to language learning. He improved his experience with Duolingo by using it on a web browser to eliminate ads and disabling competitive features.
