Yes, all questions within the app are free to use. The developer offers a paid 'Serious Study Plan' for users who prefer an ad-free experience. ### How does 英検®英単語 compare to generic language apps like Duolingo? 英検®英単語 is specifically curated for Eiken certification requirements, whereas generic apps offer broader, less targeted vocabulary. It is better suited for students specifically preparing for Eiken Grade 3 through Grade 2. ### Does the app work offline? The app requires an internet connection to display advertisements. Users concerned about data usage or connectivity may prefer the ad-free paid plan, though some features may still require a connection for data syncing. ### What is a good alternative for Eiken preparation?
