Fluency in English means you can express your ideas without long pauses or getting stuck. It is not the same as speaking fast or using difficult words. Fluent speakers can keep a conversation going, use common phrases without thinking too much, and recover from small mistakes. Fluency grows with regular speaking practice, not only with reading or grammar exercises.
Fluency comes from using the language often. When you speak repeatedly, your brain starts to recall words and patterns faster. You need both input (listening, reading) and output (speaking). Apps like Rozy focus on output: real conversations where you produce sentences and get instant feedback. Doing a little every day is more effective than rare long sessions.
Accuracy is using correct grammar and pronunciation. Fluency is speaking without too many pauses. Both matter. At first, many learners prioritise accuracy and speak slowly. As you practise more, you can work on keeping the flow going while still fixing important mistakes. Rozy helps you balance both by correcting you in real time without stopping the conversation.
