Suggestions for the Best Apps (Free/Paid) or courses to Become Fluent in English

I am looking for some app suggestions which improves my English speaking skills and also expand my vocabulary.

I am good at reading, writing and grammar but struggle speaking to someone fluently.

I am looking for app which helps me practice speaking and corrects me , give me tasks to improve myself speaking or improve my vocabulary.

Preferably, apps that have AI or tutor-based interactions (AI preferred)

I’m open to both free and paid options and willing to subscribe if the app is worth it.

Please suggest me apps that would be really helpful
