Cons

Despite improvements, ChatGPT can still occasionally generate plausible-sounding but factually incorrect information, requiring users to verify critical claims independently.
The free tier imposes usage limits during peak hours, and access to the most advanced models like GPT-4o can be throttled, pushing users toward the paid plan.
Conversation context can degrade in very long threads, sometimes causing the model to forget earlier instructions or details discussed many messages ago.

Lessons can feel repetitive over time, especially at intermediate levels, as the app cycles through similar sentence structures and vocabulary sets.
The free version includes interstitial ads and limited hearts (lives), which can interrupt learning flow and feel frustrating during longer study sessions.
Advanced learners may find the app insufficient for achieving fluency, as it focuses more on vocabulary and basic grammar than complex conversation or cultural nuance.
