My ChatGPT Android App working Via API (Available on PlayStore)

I made android app of ChatGPT that working throught openAI Api. My aim is to bring chatGPT in every pocket with almost zero struggle. The big question is why i made this app when anyone can use ChatGPT directly?
Well we know ChatGPT is trending nowadays due to high demand most of the time we face the following issues

  1. Capacity Full
  2. Sometimes asking to login again
  3. Most of the time it shows some red error and asks to complete captcha
    But my app uses api so it doesn’t have such issues (I know sometimes Api is also down but most of the time it works fine). I need your reviews friends.
    Here is My app link:
