Ratings and reviews

Almost good. It shows an error when attempting to upload a picture then the chat is corrupted: Error: Field 'id' is required for type with serial name 'dev.chungjungsoo.gptmobile.data.network.OpenAIFileResponse', but it was missing at path: $

I had trouble with the API keys and couldn't move any further but the idea and concept is great for those who use Chat GPT and Gemini. I did notice that 2 services out of 4 were subscription only which was a bit of a bummer, unless you have a sub for it. Make the API stuff automatic or much easier and I can see a lot of people using your app. Nice work!

This is absolutely my favorite AI chat app. It is simple and has exactly the features I need and nothing more, no useless fluff. The only downside - it hasn't been updated in a while, so it doesn't allow you to add newer models. I hope the author picks it up
