how to price app subscription services?
Hello, I have a service and there are a lot of people I asked to test the app, and they said they like it and are ready to buy. Some said it will help and they will pay 20, some said they will pay 40, but the usage is different.
The problem is that in my app I use Gemini and OpenAI models, so there is a cost for each reaquest.
From what I searched, I found that the best thing is to use a credit system and link each one with a specific API key, so if someone buys, they get $20 credit in OpenAI or Gemini, and if they need more they can buy it.
I think this idea is good, and I see a lot of apps use this. But my question is how to calculate it exactly, because I have some other services that don’t need AI and they use it also.
If I use only AI, how much profit margin should I get? $5 from $20 or what?
I need your experience and suggestion.
