Honest answer: it is a commercial app with a 14 day free trial and the login is tied to that. No deeper technical reason. I understand that this is annoying when you just want to try it. I will think about a local-only mode… Thanks for the question.
Appreciate the directness, but pro-tip from an ex-mobile dev; you'll convert way better with IAP subscriptions rather than your own account system
In the README it says
> Do I need an account to try it? Not for the core breathing biofeedback; that works without creating one. Some surrounding features in the app use an account; the part this repo is about does not.
I downloaded the app based on this, but you can’t use it at all without creating an account. Please review your AI’s output.
