An iOS tweak that unlocks Goodnotes Pro
Goodnotes uses RevenueCat to manage subscriptions. Every time the app starts, it sends a request to a GoodNotes proxied RevenueCat's API (/v1/subscribers/<user_id>) to check your subscription status
BadNotes hooks NSURLSession's dataTaskWithRequest:completionHandler: at runtime ; and when the app makes a request to that endpoint, the tweak intercepts the response and replaces the JSON body with a crafted payload that tells the app u are Pro
That's basically it !
Some features are server-side and won't work (AI features, collaboration, etc...)
