Cal AI has been removed from the App Store

This kid is living the dream

@MyFitnessPal just lost +$100M in 45 days (?) assuming they paid a 4X multiple for @calai_app, and that @Apple is banning the app forever, @MyFitnessPal just did one of the worst investments in the mobile space history kudos to the Cal AI team for the great exit. maybe one of the best exits in human history


didn’t think Cal AI would get taken off appstore cause of this tweet

payment sheets have been ripping lately ARPU with stripe is much higher cause of less fees + higher friction cancellation if ur building an app look into using this only select clients of superwall have access

Claude now requires government ID verification (via Persona) before subscription. ChatGPT doesn't. Gemini doesn't. Anthropic just handed their competitors a gift.

This is obviously a paid promo for Superwall. Disappointing. Other notes: 1. App Store rules require opening an external browser to complete checkout. This UI is completely fake or gets you banned. 2. 90% of txns for trials will be through $0 balance prepaid cards and fail.
