Cal AI got removed from the App Store today. The Cal AI, the one with 15M+ downloads, $2M in store revenue last month, acquired by MyFitnessPal. Gone. Two days ago, a tweet went viral exposing their paywall setup: Stripe payment sheets appearing natively inside the app, instead of opening in the default browser. This violated the ToS and probably is the reason for the removal, the timing matches. This is just a reminder that if you are building app funnels, where you are processing payments, check before any updates, because Apple's review policies do not play around. With web2, you have a lot more control, but with web3, you have a lot more of the payment flow that is untouched. If today's news scares you, you should check your paywall link, check your account and expect to be removed until you launch a fix.
