Today is my last day at @CitizenApp where I joined 4.5 years ago as PM #1 . I helped get our revenue off the ground and was promoted to lead the Product and Design team. I learned a lot of lessons the hard way, so it felt like a good time to share my guiding principles. A 🧵 1/7

@zackkanter Long term retention on IAP (Apple’s sub service) is much worse than on Stripe. Best in class 12mo on Stripe sub is 60%-80%. On IAP, best in class 12mo closer to 30%-50%.

@zackkanter Apple bundles all subs into one area and if a consumer goes to cancel one often “power cancel” all. To juice services revenue, I expect Apple will move subscription management into individual app settings with affordances to pause, cross sell, etc.

This is really strong writing. An underrated method of evaluating TAM is the refresh rate for a given market. e.g. Apps that target high schoolers get a steady refresh every year, the housing market seems big but can freeze up as interest rates rise.
