@carlmonkft @Superwall Check out @vahebagdasar’s thread https://t.co/3CQaA89SCO

[Vahe Baghdasaryan @vahebagdasar]

Apple just introduced App Store Review Guideline 2.5.19, and there's already confusion about what it means for apps using remote configuration, paywall or onboarding A/B testing, and more.

[Duncan Crawbuck @dcrawbuck]

@parezem @_DavidSmith @Superwall Yeah that's right, unfortunately it's a limitation with how any third party can measure vs. the data Apple has internally

@JuliK0331 Hey sorry about this, can you open a support ticket here? https://t.co/btEjOaA3uo

Then we can dig into it on our side and figure out what's going on here!

[Duncan Crawbuck @dcrawbuck]

@ereniroh @alannaharv @RevenueCat @Superwall Agree that's a good metric vs. just dollars, I'll get that added to the Superwall dashboard!

Big news: @Superwall acquired Tangent 🤝

4 years ago @vahebagdasar was designing paywalls for a few hundred dollars a pop & posting results to X...

That turned into Tangent:

→ 20+ people
→ 5,000+ experiments
→ 20,000+ paywalls (literally)
→ $50m in added revenue
→ Customers like Cal AI, Eleven Labs & Hallow

Superwall lets you update your paywalls & onboarding in seconds. Tangent knows exactly what to test.

Now we're one company.

We're also finally sharing we raised $7.5M (not recently, we just never really announced it 🙃)

We were profitable before this deal, and we're evem more profitable now. We'll be deploying a ton of capital this year into growth, product & services...

You're going to make a lot more money with us!

Business as usual for all our customers. we will continue to support any customer, regardless of your tech stack. In fact, quite the opposite - now we can work with everyone.

🧵 Superwall had on off-the-record* meeting with someone very high up at Apple yesterday to ask questions about what is and isn't allowed on the App Store. We asked for rules on

→ App2Web
→ Transaction Abandon
→ Free Trial Toggles
→ A/B Testing Paywalls in General

Here's everything we learned...

* Guidelines are intentionally subjective and ultimately up to the reviewer to interpret (more on this in my last post). The only way Apple takes an official stance on a guideline is by updating them.

Some topics may never enter the official guidelines... that doesn't mean they're allowed.

There's a whole layer of internal policy behind the guidelines that isn't written down anywhere and subject to change.

The text you read is just the tip of the iceberg. That's what this thread is about. 👇

Been building this for a while now, finally opening it up.

One UI framework to build and stream native apps for mobile, DOM or Canvas.

Write your UI in Hypen DSL, and your logic in TS, Rust, Kotlin, Go or Swift. Get native UI out on any platform.

Out of the box you get:
- hot reload
- routing
- reactivity
- tailwind support
- responsive breakpoints
- local editor + preview for web, canvas, iOS , Android

Desktop support and WASM stdlib for local apps coming soon.
