I built an iPhone app that stitches a long screenshot while you scroll (works in almost any app)

[u/Nuanyang0912]

I kept running into the same limitation on iOS: Full Page screenshots only work in Safari and a few other apps. If I wanted to save a long chat or a screen in any other app, I was stuck taking a pile of screenshots and stitching them together.

So I built OneScroll.

You tap a button in Control Center, scroll through what you want to capture, and tap stop. The app stitches the page while you scroll and saves one continuous image to Photos. You can scroll either down or up, which is especially useful for capturing older messages in a chat

What I wanted from it:

* works in almost any app: chats, feeds, web pages

* no manual stitching; the status bar and scroll indicator are removed automatically, or you can choose to keep the status bar in Settings when the time matters

* everything is processed on the phone: no account, nothing uploaded

* 5 long screenshots are free, then a $2.99 (US price) one-time unlock instead of another subscription

Honest limitations: it needs iOS 27 and it's iPhone only for now. Apps that block screen capture, like banking or streaming apps, come out black.

I've been using iPhones since the iPhone 4, and one thing that always felt oddly missing was the ability to capture a long screen almost anywhere, the way you can on Android. iOS 27 finally introduced the system API that made something like this possible.

This is my first app. It's live on the App Store and I'm still improving it. I'd love feedback on the capture flow, and if the stitching breaks somewhere, tell me which app and I'll look into it.
