What Is This App?
It’s a React Native app built with Expo (SDK 54), running on the Hermes JavaScript engine. The backend is WordPress with a custom REST API. The app was built by an entity called “forty-five-press” according to the Expo config.


I can’t say anything about the content of this blog. It was horribly laggy to scroll on mobile device. And by horribly laggy, I mean like aunt’s 1986 vacation slide show on a projector while having dry cookies and tasteless off brand earl grey.
I’m sorry if it sounds rude but I had to bring this on out in the open. What even runs under the hood on that blog…
I had no issues, and I am on a cheap boomer phone that installs games without permission every so often.
It’s a bit funny that it’s completely at odds with how they describe their goals (emphasis mine):
I didn’t have any problem on my Android phone
It wasn’t horribly laggy on my Pixel but it definitely was less performant than a page like this should be.
Holy shit, i thought i was gonna have a seizure first time i scrolled
Even if the effect didn’t lag, there’s almost no added benefit to it. The title is cut off, and the description is even worse.
If the author wanted to, they could have done something like this with no scripts, minimum effort, and probably zero lag.
(If OP’s website chugged for you, I’m curious whether this demo is seamlessly smooth. It is for me.)
Strangely enough, for me both blog post an demo didn’t lag, but the transparent sticky title did look bad
Smooth as cub’s fur.
Like its locked to 10fps
Worked fine for me, but I block ads and trackers on my home network so that probably helped.
runs perfectly fine on my laptop with firefox
Yea for me too, it appears to be something we the title header following your scroll. It’s super smooth just until it tries to pin it to the top.
Reader mode works until I realised that they did explain the pictures, so just referenced text I didn’t see.
Not a performance problem.My guess is, they (poorly) emulate native scrolling via JSon mobile. Probably for some progress feature or something.JS disabled, scrolling works. Though it was only slightly laggy for me.
Unfortunately all of the code blocks are loaded after-the-fact with JS for some asinine reason (highlighting I’d understand… but why the actual text?), so disabling JS also disables all the code snippets on the page.
That’s why dynamic loading sucks.
Definitely a performance problem, no HW acceleration on PC produces the same insanely stuttery scroll.
