Meet Appin: Your Guide to PWA and Home Screen Tips

Hi, I’m Appin.
I wander around OJapp Tips, helping explain PWAs, home screens, and the sometimes strange behavior of Web apps.
Whenever something starts to feel a little too technical, I might pop up with something like:
“Wait, what does that mean?”
or
“This is the important part!”
You’ll see me here and there throughout the articles.
So, who is Appin?
Appin is a character born from OJapp’s home screen icon.
My job is to make things OJapp has actually tested—PWAs, home screen behavior, Web apps, and all the little browser quirks—easier to understand.
I especially like home screens.
Where you’ll usually find me
- OJapp Tips articles
- PWA guides and explanations
- Anything about the home screen
- Places where you might wonder, “Why does it work like that?”
- Results from OJapp’s experiments
If you spot me, just think, “Oh, there he is again.”

You’ll be seeing me in plenty of places around OJapp Tips from now on.
