SCP Wiki in BPT? I fuck with that.
There's a halfway decent offline version of the SCP Wiki for Android here if you care about that for some reason.
I was using this for Android. It has offline, which is awesome for those of us who want to read SCP on commutes that don't have consistent signal.
But the developer hasn't updated it since April ~~2005~~ 2015 and the pictures don't load anymore. There are other apps, but this one was arguably the best. Now that it has janked, I'm going to be installing them all to see what's the best of the rest.
Edit: That... was a weird mental typo to make.
Not exactly what you're asking for but when I don't have an internet connection I use this app to browse the SCP database. It's bloody huge (1.7 GB) but it has every SCP up to series 3 and a lot of stuff from the SCP wiki. There is also a light version, which is smaller in size but without any pictures.
There is a paid version without ads, but there is no need for it, as you can just disable your WiFi/data and ads will stop loading (that applies to all apps btw)
I use this app for offline reference while in the field.
Cool! Found it for android- https://play.google.com/store/apps/details?id=com.nn5n.scp.foundation.db
