These pages load slowly on iOS because it’s currently using a web view inside of the app to load lists and other pages from Skritter. The latest update was a mostly a round of bug fixes and audio corrections that we had collected over the past few months. We’ll be working on a larger update once our site overhaul is finish to try and incorporate some of the larger changes happening on the backend of the Skritter.
It might be a little while before we’re able to implement all of the changes on iOS, but the team is working hard to make that happen as soon as possible.
