Not working

Does not work on iOS 9.

Nice but need improvement

The display on my iphone 8 is not pleasant, on my mini2, everything else is good but the figures of PDUs are in a mass. Without being able to show an RFC in a well aligned format, it is not a finished product. I hope the developer can add options like display in html format or something else, so we can read an RFC like reading with a text editor on a desktop PC.

Now I set it to courier and font size 14, the display is aligned on iPad mini2, suggest to set courier as the default font.

Great basic RFC search and reader

Very fast RFC title search with clear bright red successor RFC listed in search results. Screaming fast RFC viewing. 4 stars because I'd add the following feature: Enable filter flag to exclude obsoleted RFC OR filter to show latest RFC in chain (my favorite of the two possible options.
