### 5/5 — Update Awesomeness

*2021-09-12*

Thanks Fei, this update has fixed my rendering problem and now with the options for text, PDF and HTML it has made my happiness today! Thank you so much! App highly recommended to others, especially those that like to access and read RFC quickly!

**Developer response:** Thank you very much for your comments

### 4/5 — Beginnings of a great app

*2020-05-31*

Searchable. Very fast. Great viewing experience. Highlights and markings.

Three additional features I'd love to see:
1- filter obsolete RFCs
2- ability to write notes that attach to highlights in the RFC
3- sync settings, favorites, highlights, and notes across multiple devices
4- support for dark mode

**Developer response:** thanks for the comments, will take into consideration in next update

### 3/5 — Nice but need improvement

*2018-02-03*

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.

### 5/5 — Only one on IOS

*2017-12-09*

Please keep it going. Nice start

### 3/5 — A little bit behind

*2016-09-22*

One rfc I read am currently reading is 7938 no it is missing from the app. Looked through the list and the rfc's stop at 7899.

### 4/5 — Great basic RFC search and reader

*2016-03-14*

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.

### 4/5 — Nice and Simple

*2016-01-28*

This is a a very nice and simple RFC viewer and downloader.

### 1/5 — Not working

*2015-09-20*

Does not work on iOS 9.
