## What is iDocSet?

iDocSet is a tool for reading offline docsets. 

With iDocSet, you can leave your Mac alone, reading your favorite docsets on mobile devices (iPhone or iPad) anywhere, anytime.

Main features:

* Support browsing Apple Developer Documentation of Xcode 12 or later.

* Support browsing more docsets.

iDocSet has a built-in download source and supports more than 50 docsets, such as HTML, CSS, jQuery, C++, Go, Rust, ... 

After the user adds a docset, it is automatically downloaded and installed, and the auxiliary tool iDocSetHelper is no longer needed.

### 2/5 — Don't bother

*2016-12-15*

This app is too buggy to use.

**Developer response:** Sorry for any inconveniences. Please use iDocSetHelper to upload your docsets from mac.

### 5/5 — The best docset viewer on the App Store

*2014-11-08, version 4.1*

It works perfectly, and unlike similar apps, it is updated frequently, and it is compatible with iOS 8 and OS X 10.10 docsets. The idocsethelper app makes uploading the various docsets very simple. All in all, it's excellent.

### 1/5 — import broke

*2014-09-24, version 3.3*

only works with builtin docset which is for idocset making the program worthless. i cannot get it to recognize any other docset i have tried.

### 5/5 — Imported all docs from Dash

*2014-08-12*

I managed to transfer all my docsets that I had on Dash to this, with the exception of the man pages.

### 4/5 — Good, but...

*2014-05-11*

Could be so much better. As it stands it is better than DocSetViewer,as it can import from your OSX machine the Dash docsets, which for me is significant - I can now have ready offline a wide variety of disparate sdk apis.
But - the browser panel needs to be maximisable - might sound picky, but you try reading some of these pages in a panel not much more than half the width of the ipad screen. Should be easy to make happen - lots of other apps do this. Come one dev - then I can give the app the deserved 5 stars!

Oh - and make the left hand panel handle longer text items better - at the moment they get truncated/not displayed, beyond a certain number of chars.

### 5/5 — nice app. does what it says.

*2014-01-01*

maybe options like changing font size and uploading files via usb rather than wifi would make it better.

### 1/5 — Worse

*2013-07-25, version 1.1*

Won't find a docset uploaded with iTunes sharing. Useless.
Update: after following annoying instructions to use docsetutil it found the xar but now crashes when browsing to the docset in the app. Useless.
