I'd like to know what precise version of Mobile Safari the iPad I'm using has. Is there any way to find out (preferably from the device itself)? There doesn't seem to be any menu in Safari Mobile, and thus none to choose "About" from. If you go to Settings | Safari, you see various useful things, but no "About" or "Version" or similar, which surprised me.

+1 good question. Apparently Safari does not support any of the about: pages en.wikipedia.org/wiki/About_URI_scheme –  Thilo Nov 10 '11 at 4:53
@Thilo: But we should be kicking ourselves; it does, of course, support the javascript: pseudo-protocol. See Ross's answer. Doh!! –  T.J. Crowder Feb 26 '14 at 15:47

You can get the userAgent string without visiting an external website, by typing the following in the Safari address bar (where you would normally type a URL):


You must type it exactly as it appears here, matching case and punctuation.

An alert popup will appear with the full useragent string, which contains the version number of Safari and iOS.

What. Was. I. Thinking? Of course, the javascript: pseudo-protocol and navigator.userAgent. –  T.J. Crowder Feb 26 '14 at 15:46

The only way I've found Ross's way is much better, but another way to do this is to use an external website (there are plenty to choose from, just search on "what's my browser"), which will report my user-agent string back to me.

So for instance, these sites will report back to me that my user-agent string is:

Mozilla/5.0 (iPad; U; CPU OS 4_3_5 like Mac OS X; en-gb) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8L1 Safari/6533.18.5

...from which I can tell that I'm using Mobile Safari 5.0.2.

For example: show-ip.net/browserinfo –  Gerry Nov 9 '11 at 16:41
I didn't even realize you were answering your own question, but to confirm: yes that would be the only way. You could condense a list of iOS versions and installed Mobile Safari and use that for reference, if no one else has done it already... –  Gerry Nov 9 '11 at 16:45
@T.J.Crowder, you should probably accept your own answer - it's the best way of doing what you asked. –  JW8 Nov 9 '11 at 23:39

Handy alternative if you want to copy paste this info / you're already there: plug your iPad into your mac (assuming platform!) and in OSX Safari, remote debug the device, and copy the User Agent from the Resource Panel under Request Headers.

Enable remote debugging:

  • In OSX Safari’s Preferences pane under Advanced, check the Show Develop menu in the menu bar checkbox.
  • On iDevice: Settings > Safari > Advanced

None of the javascript answers worked for me. I found an easier way! This link: www.whatismybrowser.com. Type it in the address bar and it will tell what the browser is, what your operating system is; And! If your browser is up to date! No mucking around! All the best.

"None of the javascript answers worked for me" Huh? javascript:alert(navigator.userAgent) definitely works. –  T.J. Crowder yesterday

You can visit http://spiderip.com to check the user agent and version of safari

Could you explain why this works, not just a link. Just goiving a link makes me think of viruses and trojans etc. –  Mark May 9 '13 at 12:17
This works because on every request the browser send this information to the webserver. But usually you just do not see this and this webpage just "reflects" the information passed via the request. –  user72693 Mar 11 '14 at 9:50
