In your iPhone, open the safari app. On the address bar, enter www.stumbleupon.com/toolbar That’s it. The StumbleUpon toolbar will appear and it immediately stumbles you to one of its pages. To stumble through websites, simply tap on the Stumble button, like how you always did on your computer browser.

Adding to bookmarks

To save the effort of having to retype the URL everytime, you can save the SU toolbar in your bookmark. Everytime when you access the StumbleUpon toolbar, it will start stumbling and append the destination URL to its own, resulting in an URL like https://www.stumbleupon.com/toolbar/#2LpQMi/maketecheasier.com/8-useful-and-interesting-bash-prompts/2009/09/04/topic:Linux%2FUnix. I am sure you won’t want to save this long URL in your bookmark, unless you want to save this particular page for future reference. Here’s how you can change it. On any StumbleUpon page, click the + at the bottom screen to save the current URL to Bookmark. Change the title to StumbleUpon (or any name you like). Note that you won’t be able to change the URL here. Save to Bookmark. Back in the Bookmark screen, tap on the Edit (at the bottom left corner) button. Press the StumbleUpon bookmark entry to go into Edit mode. Change the URL to www.stumbleupon.com/toolbar. Save. That’s it. Everytime you launch this bookmark, it will start stumbling. Personally, I found that using StumbleUpon on my iPhone drained my battery much faster than normal browsing. I am not sure if it is only me, or this is a SU issue. If you have such issues too, feel free to voice it out in the comments.
