"Challenging settled browsers hegemony"

Reviewed by / Dec 21, 2012

Sleipnir Mobile is a web browser for Android OS with interesting features

[UPDATED]Now you can use each of the web services without having to log in whichever platform you're running it: Windows, Android or iOS. In addition, you can send viewed pages to Evernote, registering to Read Later services, posting simultaneously to Facebook, G+, Twitter, Tumblr... You can also save images to Dropbox and other cloud-storage services.

Sleipnir Mobile is a browser that came to be a real alternative to other settled browser. It's offering some reliable features that really make the difference. First off, it's focused on multi-tasking. For this reason, it allows you to operate multiple pages quickly and easily. How? Thanks to a bottom bar in which you can see thumbnails of open pages. Just tap on the thumbnail to switch from one to another. Likewise, in that bottom bar there's a search button that by default searches on Google.

Gestures is the other great feature of this browser: touch paging lets you switch tabs just by flicking side to side. You can also close tabs "gesturing" a "L", restore currently close tabs with an "U", display search bar with an "S", and many more.

First time you launch Sleipnir it asks you to sync bookmarks. You can do it whenever you want and manage them with default folder or FenrirFS. There's a handy grid homescreen from where you can access all that sites. You can also check out download history.

From settings users can clear cache and history, enable/disable zoom button, scroll grip, enable hold&go, plugins and display modes. We're missing User Agent, bottom bar in horizontal view and other features. However, and above all, what we are missing is more fluency: it doesn't run as smooth as we expected. We encourage its developers, Fenrir Inc., to fix this issue, since it affects directly the usability of the browser.

Besides these catches, it's worth to give a go to it because of gestures, functional tabs and multi-pages view.

    Pro: Can't get more convenient browser for big screens. Excellent offline mode to read later. Touch to go, is more useful than any other features for shopping and surfing. Tabs at fingertips for big screen tabs and phones. No adverts or website thumbnail updating on costly data plans. Suggestions to develop
