Unlike other Linuxcompatibility layermobile apps, UserLAnd does not require a root account.[2][3][4][5][6][7][8][9][10] UserLAnd's ability to function without root directories, also known as "rooting," avoids "bricking" or the non-functionality of the mobile device while the Linux program is in use, which in addition to making the mobile device non-functional may void the device's warranty.[4] Furthermore, the requirement of programs other than UserLAnd to "root" your mobile device has proven a formidable challenge for inexperienced Linux users.[6] A prior application, GNURoot Debian, attempted to similarly run Linux programs on mobile devices, but it has ceased to be maintained and, therefore, is no longer operational.[6]
UserLAnd allows those with a mobile device to run Linux programs, many of which aren't available as mobile apps.[2][3][4][5][6][7][8][9][10] Even for those Linux applications, e.g. Firefox, which have mobile versions available, people often find that their user experience with these mobile versions pales in comparison with their desktop.[11] UserLAnd allows its users to recreate that desktop experience on their mobile device.
To use UserLAnd, one must first download – typically from F-Droid or the Google Play Store – the application and then install it.[4][5][6][11] Once installed, a user selects an app to open.[4][5][6][11] When a program is selected, the user is prompted to enter login information and select a connection type.[4][5][6][11] Following this, the user gains access to their selected program.[4][5][6][11]
A review on Slant.co listed UserLAnd's "Pro's": support for VNC X sessions, no "rooting" required, easy setup, and that it's free and open-source; and "Con's": its lack of support for Lollipop and the difficulty of use for non-technical users.[14] On the contrary, OS Journal found that the lack of a need to "root" your mobile device made using UserLAnd considerably easier than Linux compatibility layer applications, a position shared with SlashGear's review of UserLAnd.[6][8] OS Journal went on to state that with UserLAnd one could do "almost anything" and "you’re (only) limited by your insanity" with respect to what you can do with the application.[6]Linux Journal stated that "UserLAnd offers a quick and easy way to run an entire Linux distribution, or even just a Linux application or game, from your pocket."[3] SlashGear stated that UserLAnd is "absolutely super simple to use and requires little to no technical knowledge to get off the ground running."[8]
