I use my Samsung Note 3 and my Surface RT to access Lansweeper using the Chrome mobile browser all the time. If your Wifi allows you to access the corporate network, you can either use the DNS name or the IP address (depending on Wifi restrictions) in the following format: http://servername:portnumber or http://ipaddress:portnumber.
When it prompts for credentials, just enter in your username and password in the following format: username only (no DOMAIN\username or username@domain.com) and then your domain password. This will sign you into the Lansweeper portal.
You cannot do a lot of items on the mobile device, but at least you can look up items or even look up reports and rescan assets. A lot of the custom actions will not work since you have to modify the browser settings and I have not taken the time to get that far into it since I usually always have my laptop close by.
