Got an android tablet and checked out the app and because it the full web page I dont seem to be able to checkin as the buttons are not there like i see on my android phone. I might be being blind.
Probably another browser compatibilty hack that needs to be catered for. :D
Dont exactly need it but just thought you should know.
Actually getting to grips with the browser now, I can set it up to appear as a tablet, desktop or mobile. If i choose mobile then I am able to checkin, desktop and tablet don't allow. False alarm.
