ULPT for logging in to my company's time clock thingy?

I have to punch in and out of the company's website for work. This is through Paychex, which is pretty well known. However, one of the horrible c*nts working in HR has set this up so it can't be done on a phone. You have to do this with a desktop or laptop. I've tried with my iphone and ipad, on various browsers, no dice. Short of lugging a laptop around, what can I do here?
