> And who has his laptop with him when lying in bed and checking the wake up time.

Me! ^

I'm a poor college student with a dumb phone and a single room. My laptop sits on my desk, which is in the same room as my bed. Unless your mobile version works on an 07 Motorola Razr, and doesn't require a data plan, I can't use it. I assume this is not the case, so if you want to cater to my demographic, please make sure the site is usable through a normal browser without a touchscreen.

Note that my demographic isn't likely to drop a lot of money on an app that does this, but I'm not sure it's worth much at all.

^ OK, so I actually use a normal alarm clock and I get up and go to bed at the same time every day (calculated with this in mind).
