Is it necessary to buy a watch, an alarm clock? I now time on the phone, I'm not too punctual

I think the alarm clock can be exempted, but I suggest that you still buy a watch is better, the watch after all, more than the phone to see the time to be convenient, a lift can see, and the phone as well as a relatively large, not very convenient, I see you out of the door do not want to look at the cell phone which is also a reason. And then get up when the alarm clock problem, in fact, many people get up have been accustomed to, not too late, but if you love to sleep will be late, with a cell phone alarm clock can be, you can also choose to cell phone in the softer music alarm, soft wake up certainly better than forced wake up, hehehe

There is also a small tip to sleep, it is recommended that you do not wear a watch, I used to be lazy! I used to be too lazy to take it off, so that's why I bought a watch, although it's a very good one, but it doesn't last long.
