SINGAPORE (Reuters) - Each morning before work at a Singapore construction site, Gunasekar Udayakumar, 41, gets his vital signs checked, without going to a clinic, or even seeing a nurse.

All he needs is his smartphone, which in just 45 seconds can tell him his heart rate, oxygen levels and even his stress levels.
