Stress is the root cause of many illnesses. Measure your stress to manage it!

- What is the principle behind StressScan? −
Many of the functions essential to maintaining human health are controlled by the autonomic nervous system. It is medically recognized that the balance of the autonomic nervous system can become disordered through fatigue and other stress, stemming from causes such as work and human relationships. By analyzing the waveform of your heartbeat as measured at the fingertip, StressScan can analyze the balance of your autonomic nervous system and measure your stress level on a stress index of 1 to 100.

- You can trust StressScan! -
The technology used by StressScan is based on heart rate variability analysis, which is widely recognized in the field of heart rate analysis and autonomic nervous system research.
Although heart rate variability analysis technology is not yet generally well known, many medical institutions and companies have taken an interest and are beginning to put it to use. The technology is seeing use even at the cutting edge of stress care, including adoption by the US military to treat post-traumatic stress disorder (PTSD) in soldiers returning from the battlefield, and by NASA for astronaut training and health management.

- Usable in a range of scenarios! -
· Periodic checking of daily stress level
· Checking the effects of favorite meals and drinks on stress
· Checking relaxation while traveling or at a favorite spot

- Device compatibility -
The app is intended for use with a camera- and flash-equipped smartphone. It is not usable with devices that do not have a camera and flash.

- Usage environment -

Nice app


Use it everyday! And it easy and fast, the ads aren’t good bad but it would be nice to have a Ad Free one I be willing to pay a little for that. also should come up with an Apple Watch app so it can use the Apple Watch Heart Rate measurements as well

Very good


I've used other free stress check apps this is my favorite so far. It's accurate easy and ads aren't too intrusive. It also checks my heart beat accurately so I don't have to use another app for that. Ricommend.

Great app
