Your phone is generally not seen as a stress-reducing factor. Soon your phone may be able to measure how stressed you are. But the real relaxation, you will have to do that yourself.
Procedure
An app is currently being tested that can measure how stressed you are. What do you need? The app, a special comic and some spit. Spit on the strip and the app will show you how much stress you have.
Cortisol The app measures how much cortisol you have in your body. Normally, your cortisol level is highest in the morning and decreases as the day progresses. When stressed, an extra 'shot' of cortisol is released and that is exactly what the app measures.
Gauge
Although the app will show you if you are stressed, you will still have to deal with your stress yourself for the time being, because relaxation therapy is not yet included in the app. The app is expected to be released in 2015.
